oh maybe. i get vmware and virtualbox mixed up. i prefer something like qemu+virt-manager or use gnome boxes for a quick and easy vm setup, but that wouldn't fit the needs of others im sure lol
qemu/virt-manager is what we support, virtualbox and anything that needs a custom kernel driver/module for virtualization is not supported bazzite has a command to set it up and even a vfio command that configures the host for vfio (minus binding the card and doing the passthrough and prepping the card as that is your job and not something we can support, but we can at least do the system prep for you so you can just config it from there)
last time i checked it's difficult to run Windows 11 on it, but Windows 10 can work with the ISO. performance isn't great as expected and it's difficult to probably get a lot of stuff done in it, but it does work and it's really easy to install and use
