In another thread I explained I took different approaches in installing virt-manager in slackware64 14.1.
Both approaches lead to the same errors.
1. Adding a connection
2. creating a VM
#1 results in
Error launching connect dialog: GDBus.Error
rg.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Avahi was not provided by any .service files
After stepping through the install options #2 results
Unable to complete install: 'Controller 'devices' is not wanted, but 'cpu' is co-mounted: Invalid argument'in
I have no clue where to start looking.
