Virt-Manager Tips and Tricks from a VM Junkie

I can’t get a VM to install. First thing it wants is “existing OS root directory”. I don’t know what I’m supposed to use.

I can't get my virt manager to work; I can create virtual drives but the play, pause and stop buttons are blocked running Linux Mint

I hate virt-manager.

👍 Have you any idea what this video just did for me? I'm going to use this info to learn scripting to customize a distro install!

Now please show how to play r6s on vm. I've done it, its just the anti-cheat you gotta pass.

How about converting Hyper-V files?

I never realized just how crappy VMWare and VirtualBox were until being amazed by QEMU/KVM/Virt-Manager.

Thanks for the video, i have a question, how to make a VM to automatically adapt the screen resolution to the windows size like virtualbox ? Thanks! (Linux as host and linux and windows as guest)

Thanks DT - worked 4 me😀

Thank you for the video.
Please, how do I remove the installed OS and regain my disk space?

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.

Why not use Qemu and make s simple script?

how do you pass in a gpu?

Am I the only one who keeps getting "no bootable media " if they reboot ? It's the opposite of the problem I've had with virtualbox

sound of the mechanical keyboard is irritating...

Can you make a video on any Trips and Tricks for Windows 10 guest machine ?, I use EndeavourOS as my primary driver and for some office software which is windows based i use Windows 10 VM in Virt-Manager, I would love to use the share folder thing you showed in Win guest and any other trips which can make my virt-manager windows experience better.

edit - I am a total newbie to Linux world just shift from Windows, 9months back, you videos have been very helpful in my transition many thanks for that.

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 🙏

Is it possible to delete multiple VMs?

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.

Trying to get a wireless card to bridge with virt-manager, so I can see my entire neywork. Can you explain that please?.

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

How do I backup Qemu virtual machines so I can transfer them to another computer?

But how about windows? How to share files between linux host and windows guest machines?

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 ?

We need a clipboard / From my desktop to my Virt desktop - cut / copy / paste

My USB devices won't redirect on my Windows VM, but it works fine on Linux VM. Any idea what I could be missing?

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 ?

I played with virt-manager yesterday for first time. Just as easy to use as Virtualbox and vmware, I find. Plus it's kvm, so faster. I'm ditching vmware and virtualbox.

I have windows on virt manager in a linux but the windows in virt manager is super slow, help needed any tips might be helpful(except for uninstalling windows).

In virtual box under Windows it is allways necessary to install vm additions (drivers for the guest os to the vm-hardware). Under KVM Virt-Manager I often find no additional drivers - are them not necessary for e.g. Manjaro as vm in virt-manager?

Why clone your virtual machines when virt manager has snapshots?

Is Virt Manager a better alternative to gnome boxes?

Who has noticed easter egg - Space Odyssey mp4 file?

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.

Thanks for another great video DT!

How do I pass my SDCard to my Virt-Manager vm?

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.

virtual knowledge achieved...

Wow, I've waited for this video, thanks

I have a windows host. I mostly use QEMU via command line or batch file. It works great.

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!

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...

For Windows users, Hyper-V is better for testing Linux distributions

DT says its a long comand.
Me imagining 5 lines worth of typing.
Then its just a bit of complicated flags.

Make a video on btrfs and snapshot ..... And reletive information nedded for that ....

Only thing I found weak or hard to do with Virt-Manager is networking. Even running bridges can bring up a bunch of problems. I ended switching back to Virtualbox as I don't care to spend all day just getting the networking for my VM boxes working properly. Outside of that I would agree it is, inherently, the better VM solution.
