Well when I try to use the create command I get this:
virsh # create /etc/libvirt/qemu/ubuntuTest.xml
error: Failed to create domain from /etc/libvirt/qemu/ubuntuTest.xml
error: unknown OS type hvm
and I'm using virt-install by using the below command:
self.runCommand("virt-install --hvm --name " + name + " --ram " + ram + "
--file " + filename + " --file-size " + hardDriveSize + " --network bridge:br0
--cdrom " + cdrom + " --accelerate --noautoconsole --vnc")
I'm not sure if there is some where everyone keep scripts they write but for
now I'm putting them on my Wiki here:
They are not the best scripts but they are are written in python and it calls
os.system(command) to run stuff on the command line.
http://software.digisoftinc.org/DigiSoftWiki/index.php/Python_Programming_Notes#Virtualization
It is all text based and requires the Linux.py class here:
http://software.digisoftinc.org/DigiSoftWiki/index.php/Python_Programming_Notes#Linux.py
To run these scripts:
1) switch to root
2) download both scripts
3) change Virtualizaiton class to executable
4) run script
Example
#> su -
<enter root password>
#> chmod +x Virtualization.py
#> ./Virtualization.py
Let me know if you need any further info.

Subject: Re: KVM failover to another KVM server
I believe you do so the hypervisor knows about the domain.
You can use the 'create' command this. See virsh help create
