I found what it was: there were some incomplete virtual machine configuration files in /etc/xen which I'd generated for testing previously. Because they weren't complete and their IDs weren't attached to any actual VM, they were screwing up any calls to virDomainLookupByName() . Removing them did the trick.
Hope this helps somebody.

Sorry to bump my own thread, but does anyone have any ideas about this?
I've now tried virtually every combination of options in virt-manager and virt-install, and nothing seems to avoid this error (or let me get beyond the networking screen in virt-manager).
Has anyone encountered anything like this before?
Thanks,
Graeme

Hi there,
I've been happily installing VMs in CentOS 5.2's Xen implementation using virt-manager. However, my latest attempt to use the install wizard in virt-manager failed when I got to the networking screen. The 'forward' button was unresponsive, and I was unable to proceed. I checked the virt-manager logs, and saw this appearing immediately after I tried to proceed:
/root/.virt-manager/virt-manager.log:

if ret is None:raise libvirtError('virDomainLookupByName() failed', conn=self)
libvirtError: virDomainLookupByName() failed got unknown HTTP error code 400
None
There was also a lot of this in the main system log (1-2 messages per second):
[Tue, 05 Aug 2008 16:16:53 virt-manager 20637] DEBUG (connection:580) Couldn't fetch domain id 3; it probably went away
So I tried to use virt-install on the shell instead, but got much the same error:
[root at optimus swadmin]# virt-install --hvm --name=zurich.gcal.ac.uk --ram=2048 --file=/var/lib/xen/images/zurich.gcal.ac.uk.img --vnc --vcpus=2 --cdrom=/home/swadmin/software/OpenSolaris/sol-nv-b93-x86-dvd.iso --network=bridge:xenbr0

Domain installation may not have been
successful. If it was, you can restart your domain
by running 'virsh start zurich.gcal.ac.uk'; otherwise, please
restart your installation.

if ret is None:raise libvirtError('virDomainLookupByName() failed', conn=self)

It suggests I try to start the domain anyway, but it hasn't been created:
[root at optimus swadmin]# virsh start zurich.gcal.ac.uk
libvir: Xen error : Domain not found: xenUnifiedDomainLookupByName
error: failed to get domain 'zurich.gcal.ac.uk'
Any ideas would be much appreciated.
Thanks,
