Hi folks, I hope this is the right place to ask - if not I can switch to the CentOS mailing list. I am running GITCOs 3.4.3 hypervisor with original RHEL5.5/CentOS5.5 kernels in dom0 and domU. I have phenonema I want to get rid of (like time running wild - really wild). So I am looking for a way to compile a kernel with all CentOS refinements/backports/additions and xen 3.4.3. I have googled quite a few hours but found only with posts where people asked for help in that. :-) Can someone point me to a howto? Has anyone out there already tried this? Since 3.4.3 is still focused on the 2.6.18 line of kernels this should not be impossible but I am not sure where to start. Any hint or help is appreciated.

RE: [Xen-users] CentOS dom0 and domU kernel with xen 3.4.3?
If you are having problems with the time running wild (running way too slow or way too fast) in the CentOS domUs, then you probably need to change the clock options for the kernel in the guest OS. In the CentOS guest, edit /boot/grub/grub.conf add this to end of the kernel line: divider=10 clocksource=acpi_pm That usually fixes problems with CentOS guest clocks. Good luck. -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Dirk Sent: Tuesday, October 19, 2010 8:03 AM To: xen-users Subject: [Xen-users] CentOS dom0 and domU kernel with xen 3.4.3?

Good luck.I am afraid it did not. It seems to have prolongued the interval of time working for 1 or 2 days, but it happens as before. Is there anything else I can do? By the way, the problem is also in dom0, it is not accessible serveral times a day due to timeouts during ssh login (and postfix master stopping because of watchdog timeouts etc.). Can I/must I configure dom0 similarly?
