Re: [libvirt] libvirt passes wrong MAC address to KVM

Hum, I can't really reproduce this. I used a definition like: <interface type='network'> <mac address='00:16:3e:0d:24:00'/> <source network='default'/> <target dev='vnet0'/> </interface> since i don't have bridging set. When starting the guest with 0.4.2 I see /usr/bin/qemu-kvm -M pc -m 512 -smp 1 -monitor pty -boot c -hda /virt/test-mac.img -net nic,macaddr=00:16:3e:0d:24:00,vlan=0 -net tap,fd=14,script=,vlan=0,ifname=vnet0 -usb -vnc 127.0.0.1:0 -k en-us when starting with 0.4.3 I see /usr/bin/qemu-kvm -S -M pc -m 512 -smp 1 -name test-mac -monitor pty -boot c -drive file=/virt/test-mac.img,if=ide,index=0,boot=on -drive file=,if=ide,media=cdrom,index=2 -net nic,macaddr=00:16:3e:0d:24:00,vlan=0 -net tap,fd=13,script=,vlan=0,ifname=vnet0 -serial none -parallel none -usb -vnc 127.0.0.1:0 -k en-us but in both cases the MAC parsing looks correct and properly provided down to qemu-kvm . Could you double check with virsh directly (though i don't see how python could scramble just that part of the XML description) using virsh dumpxml and virsh create ... Also testing with a network type of setting may help finding what is happening precisely here thanks, Daniel -- Red Hat Virtualization group http://redhat.com/virtualization/ Daniel Veillard | virtualization library http://libvirt.org/ veillard(a)redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/
