How much delay can a migration of a virtual machine handle before it cancels out in XenServer 7.0?

Pavel Frants


I am currently conducting a experiment where I migrate the compute resources of a virtual machine between two XenServers (7.0) over a gigabit ethernet link. The virtual machine is located on a shared storage and the management network is separated from the "migration" network. I am trying to find out the limitations of the migration technology in Xen but I can't find any material on that topic. I know that vMotion in VMware requires that the round-trip time latency is 150 milliseconds or less, between hosts. Is there any similar information available about the migration technology for XenServers?


I have a virtual machine that is currently migrating over a network that has 2000 delay but it keeps going for hours.
