Re: [Xen-devel] Re: Live Migration problems using xenapi with xm

Thanks for your reply,

I'm wondering - is this uncharted territory, or has migration on HVM (with xenapi) worked in the past? We'll be happy to help fix this...but it would go a long way to know what is thought to be working.

Strangely, I have found that I can migrate guests with xenapi that were not created with xenapi.

Just as a hack, I also tried always returning True for is_hvm. This seemed to get the migration process further, but seemed to get hung up on closing(or connecting) the vkbd device - leaving the domain in a broken state at both the sender, and receiver

Thanks for investigating.

I'll continue to dig further, but if anyone has any thoughts on this, 
I'd welcome pointers.

I don't have any thoughts right now, I'm afraid.  I hope to be in a
better position to help out very shortly; There's quite a lot of
review, testing and general sorting out of XenAPI needed which I'll be
looking into.

In the meantime, good luck and do let us know what more you find.
