Re: [Xen-devel] Live Migration Error

Teemu saves the day!!!
I actually set the timeout to 100 for no particular reason (originally it was 10, 20 didn't work either)
Thanks Ian for your suggestion as well

I try to do a live migration in the same physical host, i.e. xm migrate --live 'whatever' localhost
It fails with 'Error: errors: suspend, failed, Callbak timed out'.
It seems like transfer of memory pages works until the point when the domain needs to be suspended to do the final transfer. Funny thing is it used to work before, gloriously, and I haven't made any software/hardware changes. At some point a xm save command failed with timeout, and from there on live migration fails with this message. Non-live migration works perfectly, also between different physical hosts. save/restore also works flawlessly.

I had similar timeout errors previously, when I was using a bit slower servers. I overcame the problem by slightly increasing the timeout value in controller.py. It seemed to provide a remedy.
