Same MAC address in 2 different VLANs

Could any one comment about the use of the same MAC address in 2
All my machines are connected to 2 VLANs (one public and one private)
with no routing in between the VLANs.
I used to run a FLEX license manager to a physical machine. When I
virtualized that service, I had to use the MAC address of that physical
machine for the virtual machine (FLEX is linked to the MAc address and I
coul dnot issue new license as licensed the pproduct is not supported
anymore). The virtual NIC that has the old MAC address is connected to
the public VLAN.
Now I want to reuse the physical machine as a VMware server. Dell nor
VMware offer a solution to change the MAC address (like
ifconfig em0 link xx:xx:xx:xx:xx:xx would do). So I plan to connect the
NIC with the incriminated MAC to the private VLAN.
Most (if not all) my servers are FreeBSD. Most will access the virtual
machine running FLEX and may access the VMware server also. The servers
are not VLAN aware.
Will this be an issue?
