I test XCP with native SUSE 2.6.34-xen kernel. It works almost perfect, but I do a stress-test (6 cores, 10 cpuburn copies, and high IO queue) and do infinitive loop for migration: while true: do xe vm-migrate uuid= host=host1 --live xe vm-migrate uuid= host=host2 --live done about after 500 migrations I got message "VM didn''t acknowledge the need to shutdown" and on local console was leftopvers of crash.
