Hi. Since I updated Xen from version 3.3.1 to 3.4.1 I can't live migrate the hvm guests. The command "xm migrate --live" finishes with the following error:
     Error: (107, 'Transport endpoint is not connected')

In the xend.log file in target host appears:

The live migration with pv guests works without problems.
My installation is: CentOS 5.4 and Xen updated to 3.4.1 via gitco repo. The hvm guest have installed GPLPV drivers, but I have tried boot with option /NOGPLPV and produce the same result.

It looks like a memory problem. Why?
Anybody have this configuration and can migrate hvm guests?
