There is no problem regarding storage or anything like that. If I shut
down the vm I can start it on the other host without any problems
whatsoever.
Do I need to do something to make live migration work? Trying to dig in
the logs on the hypervisors, but there's so much stuff being logged there...

vdsm log from the host that failed to create the VM?

The vdsm log is frighteningly long, so I put it in pastebin: http://pastebin.com/BEeqFCCb
I don't really see anything worthwhile myself, but on the other hand I'm not sure what I'm looking for, so it's mostly a massive wall of text to me, but it should be somewhere in that time frame.
Here is the failure, "code 9" is not too informative, can you attach the libvirtd.log file too?

Thread-49287::DEBUG::2012-04-17 14:25:39,834::clientIF::81::vds::(wrapper) return migrationCreate with {'status': {'message': 'Error creating the requested virtual machine', 'code': 9}}

I think this is the relevant info from the libvirt.log:
2012-04-17 14:30:53.768+0000: 8506: debug : virDomainLookupByUUIDString:1984 : conn=0x7fa9a00bcde0, uuidstr=ce9bb531-4d2a-4f5e-9935-3c8a4f5db94a

What domain is this, is it the storage domain?

Domain in libvirt is simply a vm.

Alright, so what does this mean then? The machine I'm migrating to can't see the vm?
That doesn't make sense since I can manually start it on that host..
