According to doc
In some google guides i found that following steps are needed in addition .
Edit libvirtd configuration file to add group
Open the file /etc/libvirt/libvirtd.conf for editing.
sudo vim /etc/libvirt/libvirtd.conf
Set the UNIX domain socket group ownership to libvirt, (around line 85)
unix_sock_group = “libvirt”
Set the UNIX socket permissions for the R/W socket (around line 102)
unix_sock_rw_perms = “0770”
Restart libvirt daemon after making the change.
sudo systemctl restart libvirtd.service
Why are these steps not mentioned in Whonix documentation ?
