migration of a running VM takes forever

[mgabriel]

Hi,

on a Proxmox 2.2 Cluster with a shared storage, I recently had some online migrations failing. The migration seems to run forever and the amount of data-to-be-transferred goes down and up again. I stopped it after 40 mins. A second try was successful. I had that on several VMs, but I can't figure out when or why it happens.



On the screenshot, you can see the values going down and up again.

Thanks,
Marco

Was the VM having a lot of IO at the time?

Not that we were aware of it. We looked into it, but couldn't see any load (which does not mean, that it didn't have much I/O...).
