Fails to grab the MAC on OpenVZ virtual server.

[powerpbx]

When this package is used on an OpenVZ virtual server with virtual interfaces it incorrectly detects venet0 as the interface for grabbing the MAC address from even though the VPS has an eth0 interface I manually create for that purpose. Since virtual interfaces venet0 and venet0:0 can not have a MAC address it fails to grab it.

ifconfig

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 127.0.0.2  netmask 255.255.255.255  broadcast 0.0.0.0

The above MAC and public IP have been changed and are not my real ones. The eth0 interface was created for this container, specifically for attaching a MAC address to, using the following command on the physical server. $VEID is the virtual server ID #.

vzctl set $VEID --netif_add eth0 --save

I would be helpful if this package was updated to ignore virtual interfaces, such as venet0 and venet0:0, and only detect MAC capable interfaces, if they exist, instead.
