Virt-Manager Tips and Tricks from a VM Junkie

Virt-Manager is a virtual machine program, and for Linux users, it's a good alternative to VirtualBox. In this video, I will share some tips and tricks that I've found useful myself, including:

► 0:00 Intro
► 2:25 Connecting USB devices
► 4:45 Cloning a VM
► 7:11 Setting up shared folders
► 16:20 Converting VirtualBox VMs to Virt Manager.

I'd really love to see videos on virt-manager networking. That topic has illuded me in trying to set it up for servers.

I'd like to to thank you for a quick run through tremendously useful information. The KVM seems lightning fast. My 1st look is that it is possibly faster than the host OS. Boxes was impossible. Virt-Manager seems to have been a well kept secret, if the name is any indication. Your vid solved a Boxes IP subnet stopper. Great work.

great video, KVM is great. I play in windows inside a qemu/kvm machine with GPU passthrough, almost with native performance, and most important never boot again windows directly in my hardware... and was easy to setup following the arch wiki article for this purpose...

[DonaldWyman]

Thanks for this. For the past few years I was using fedora and gnome so I would use boxes because it is installed out of the box(ha ha) But just recently I switched to an Arch based distro and KDE and was wondering what I could use to replace boxes and virt-manager seems to be almost the same as boxes and I tried it out for the first time last night and really liked it, so now I know a few more tricks to using it.

DT you are in my opinion the best channel for noob linux users.
BTW i am a noob learned so much from your videos and the reason i am staying on linux.

Excellent DT, thanks. I needed to find this video . Is sound in Virt Manager Guest VMs? There is in proxmox Guest VMs? Going to chk your channel to see what else you have on running Virt Manger VMs

cloning is fine if you have lots of hard drive space. are there no snapshot functions that only do the diffs in kvm? I have about 5 virtual machines and they take up nearly 120GB. my drive space isn't endless. there are plenty of other things on my drive that eat away at the storage. and I can't just allocate another 15GB just because I wanna back up my arch linux installation every time I want a snapshot.

Hi. First let me say thank you! I run fedora 37 (fedora because for me it is the only Linus distro that has never given me any problem in 3 years so far when I first installed on on a 1TB USB), and inside Fedora, because of your other helpful on how to install qemu and get it up and running, I have two VMs. Windows 10 and Kali for what I do. But I wanted to help out by reporting my discovery, since you did your part helping out showing how to even install qemu and get it up and running. I noticed that you used dolphin file manager to see where the USB was after you turned the USB on. I'm sure dolphin is probably just the default file manager in Manjaro. So I installed dolphin file manager in Kali. After two days of troubleshooting trying to figure out why my USBs would not. I installed dolphin file manager in Cali and as soon as it was done installing my USB showed write-up on the bottom dock! So if you want maybe let people know that dolphin file manager was at least my resolution and it maybe there's also.

We need more virt-manager/kvm/qemu content

[drusso]

Great informative video, just started using virtual manger in Ubuntu and have lust setup my 1st VM of MacOS Catalina, would live to be able to use my dedicated GPU but not sure how to go about this, do you have any tutorials ?

[masterofyeet]

There is one more thing, recompile qemu so that you can get a smooth experience cause qemu can't show mouse movements in a smooth manner and feels choppy. It's really unbearable having a non smooth experience even with a good iGPU.

[darthcabs]

Comprehensive content. Congrats! The only thing missing IMO is GPU passthrough

[vknp]

Interesting video reasonably new to virtmanager and KVM have used VirtualBox, Vmware and Parallels before . My 2012 i7 Macmini doesn't seem to have enough horsepower to run macOS in KVM under Linux. But of course I don't need to.
Any chance of a list of the terminal commands used in the video for my notes ?

[mandrasaptakmandal]

Hi I have a question, Is there any way we can directly enter a VirtManager Session from the Login Page like how Kodi Allows to directly Login into its session? Thanks in advance!

My VM did not mount the shared file on boot after fstab was edited. To solve this, in the VM I added a script file in /etc/network/if-up.d and made it executable (under the file's permissions tab) to execute mount -a after a 5 second sleep. The script file has the following entries:
#!/bin/sh
sleep 5;
mount -a;
exit 0;

[tilmannrueckauer]

Concerning the shared folder: How do you solve the problem that the file created on the host system by you (dt) changed owner automatically to "nobody" as soon as you edited it on the guest machine and was no longer rwx for the dt on the host machine? If you want to use files both on bare metal and on VMs, the owner should not change and the files should stay readable/writable for both sides, right?
Thank you for all your explanations in this and other videos - greatly appreciated!

[johnsnyder]

Great video!! But can you PLEASE add one more thing - how to share a folder between a Linux host and a Windows guest!!!!

[hoterychannel]

Nice thing with smb and some other is ability to mount chan specify his and gid of files. Is it possible with 9p? Some daemon that will monitor and automatically mount shared folder and deal with permissions will be great...

The problem I'm having with QEMU/Virt-Manager is I can't get Virtio opengl to work along with Spice opengl. If I turn off opengl the machine boots, but opengl on results in it sitting at a black screen for a long time and than it usually shutsdown on it's own.

[Ghstxpit]

Hello, I have install Qemu/Virt-manager in dtos and i have two menu is not present (Type and Mode 9.12min in this video) look screenshot for mount shared folder in windows10 echec permission 😒
Thank you for help 🙏
