After installing Virt-Manager on a new install which booted normally twice before performing the virt-manager install (tried this a few times) I get frozen at the BIOS splash screen.
First it will show the logo, show booting blend, show the logo and hang. It was doing the same before except it would just boot after going back to the logo
Command used was
'sudo system install qemu-desktop virt-manager virt-viewer libvirt'
