Re: [Xen-API] Live migration without access to HVM guests

[Dart Vader <dartvader@xxxxxxxxxxx>]

Hi, The live migration fails for all HVM linux machines (already tried 
with Centos 5.6 and ubuntu 11.04), seems a problem with hdd dma, on the 
console we can see that the domu loose the access to the hdd after 
migration.
btw, on the same pool, a win 2008R2 domu can do live migration without 
problems.
I cant understand, whats the difference between HVM linux and HVM 
windows ? its not the same QEMU emulation ?
Any clue ?
Thanks
