How to install & use QEMU+KVM and virt-manager

[@nothingiseverperfect]

Recently learned about this, thank you for making it so simple! Thank you! And also starting the tutorial with what the end product is going to be was FANTASTIC. THANK YOU

[@iuhere]

Very Nice video. Keep them coming. One suggestion, a compliment to this video could be setting up two monitors and showing separate displays running separate OS running. Especally any game running on windows(pc) version in addition to kvm shared resources like keyboard and mouse separately. Although that might be a complex setup but many people (gamers) would love to see that counting myself in the same. Thanks for sharing this one, and good luck for the next one👍

[@Doriandotslash]

That would be interesting to see, and doable since I do have 2 monitors... But why wouldn't you just run the game in the same OS?

[@iuhere]

@@Doriandotslash FunFact because I will be working on the linux ( 😊 😉) while games I play are currently not supported on the platform(the only sin game developers commit IMO ) so windows is needed for that part. KVM removes delay/lag of input controls from games. Purelydriven by some other video I saw somewhere long time ago when I used to have hardware that did not support kvm io forwards on bios level.

[@jonathangriffin9111]

Great video. Appreciate the install walk thru and thoughts on usage.

[@AbarSimorgh]

Thank you for the video. If on openSUSE Leap (15.2 in my case at the moment) after installing virt-manager and qemu-kvm, libvirt daemon and KVM server need to be installed through YaST by doing the following: YaST > Virtualization > Install Hypervisor and Tools > tick for 'KVM Server' and tick for 'libvirt LXC daemon' then 'Accept'. Let it install then reboot. If you have NVidia installed manually you need to re-install the NVIDIA*.run file again and run mkinitrd and reboot.

[@mekuranda]

great refresher on this subject. I always have issues in copy pasting and networking between VMs and Host...I would love a simple solution if one exists

[@Doriandotslash]

Thank you. For copy and paste, you can install spice-vdagentd in the Linux distros, or spice-guest-tools in a Windows machine. Networking works pretty well between VM's as long as they're on the same virtual network, which they are by default. You can add multiple networks in virt-manager by going to Edit>Connection Details. From there you can add multiple networks to the default one and specify your own network address ranges.

[@serge5046]

@@Doriandotslash Not as easily as you think. For bridge networking, you often need bridge-utils and ebtables and you have to check in the host's terminal that the correct vibrN interfaces are there (replace N with 1 or 2 depending on the case)

[@Doriandotslash]

@@serge5046 That's odd. Because I just created 2 VM's running the Fedora 33 Live ISO, checked their IP's within the guests, and they are able to ping each other. Screenshot : ibb.co/wd0DHm6

[@serge5046]

@@Doriandotslash Try to install Slackware or Gentoo in a VM and see if the network is doing fine (doing updates and installing packages in the VM). Now by bridge networking I meant between the host and the VM not between VM's. Your case is working because you chose the default networking for the two machines which is always 192.168.122.0/24 and your two VM's are in the same default network as you can see it from this article: wiki.libvirt.org/page/VirtualNetworking I am talking about a bridge networking between the host and the VM ! I didn't see it the first time but in your screenshot the machine is pinging to itself !!!

[@Doriandotslash]

@@serge5046 You're right about the ping, my bad. Here's a new one ibb.co/XFSq42q It shows pinging between VM's as well as pinging my host IP address. Works fine in all situations. As for Gentoo or Slackware, well those are quite niche distros that you need to build, and you if you want to do something in those distros, you need to install and configure it to do so. That's the nature of them. Most other distros work fine for networking, including Arch.

[@atachualpas]

Thanks, very nice video! On my Linux-Mint the virt-manager is also in Synaptic. Performance is not so good like in VirtualBox or VMware, but its good enough to try out some things...

[@Doriandotslash]

Interesting. I get better performance in QEMU. But sometimes not as great if using Wayland so I'll enure to use Xorg.

[@atachualpas]

@@Doriandotslash For example, Hypnotix on LinuxMint as guest doesnt play video and sound synchronized, or the basic font is somehow blurry on Ubuntu-guest...Maybe it's my HW-configuration... But, otherwise it is good for experimenting.

Forgive my ignorance as I am a newbee at the virtual machine "stuff". I am using a 27" iMac (2020) that came with Catalina (64 bit) pre-installed and I am also dual booting into Windows 10 via Bootcamp. I am trying to get Mojave (32 bit) installed on it somehow with either a virtual machine (VM) or as an extra partition. I have 32 bit software that I need to use and I already tried Parallels Desktop for Mac but it keeps on crashing the software and very “laggy”, not smooth. I also tried Virtual Box but the script hangs and does not get to the installation interface for macOS. I also tried installing Ubuntu but for some reason I was unsuccessful but willing to try again. I also created a bootable USB key of Manjaro and was able to boot into it but got stuck not knowing what to do within in. I don't know much about Terminal but I can obviously follow instructions on what command lines to paste. The latest time I tried to install Mojave within Virtual Box, I received a critical error. Would your method work for me to get Mojave installed into my iMac? Do you have another video with step by step onscreen instructions? Would Thunberbolt 3 be recognized? Any feedback is appreciated.

[@dallase1]

Virtual Box is better than QEMU+KVM and virt-manager, I installed Windows 10 on it and it's way slower than it is when running in Virtual Box. With Virtual Box you can move the virtual machine image to another drive or directory. You can't share files on your host system or if you can it's not intuitive, with Virtual Box you just tell it which directories or entire partitions you want to share from your host system. I'm using Virtual Box Version 6.1.18 r142142 (Qt5.9.5)

[@AnExistanceOfNothing]

Thank you for the informative video. I've followed your instructions, but seem to have hit a snag. If you have any advice, I would appreciate your help. I tried running Windows 10 in a Virt-Manager virtual machine, but I can't seem to install the drivers for the graphics card (Nvidia 3070 Ti, if it's relevant). When I go into device manager, the card just shows up as "PCI Device". The card is being recognized on my actual computer, but I'm not sure why it's not being recognized in the VM. Is this normal? If not, is there a solution? I recently moved over from Windows to Linux (Pop OS), and thus far I've been very happy with the experience, but I must admit I was banking on a Windows VM as a safety net for anything Linux couldn't do. Either way, thank you for taking the time to read through my question, and have a nice day.

[@Doriandotslash]

You won't be able to access your Nvidia GPU directly unless you setup GPU passthrough. I know there's documentation on how to do it, but I've never had to try it myself. Otherwise you'll want to look for Windows Guest Drivers called virtio, which you will install within your Windows 10 VM.

[@paulmaydaynight9925]

what are the 'video QXL' and 'display spice' options and how do you use them ?

[@Doriandotslash]

These are the virtual display devices that your guest will see as graphics hardware. You can usually leave these alone, but if you have a guest that is having issues loading graphics, you can change this to vga or virtio to try to resolve it. I’ve only ever used virtio for a Windows guest so I could load the virtio drivers in a Windows guest but it isn’t necessary. The documentation can provide a lot of detailed information on these different modes and when to use them.

[@tacokoneko]

the epic rabbit hole behind this topic is that there is actually another option called *vfio*

how does qemu differ from virtualbox?

[@Doriandotslash]

VirtualBox is quicker to set up initially, but it is also closed source. QEMU with KVM takes advantage of better integration directly with the Linux kernel, and in my experience it yields better performance overall. I also find you can do more hardware tweaks with QEMU and virt-manager compared to VB.

Good video! Any chance you could try running virtual machines on a Fedora host? I recently tried running some VMs on Fedora 32, but the network didn't work (some problems with nftables). I don't know if that has been fixed in Fedora 33 (I have other things going on; it's not really a good time for me to do a fresh install). I'm sharing this post to let people know, and also to see if others have encountered similar problems.

[@Doriandotslash]

Thank you! Yes I have run this setup on Fedora 31,32 and I'm now running it on 33 with no issues. Your issues sounds like it might be the firewall blocking the network access. I personally never use firewalls in Linux myself, which could explain why I've never had this issue.

@@Doriandotslash Hello Dorian, thank you for you reply! Yes, it is related to the firewall (apparently it was trying to change something in nftables, but failed) Unfortunately, disabling firewalld is not something I'd want to do on my personal machine, and definitely not something I'd recommend in a professional environment using RHEL, Oracle Linux... or the late Centos (oh man, that will be great fun migrating our servers... 😆) I mean, even disabling SELinux (which, btw, is a royal pain!) is a big "no no", so disabling the firewall... 😂 😂 😂
