I have a host with a Linux Bond that I use for inband management and guest traffic. I have a Linux VLAN interface as part of the bridge which I use to access the host. All is well with this part of the config and everything works as expected.
The trouble starts when I have a guest that I want to run on the same VLAN as the host's Linux VLAN interface (VLAN 15). The guest cannot communicate across the bridge at all when a tag of 15 is applied to its VirtIO NIC. PCAPs from the guest show zero traffic coming in.

Code:
root@Ghost:~# cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
