Re: [libvirt] [PATCH v14] support offline migration

+1 to support adding offline migration API in libvirt, for my knowledge there were multiple higher management stack in product did a couple of operations with delete/define to archieve this goal, but with those fragment operation, higher management need pay more attention and low level knowledge to handle the exception, which should be hidden by lower API. Pls keep the API unified with online migration, and enhance its error reporting function as much as possible, so that upper level stack can report what is wrong to end user. -- Best Regards Wenchao Xia
