If I understood corectly, the VM cannot ping the gw/pc even without vlans
in place.
Do you have mutiple macs on the VM itself? (like a bridge or some sub
interfaces)
The only thing that comes to my mind is the mac-spoofing that is enabled by
default,
it restricts the VM from using more than one mac address to communicate
through a
vnic.
Except that, I do not have a good idea on what may be wrong.
Your best friend is tcpdump, make sure you do not see any vlan/tagged
packets on
the bridge. (if a tagged packet enters from eno5, it will pass to the
bridge as is, even
passed to the vtap as is... the VM will drop it as it does not expect a tag
there)
