+static char *
+openvzGenerateMac(void)
+{
+    char mac[6] = {
+        0x52,
+        0x54,
+        0x00,
How did you get 0x52, 0x54, 0x00?

+    if (net->type == VIR_DOMAIN_NET_TYPE_BRIDGE) {
+        static int vnetNo = 0;

Libvirt may be use as library in applications. If some will call create 
2 containers, then first container will have eth0...ethN
second will have ethN+1...

Other looks good.
