<br>
Which is it? KVM, QEMU, or Xen? They each use different config files.<br>
Do you have libvirt or are the VMs started 100% from a script with all settings<br>
forced?<br>
<br>
The VM settings control which MAC addresses are passed into a VM. Make certain<br>
none on the same LAN segment conflict. Then inside the VM, you can tell the OS<br>
which to use in the udev-rules. I can help on Ubuntu servers and expect Debian<br>
to be similar. RHEL networking is different, I think.<br>
