Hi there ...

I'm new to openvz, therefore I apologize if my question is simple.

I'd like to use openvz to run several small services on a big
server. As fas as I read, openvz is just the right way to do that.

My question is this: Among the 'small services' there will be at
least two different license managers which check the MAC address
of the nics to confirm they are running on the 'correct' server.

Which MAC addresses are used inside the VE's? The real MAC add-
resses or some virtual addresses?

Thomas

you can grant some ethX device exclusively to VE,
in this case it will be real MAC.

or you can create veth adapter with whatever MAC you want.

Thanks,
Kirill

Is it possible to re-use the real MAC on a virtual adapter,
or does that (read: "can eventually") cause problems?

if you don't put then real adapter and virtual one in the same bridge -
no conflicts will happen.

Thanks,
