That is how a layer 3 (IP) VSWITCH works; the virtual MAC is not known by
the real network.  If you have network filters/firewalls that don't like
different hosts using the same MAC, then you need to change the VSWITCH to
be layer 2 (ETHERNET) and make any needed Linux config changes.

With a layer 2 VSWITCH you will be responsible for MAC address assignments
and so you will need to set up and manage the VMLAN MACPREFIX in SYSTEM
CONFIG.
