i have a weird problem. I have a vm (KVM) which seems to run fine.

As you see, the vm has one NIC. Its MAC-Address is:
'52:54:00:37:92:03'.
I also see that MAC when i edit the config via virsh.
But when i boot that vm, it has a nic with another MAC: '52:54:00:37:92:B2' ???
Looks like the domain configuration has been changed while it
was already running: the inactive configuration contains the
new MAC address, but the live configuration still contains the
previous value.
Example:
$ sudo virsh dumpxml test | grep '<mac'
<mac address='52:54:00:e9:0a:e1'/>
$ sudo virsh dumpxml --inactive test | grep '<mac'
<mac address='52:54:00:e9:0a:5f'/>
Destroying the domain and starting it up again should be
enough for it to pick up the new MAC address.
Cheers.
PS: You should never look at the on-disk domain XML directly as
it's owned by the deamon; always use 'virsh edit', 'virsh
dumpxml' etc. to inspect and modify it.
