Default Bug#619317: linux-image-2.6.32-5-xen-686: booting via hypervisor slows bootup significant (hang) and also slow on runtime

It looks like “max_cstate=1″ did fix the problem for me. It also appeared
recently on the Linux power management list[1]. In the next day I will also
try "hpet=disable" and give feedback.

With kind regards, Jan.

Okay .... "hpet=disable" seems not to work, while "cpuidle=off" did work also
quite well instead of “max_cstate=1″.

I experienced the same on a recent HP DL108 G6 with linux-image-2.6.32-5-xen-
amd64.
Even with “max_cstate=1" it seems to have slowness on disc access compared to
running without hypervisor, but thats just empirical.

With kind regards, Jan.
