Error when importing the Workstation

Hi, I’m trying to switch from Virtualbox to KVM. The Gateway is running well but when I try to import the Workstation with:

virsh -c qemu:///system define Whonix-Workstation*.xml

Here is the error I see:

error: Failed to define domain from Whonix-Workstation-XFCE-
error: unsupported configuration: unknown codec type ‘output’

qemu-kvm 1:2.8+dfsg-6+deb9u8
virt-manager 1:1.4.0-5

Yes here’s the problem. This feature for disabling VM microphones is only availabl in Debian 10.

You will need to either migrate to Debian stable current or remove this setting from the XML. Please read the wiki for instructions for config editing.
