Hello, I have just decompressed archive and started to import Whonix VM Templates. But I’ve got an error on first step: virsh -c qemu:///system define Whonix-Gateway*.xml error: Failed to define domain from Whonix-Gateway-13.0.0.1.1.xml error: internal error unexpected feature pvspinlock
Ah OK. The libvirt version is too old to support this feature. You need to remove the pvspinlock feature from your config files completely.
You’re running Ubuntu LTS - Debian’s equivalent of old-stable but the config files target the stable version. So for best results please move to Debian stable which I recommend over Ubuntu anyway.
Ubuntu has a poor record for respecting user privacy.
