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

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

Thank you very much for this video! I really appreciate how much detail you go into and your teaching style is very straightforward and easy to understand. Also want to thank you as a low vision person for using large font sizes whenever you have the terminal up!

Excellent tutorial thanks Dorian!! I've been wanting to do this for a long time, you've inspired me.!!

Thank you so much for your very comprehensive and in depth tutorial. What I really needed for setting up access to the USB and other settings. God bless you for your kind help.✝😇

Thank you buddy! you made it simple, easy, clear... I've seen lots of ways to do this there out, and 😤I don't know why they complicate too much such simple process. Awesome video! ✌🤗

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

Good Video! Very informative and hope you are doing well. (Also, Merry Christmas).

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👍

Very enlightful, Thanks!

Excellent!! Thanks so much!

Nice video! Thanks.

very good video! thank you!

Thank you, worked for me on POP-OS!

Don't have words to thank this guy. I am extremely thankful, sending you my best wishes from Bharat! :)

Thank you for the video! I like very much Virt-manager.

Thank you!

I did it! thanks to You Thanks

Thank You!

Thanks, the best ! 👊😁

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...

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.

you help me thnx U ... it work

thanks bro :)

Great video Dorian...Many thanks...I can't seem to get drag and drop working, but I can redirect my external USB SSD recognized by virt. goodbye rubbish buggy Virtualbox

Note: qemu-kvm is no longer mantained and everything is now in the mainline qemu package

Watched PCTLC video on Vitr-Manager and he suggested that we ( I ) should come over and watch you video too! Liked the video and I watched a few others so i decided to Sub to your channel... :-) Thanks for the video! LLAP

use KSM also for memory deduplication.

Thanks a lot this is the first time I understand how to install KVM ❤, Q : how I can switch between Wayland and X11 (xorg). 😊

Any guides on getting to the beginning of your video? Ubuntu install? Arch?

Nice video! What about Gnome Boxes, does it use qemu/kvm as well?

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

FANTASTIC VIDEO !!!

Worked just fine and dandy for me! thxs. hardware: HP Pavillion 13, 8g ram, Intel Core i3-8145U dual core 4 threads, Host Linux Mint 20.3 and Kernel 5.4.0-94-generic

Is this your daily driver? Looks like a clean install lol don't you customize?

Thanks for making this video! Even in the initial blender video you demo-ed that screen tearing between 0:05 and 0:06 is something ive never been able to fix whoch is preventing me from going to linux full time. Anyone know if thats fixable atall? On nvidia btw

I'm on DSL and whenever I trying to use apt-get to install these packages, it says it couldn't them. I assume I need to add another repo to fix that? (I also understand I probably won't be able to use virtual manager, I just want to get QEMU going.)

👍👍👍🙂

Thanks for this Video. I need help with assigning multiple Network interfaces for OpnSense in a VM. The Host is Linux Mint. I have 6 discrete network cards, and I'd like to assign 5 of them to the Opnsense VM as a Bridge/Switch so it can run as a Firewall/Router. I know how to configure the Bridge once the network cards are available to the VM. Any help would be appreciated.

How do I add an existing HD to kvm so I can share files between host and the guest machine? I have been looking for a video but can't find any. Would appreciate guidance. Thanks.

I hated trying to get USB devices to work in Virtualbox, I'm considering QEMU+KVM so I hope it's easier.

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.

hi, my computer is x86-64, i want to use qemu to install centos7.9-aarch64. i have failed many times. can you give me some help?

I do have a SteamDeck (Arch based distro) and after instalation I do have only LXD in the Virt-Manager but not Qemu. I tried to install the Qemu with this command: > sudo pacman -S qemu virt-manager libvirt libvirt-openrc dnsmasq virt-viewer vde2 bridge-utils ebtables libguestfs openbsd-netcat but I do get an error: target not found: libvirt-openrc

Please tell me how to run KVM after reboot main machine automatic and also OS which is installed in KVM I am going to install RHEL 6.4

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.

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)

i am getting this error while starting the vm Unable to connect to libvirt lxc:///. Failed to connect socket to '/var/run/libvirt/virtlxcd-sock': No such file or directory

Hello Sir, im using arm64 ubuntu 20.04, do you think is possible to use QEMU+KVM and use windows 10?

i do not have access to virt-manger, i am running on MX linux 21 haw can i get virt-manager ?

Using 2020 Apple MacBook Air with the new M1 Chip running MacOS 12.4 Monterey. Is it possible to install and run virt-manager 4.0.0 on MacBook with the new Apple M1 chip?

when installing it say "Note, selecting 'qemu-system-x86' instead of 'qemu-kvm'". And when i try to create a new vm it has a warning saying kvm is not available

Could you do a review of Linux computers? I want to buy one but I don't know what to buy. I think this will be a great idea for your next video! 💻🖥😀💡

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

I am having an error unable to connect to libvert lxc:///. failed to connect to socket ......no such directory . please help

thanks!

Worked :D

I am running ARM64 Debian 10 and when I opened virt-manager, it shows LXC and not QEMU. How do I fix this? When I try to install qemu-kvm, it says the package is not available.

I am getting the error unable to locate package virt-manger. It would be great if you can help, I am running on Ubuntu 18.04 version

Can i do this on userland proot on android

How can i open file .qcow2 with converted from .ova , i need help

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.

Don't forget to chmod +x before you #dotslash

unable to complete install: cannot access storage file '/media/mike/savehere/machine/ubuntu.qcow2 that's the error i'm getting when creating a new vm. do you know what can be done?

OpenSuse is also virt-manager

Mine show an error "Unable to complete install: 'missing target information for device /var/lib/libvirt/images/win7.qcow2'"

@DorianDotSlash Hi, Dorian I just started using QEMU + KVM + Virt Manager, and I like it. But the Big Buck Bunny video stutters on my VM even in 1440p... Two questions... 1 - How do you increase the video memory, because 16 MB is way to little. I know how to get it to 256 MB in VirtualBox, but did not yet figure out how to do it in QEMU + KVM + Virt Manager 2 - How do you get it to run the Guest OS in 4K resolution? My monitors are 4K UHD with 60 Hz refresh Thanks. Anybody else here is free to answer...

issue, guest has not initialized the display yet,whats the solution😁

how does qemu differ from virtualbox?

you can use `sudo systemctl restart libvirtd` and you wouldnt need to restart your pc

why do i get LXC in virt manager instead of QEMU/KVM?

I can't get my iso to boot at all.

You have to type in kvm.

Debian on your machines is no more then? :(

Not bad to run QEMU/KVM/Virt Man. But if you are serious about it, rather install Proxmox on a separate machine.

the emulator may not have search permissons for the path 5:18

GPU acceleration?

That was just an hell of requirements for me, way more than the YT video shows (everything is perfect on videos !). Virt manager is not so helpful.

0:00 OMG HE IS TESTING BIG CHUNGUS!!!!!!!
