Hi Mark, I think the problem is that you are not using the CONTEXT = [ NETWORK = YES ] option. If you don't, the VM will infer its IP from the MAC, converting the last 4 bytes of the MAC to decimal:
MAC="54:52:00:c0:de:0a", => 00 . c0 . de . 0a => 0.192.222.10 If you add the CONTEXT bit from before to your template everything should work OK. cheers, Jaime On Mon, Oct 21, 2013 at 4:14 PM, Mark Kusch <mark.ku...@silpion.de> wrote: > Hi list! > > Problem solved...
