Hi Milan The issue is that debian does not have the proper symbolic link of the kernel device /dev/vport2p1. another issue for it not to work; is that when you look at the device attributes for vport2p1 the attribute name is something else under debian stretch (ATTR{name}=="ovirt-guest-agent.0" )
So to fix it you have to create a udev rule, i placed it under /etc/udev/rules.d/10-vdsm.rules --lines-- KERNEL=="vport2p1", SYMLINK+="virtio-ports/com.redhat.rhevm.vdsm" --end-lines-- Regards, mpho raffiki
