Updated… this now uses volume groups for the disk storage, virtio for both disk and network. Created by Fedora 13.
There seem to be a real lack of decent xml examples for libvirt/kvm/qemu on the internet for people using it in a bit more of an infrastructury way (where you want to be able to access the consoles remotely using VNC) and to run windows virtual machines.
This example is a dump that doesn’t include a uuid or mac address, they will be automatically generated by libvirt.
Use
sudo virsh define dc1.vc.example.com.xml
or similar to install it.
More useful virsh commands:
virsh list --all show all VMs, running or not virsh start start a VM virsh shutdown shutdown a VM virsh edit edit the config for a VM virsh dumpxml dump the xml config for a VM virsh define create a VM without starting it virsh undefine undefine a VM
