snažím se rozchodit KVM a chtěl bych použít virt-manager. Zkoušel jsem ArchLinux 3.6 i Centos 7.3 ale zatím bez úspěchu.
Naistaluju qemu, dokonce i spustím image pomocí konfiguračního souboru. Když ale zkouším virt-amanger (po nainstalování všech dependencies, pro Centos viz KB KVM / Centos), tak virt-manager padá s nic neříkající chybou. Kompletní debug:

Vypadá to, že na něco nedostane odpověď "ret is None" .... ale netuším na co.
