I tried using virt-manager+kvm to try some stuff out the other day but I failed to set-up some crucial things. Probably me being incompetent.

Not like virtualization is a big part of my life anyway. I just wanted to try some other distros and such without rebooting.

If I were to get serious about virtualization I'd need to build a new PC with a second GPU. Then I could stop dual-booting and do everything with VMs. But it'd only be worth it to get serious about learning how to virtualize stuff if I were to do that.

Currently virt-manager on top of qemu/kvm on Debian 12. It was the easiest to get to emulate a TPM on my ancient hardware (9ish years old, but still powerful).

I'm learning enough about the backend that I'm hoping to get off the Redhat maintained software and only use the qemu cli, maybe write my own monitor with rust-vmm when I learn enough rust to do so.

xcp-ng. except now everything is just containers on atomic fedora because it seems to fit my laziness better and doesn't require updating multiple vm os's

If I'm running another Linux distro that will be happy under the host kernel then I use LXD (or Incus) containers. Otherwise it's QEMU+KVM or occasionally Virtual Box.

Replied to others with this but realized you won't get those notifications. I finally got around to releasing this, which is Debian in your browser via Docker: https://nowsci.com/webbian
