You can't reuse the host that easily. I believe removing acs common/agent packages and then installing again and trying to add the host again to Acs should work.
Alternate: Since it seems like you are playing in test env - remove libvirt/qemu, remove all leftover configuration files (i.e /etc/libvirt/ and so on) and reinstall everything. This brings new/clean libvirt config and should allow you to start it. Cheers On Wed, 8 Apr 2020, 16:07 Jevgeni Zolotarjov, <j.zolotar...@gmail.com> wrote: > That was it.
