If I want to continue to use NTP, what are the recommendations?
Probably a kernel or hypervisor bug. If these are SLES systems, please
report (with full versions etc) to NTS, but has little to do with HA.
Hi!
I think "Xen live migration" and "correct time" has a lot to do with HA; maybe
not with the product you have in mind, but with the concept in general.
For the problem: I'll retry soo with all the current updates being installed.

Ulrich

Hi,
should it be not best practice to not use a the hardware clock in any
virtualized environment. I would strongly suggest to use an external
time source.
