Using more processors, the VM just freezes (can't access from console or network) or lose Disk IO and Network connection.
I've tried the kernel http://
I'm using XenServer 5.6 Build 31188p
I'm trying to use some old kernels and backporting some patches from the 2.6.33 but I'm not successful.
I'm gonna still try to fix it, but any help will be appreciated.

Testing the PPA's kernel, before http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v2.6.32. 16.5-lucid/ it works well, after this release 2.6.32.16.5 the problem appears.
Looking at the changes, this one seems to be related, changing the disk and network, both symptoms that I'm getting:
xen: avoid allocation causing potential swap activity on the resume path
I tried to rollback the patch and the Ubuntu VM Guest gets powered off in the end of the migration.
I'll keep looking.
