Yes, the guest "virtual hardware" NIC has the same MAC address as
you've configured in the VM manifest.

However, on OpenSolaris and later, the *host* should provide a
VNIC with the same MAC address as the bridging interface. Of course
this means a host VNIC per virtual-HW NIC.

Solaris 10 did not have VNICs and yet VirtualBox works there, maybe
in the same mode you've had on your system. In my experience however,
under Solaris 10 with "improper" bridging over the native NIC it was
much more stable than in OSol in the same mode - the latter was quite
glitchy in a manner similar to yours: connectivity seemed to mostly
work on the first glance, but went out of hand relatively quickly.

That would indeed be a bug, multiple IP address aliases on the guest
should work (considering they are in the same VLAN/subnet).

I think misconfig - dedicate VNICs on the host to each VM and see
if it helps at least.
