[@Nomaran]

Yay! Linux content! Love proxmox

[@vonkruel]

I've recently spent some time playing with Proxmox in a VM, and I'm impressed. I think this is what I'll install on my next server. When you install Proxmox (with no subscription), after you fix the APT repository and pull in updates, run this: sed -i.backup "s/data.status !== 'Active'/false/g" /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js && systemctl restart pveproxy.service Ta-da, no more subscription nag when you log in to the web UI (might have to clear browser cache). Put that in a shell script so you can run it each time you pull updates.

[@MakersEase]

I just started looking at proxmox for a small company... We have it installed on a couple R720's to play with. When we finally got to the point were we pulled the network cable on the main machine running the windows vm's and they magically appeared running on the 2nd node (setting up replication and HA).... Awesome! We certainly have a bit to learn but love these videos! (mainly to know what we are doing wrong) ;)

[@TheRebel2014]

Thanks for this! I don't have an EPYC quite yet, but more Proxmox content is really nice to have. It's something I use enough that I love having videos explore what is possible with it and how to use it.

[@origamihawk]

This will be very useful for the epyc server I can totally afford

[@gearspider]

I would love a Wendell comparison of these major virtualization implementations; Proxmox, Unraid, FreeNAS, XCP-NG, Xen (standalone).. I am planning a home server to do various things and my buddy in the hosting industry suggests Xen (standalone) to me, but whenever I research it online, everything is about XenServer or XCP-NG.. A detailed explanation of these different products would be amazing!

[@3nertia]

[@PlanetFrosty]

Very interesting and you’ve got my interest in Proxmox. Excellent work.

[@180doman]

Oh and Yes! I would love to see setting up proxmox cluster. Especially because AFAIK there is no easy way of doing host backups on single node setup (only vms and cts backups).

[@vonkruel]

I'm new to Proxmox and I'm interested in the best way to do host backups too. There may not be a lot of files added/changed on the host compared to a fresh install, but it would still be nice to avoid identifying all the files that need backing up & just make a full backup. This could be a reason to choose ZFS when installing Proxmox, since you could then snapshot the host & back that up.

[@kavehminooie3331]

it would have been great if you could do a comparison with xcp-ng , or in terms of performance, with a container only solution like coreos. thanks for the video

[@mikel8190]

I would love to see you make more proxmox content. Really good information in this video

[@KIWIDOGGIE]

[@JoaoSilva-gs5jb]

Wendel! You're just amazing ! Compare proxmox with xcp-ng, planning on a homelab server to run bitwarden, plex, nextcloud, 2 VMs for gaming and some other VMs to test windows and linux distros for work!

[@Kamel419]

just so you know, i've been using linode for at least 5 years, which was based on a comment you made about using them (not even a sponsor at the time).

[@andljoy]

What are the pros and cons of Proxmox over XCP-NG . Most importantly , will it let me import a 48 disk freenas pool ?

[@bobsyouraunty]

I tried importing from freenas to proxmox without luck. Different feature set, so it was listed as incompatible. Could've changed now though, this was a year ago.

[@kodeypatterson8973]

Proxmox is finicky with hard drives. If there is ANY partition data left on the hard drive, Proxmox will not display it in the gui at all. You’ll have to then use the command line to format it completely before Proxmox will recognize it. There’s no place in the gui to format drives that have partition data so it can be confusing when you have so many drives and none show up because they have a single photo on it. I know because I migrated from freenas also

[@Teknickel_ftw]

You could run freenas in a vm and pass though all the drives. Craft Computing did a video on it.

[@ajshell2]

I've moved from FreeNAS to Proxmox without issues. But I was rather conservative in choosing flags for my FreeNAS pool and I've never run "zpool upgrade". Fortunately, the lastest Proxmox update added ZFS on Linux 0.8.3 support, so it probably supports more features now.

[@nos676]

great video's wendell! please make a vid for HA, Ceph, and perhaps compare Proxmox, XCP-NG, & Xen. I'm setting up some new hardware in my homelab for virtualisation, and it would be greatly appreciated.

[@theNISK]

amazing content, more of this!

[@redneckrestoration9385]

More Linux please :)

[@b2bb]

Linode comin in clutch

[@csstack]

For the determinism slider, if you want the highest performance possible you will want to choose Power, not Performance. I know it sounds counterintuitive, but check out AMD's Power Performance Determinism whitepaper, or some of their tuning guides which provide a better understanding of how Power Deterministic allows you to extract the maximum performance from your processor.

[@johnbuscher]

This is fairly interesting. My limited understanding thought unRAID might be a better solution, but after looking a little more at it, only if storage configurability is a higher priority while the VM features were added later. So proxmox would be great for the host, it looks like, if I build a homelab.

[@tomyy666]

[@BulllRush]

HA on ProxMox is very appealing to me, especially considering some of the features that ProxMox enables without really expensive licensing

[@0ctatr0n]

Hey Wendell, could you do a video on using docker-compose with Cockpit or portainer, Then setup a couple of services like a web server, with a jwilder letsencrypt docker reverse proxy and maybe a password and bookmark server like passbolt and xbrowsersync on a little low powered device like say an intel nuc? Would love to see your take on this and most importantly how to backup data on services running in docker containers. Thanks :)

[@akistr2883]

01:17 Instant Like the moment i realize that Wendell has constructed a new technological terror .... (please mate, don't turn into Palpatine)

[@rklrkl64]

A couple of things to be wary about Proxmox and HA - live migration often isn't supported between nodes that are running different major versions of Proxmox, which is a complete pain if you're trying to avoid downtime during a major update of Proxmox. I've even had a few *minor* release differences of Proxmox fail to live migrate between them, which is even more maddening. Another HA gotcha is that Linux VMs survive only about 25 seconds without their filestore being present before it goes read only and the only way to fix it is to reboot (or power cycle if it's really bad) the VM. So your shared filestore has to also be configured for redundancy, via whatever your preferred replication method is.

[@IsraelJuliusKJ]

Useful!

[@180doman]

Some PowerShell SCM or Ansible vid? You already did chocolatey so those would be great addition. As for proxmox i use it at 2 servers on my company and as NAS at home. Ive noticed that community repositories for paid repos become more and more like Fedora is for Red Hat - testing ground for updates. So anybody who wants to try proxmox needs to drop that illusion that its for free. Because the price here is stability.

[@geoffhalsey2184]

[@chbrules]

We've just done a large AWS migration of 95% of our infrastructure, but we're aiming to buy some new stuff for the remaining services. I'm definitely trying to get the management to purchase some Epyc hardware. We've been talking about VMWare licensing again, but Proxmox looks really awesome. Quick question, does Proxmox support iSCSI targets for backend storage? If so, we might be in business!

[@LtdJorge]

Remember that VMware is changing their licenses and limiting them to 32 cores packs. So if you were to buy a 64C EPYC, you'd need 2 licenses. Tho comparing to Intel, it's still probably worth it.

[@chbrules]

@@LtdJorge That's definitely good info to know about. It's annoying companies like Microsoft and VMWare are going to a core/socket licensing model to get more bucks.

[@LtdJorge]

@@chbrules yep. And VMware products are definitely not cheap, to begin with.

[@GameCyborgCh]

could you make a video on how to setup a high availabilty cluster with replicated storage

[@carlosrc7845]

I would like to get some useful power consumption numbers... especially in idle/quasi idle status.

[@ewenchan1239]

My single application workload will DEFINITELY access and/or address 128 cores without any problems. As I've explained to my dad, in what I do, there is and there will NEVER be a shortage of cores, storage space, RAM, etc. I will always be able to suck that up and demand twice/ten/hundred/thousand times more because we just keep making our problems/cases more and more detailed. That being said - I play with Proxmox on an old HP Z420 workstation and it works great with Linux, but trying to run Windows 7 in graphical mode was dog slow. I don't have that kind of an issue when I tried Oracle's VirtualBox. Proxmox appears to be great if you're running stuff without GUIs, it can be blazing fast. But I also think that virtualization really doesn't have much of a use outside of the datacenter, and not even for SMB/SMEs. Yes, you can consolidate racks of equipment into a few servers, but this presumes that you even have racks of servers to consolidate initially. For most "normal" users, that's probably less likely to be the case. What's also less likely is that most "normal" users will have multiples of this type of server running (for HA, as described) in order to consolidate their half-dozen (or so/or more) towers into a rack server and even then, you still need a desktop to be able to log in or open up the console to be able to actually do stuff from the Proxmox virtualized compute environment. And then there's this: "Don't use ZFS. It's that simple. It was always more of a buzzword than anything else, I feel, and the licensing issues just make it a non-starter for me. The benchmarks I've seen do not make ZFS look all that great." - Linus Torvalds

[@andljoy]

Linux Torvalds has no idea what he is talking about when it comes to ZFS.

[@ewenchan1239]

@@andljoy You're more than welcome to review the benchmark results performed by Michael Larabel on his website phoronix.com. You can search for ZFS and review all of the published benchmark results there and see for yourself.

[@vonkruel]

If performance is all you care about, I wouldn't choose ZFS. If you care about certain features and reliability / data integrity, ZFS may be a fine choice. Saying that _nobody_ should use ZFS just makes you sound like a crank (even if you're Linus Torvalds).

[@ewenchan1239]

@@vonkruel In regards to reliability/data integrity - it depends on which specific feature you are referring to. If it is about data checksums, there's ZFS, Btrfs, ReFS, SquashFS that will do that (in addition to HAMMER and NOVA). If you're talking about, for example, copy-on-write, even XFS can do that (by request). Even for data reliability though, ZFS would NOT be my preferred choice because ZFS cares a LOT about the UUID that it writes to the block devices such that if you scramble its position, it WILL put the pool into a degraded state and depending on how you have set it up, it can also completely destroy your pool. Per the feedback that I received from Sun Microsystem's own kernel development engineers, it is ALWAYS recommended that you have backups (usually referring to tape backups) of your system/data when you are using ZFS because it CAN catastrohpically fail like that. And let's be real here - MOST people who are deploying ZFS in their home lab, AREN'T going to be dropping 5 grand on a LTO-8 tape drive backup system so that they can back up upto 120 TB over 10 tapes. This means that MOST people who are deploying ZFS DON'T have the most fundamental and critical element, as recommended by Sun Microsystem's own kernel development support engineers - make sure you have backup(s). From Linus' perspective, he would be right due to the licensing issue and HIS own inability to maintain due to the LEGAL differences that arise from the use of the different licenses. I would HIGHLY encourage and advise that people should read his entire comments especially given the fact that Linus references the CURRENT Google v. Oracle America case which is going to the US Supreme Court and therefore; the LAST thing that Linus would want is for Oracle to sue Linus and the Linux Foundation if Oracle wants to make a pass at COMPLETELY quashing the ENTIRE Linux OS completely. Therefore; to recapitulate: ZFS is: 1) Not the greatest for performance 2) Not the greatest for reliability (you can watch other KZbin videos of people trying/struggling to fix their zpools) 3) Most people who are playing around with deploying ZFS DON'T have the requisite data retention/backup infrastructure in place in order to be able to properly and appropriately tolerate a completely failed ZFS pool/array. 4) Oracle is highly litigious.

[@tin2001]

Windows 7 being stupidly slow is Windows Update. It got broken badly about 18 months ago and it just sucks CPU and disk IO. It does it on real hardware too, and other virtualisation systems. Server 2008 R2 does the same thing. Disabling the various Windows Update services brings it back to sane speeds..... And since there's no more updates now anyway, it doesn't make much difference.

[@omsi-fanmark]

We *had* a Proxmox setup. It was *replaced* - together with other systems and virtualisation platforms, by *XCP-ng v8,* the free XenServer alternative, full name is *Xen Cloud Platform.* And we're using AMD EPYC, currently 24-core Zen1. Our setup includes a frontend system (firewall, monitoring), 3 main server hosts in one XCP-ng Pool and a backup system. Reasons for XCP-ng: Free, fast, easy, lots of enterprise level features and high stability. More about XCP-ng here: xcp-ng.org/

[@TheLovinator]

Isn't Proxmox free, fast, easy, lots of enterprise level features and have high stability?

[@omsi-fanmark]

@@TheLovinator True, but the features are not identical. For example, both platforms can live-migrate a running VM between hosts, if they are organized in a server cluster. XCP.-ng v8 (or the Citrix equivalent, if you want to pay a lot) can do this even when local storage is involved (gets live-migrated along with the VM). Also, XCP-ng v8 supports VM migration between different pools (XCP-term for cluster).

[@rklrkl64]

@@omsi-fanmark Note that Proxmox 6 now supports live migration of VMs that use local storage, but obviously it could take a long time depending on the size of the VM and the speed of your network/disks.

[@omsi-fanmark]

@@rklrkl64 Sounds good. We are using local NVMe/U.2 storage and the first (and only) migration we needed was surprisingly fast, seemed even a bit faster than the pure network speed. May have been due to on-the-fly compression. Didnˋt notice any service slowdown either, but load wasnˋt high anyway. . Link is a single 1 GBit/s. So expected ~ 120 MB/sek.

[@blkspade23]

Having done it myself recently, I can say it works quite well performance wise. Once you get past the initial process of blacklisting so that the host isn't trying to use the device, its pretty simple to pass through, but you then lose the ability to interface with the VM in the browser. Nvidia consumer geforce gpu's are a separate problem that can be worked around. I run my test Proxmox drive headless, with an autostarting Windows VM with GPU pass through.

I'd just like to interject for a moment. What you're referring to as Level1Linux, is in fact, GNU/Level1Linux, or as I've recently taken to calling it, GNU plus Level1Linux. Level1Linux is not a youtube channel unto itself, but rather another free component of a fully functioning GNU channel made useful by the GNU corelibs, shell utilities and vital channel components comprising a full channel as defined by POSIX. Many youtube viewers watch a modified version of the GNU channel every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Level1Linux, and many of its viewers are not aware that it is basically the GNU channel, developed by the GNU Project. There really is a Level1Linux, and these people are watching it, but it is just a part of the channel they watch. Level1Linux is the kernel: the video in the channel that allocates the channel's resources to the other videos that you watch. The kernel is an essential video of a youtube channel, but useless by itself; it can only entertain in the context of a complete youtube channel. Level1Linux is normally viewed in combination with the GNU youtube channel: the whole channel is basically GNU with Level1Linux added, or GNU/Level1Linux. All the so-called Level1Linux videos are really videos of GNU/Level1Linux!
