If it's virt-manager, in the end it's something fast, maybe QEMU/KVM,
but not necessarily.

Is booting the guest already slow?
If so, then inside of the guest take a look by running

$ systemd-analyze blame

to see what actually is slow.

I wonder if it matters, when host and guest are using different window
systems, IOW one is using X11 and the other Wayland.
