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.

Most XS timeouts take place currently (at least before Hypervisor 8.0) not until passing the 24 hour mark.

As to latency, I'm not aware that there is any such restriction.

I don't remember seeing anything like that stated anywhere.
