There is a referenece for possible XML options here: http://libvirt.org/formatdomain.html And some specific XML examples for QEMU: http://libvirt.org/drvqemu.html > > actually with the above command a proper tapN interface is created upon > VM startup via /etc/qemu-ifup script When using libvirt, there's no need for a ifup script, since libvirt will create the TAP device and add it to the bridge for you. There is a introduction to networking with libvirt here: http://wiki.libvirt.org/page/Networking To help you get started, to replicate your example config here: qemu-kvm -nographic -hda ./abbone.img -m 512 -net nic,model=e1000,macaddr=00:16:3e:05:00:07 -net tap -name abbone -vnc :0 You would want to create an XML doc that looks like this: <domain type='kvm'> <name>abbone</name> <memory>524288</memory> <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='disk'> <source file='/path/to/abbone.img'/> <target dev='hda' bus='ide'/> </disk> <interface type='bridge'> <source bridge='br0'/> <mac address='00:16:3e:05:00:07'/> <model type='e1000'/> </interface> </devices> </domain> DOn't forget to change 'br0' to whatever bridge you are using, and set the correct path to your abbone.img disk image One thing that's confusing is that you have set '-nographic' and '-vnc' which doesn't make sense. Either you want graphics or you dont ! If you want VNC graphics, then in the <devices> section of the XML also add <graphics type='vnc' port='5900'/> Then load the config into libvirt using virsh define /path/to/config.xml And you can start it with virsh start If you have more libvirt questions, you might wish to ask on the libvirt mailing list http://www.redhat.com/mailman/listinfo/libvir-list Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
