Unable to activate windows 2003 se

Hi all,

I post here because I experiment a lot of problem to activate windows 2003 server se on kvm guest. I use the latest version of kvm (88). I've tested with 2 different emulated nic (realtek 8139 and intel pro 1000) and with the intel one, impossible to go to windows update website which is not the case with the realtek but I'm unable to activate windows anymore...

Does anyone have already has similar problem ???

Regards,
