We should be careful here. I think porting guests among "HVM" type
hypervisors is likely to be relatively easy compared with moving a PV
Xen guest to another hypervisor (which would require switching it to
HVM). People in glass houses etc...

I'm not sure this is the sort of "lockin" Russ was referring too though.
