You'll find that you have to recreate the initrd, else it won't boot
(I'm assuming this is a Linux guest).
This is somewhat complicated and involves running some commands from
the guest. Here's what virt-v2v does, although virt-v2v is especially
complicated because it supports doing this for everything back to RHEL 3(!)
You probably only need to run dracut if you only care about modern
Fedora & RHEL.

Yeah the target dev names in libvirt XML aren't really arbitrary
strings. Device names are controlled by the *guest* kernel, nothing
to do with the host which just exports one or another PCI device.
