Re: [libvirt] libvirt passes wrong MAC address to KVM
hmmm, I'm sorry, it was my fault, stupid mistake in one of scripts :( so it was false alert, libvirt is innocent... sorry for inconvenience...

[libvirt] libvirt passes wrong MAC address to KVM
Hi all, I think there could be a bug in libvirt passing MAC address to KVM. If I have following in my xml config: interface type=bridge source bridge=br0/ mac address=00:16:3e:0d:24:00/ /interface and start the domain (I'm using python binding btw), qemu is then executed with following parameter: ... -net nic,macaddr=00:16:3e:18:24:00,vlan=0 ... MAC address given in config is not used by any other machine. Does somebody have a tip on where the problem could be? I'm using libvirt-0.4.3.
