I was using Whonix on KVM until upgrade to 14. I was all ok. Now I made fresh install according to wiki. And I get the problem with VMs start (both Gate and Workstation). Here’s error:
Error starting domain: unsupported configuration: Block I/O tuning is not available on this host
Traceback (most recent call last):

libvirtError: unsupported configuration: Block I/O tuning is not available on this host
Maybe new 14 Whonix requires some special features in the kernel of the host? What option should I enable in it?
Or maybe I have compiled qemu/libvirt without some needed flags to run new Whonix?
