Code Issues Proposed changes

Trust receive filters of baremetal nodes

Browse Source 
By default libvirt does not allow traffic destined for other MAC
addresses to reach VMs when using a macvtap interface. This prevents
multicast from working.

This change fixes the issue by setting libvirt_vm_trust_guest_rx_filters
to true.
