Hi all,
I'm having issue with my Centos 5.1 /Xen installation. I'm having 2 dom0 running 2.6.18-53.1.4.el5xen (x86_64). These two dom0 are connected to a SAN. These two dom0 hosts multiple domU like Centos 4.5 (2.6.9-55.0.9.ELxenU) and Centos 5.1 (2.6.18-53.1.4.el5xen). These two dom0 run ntpd to synchronize dom0 time. When i start a virtual machine on the first dom0 all seems good, the domU time is like the dom0 time. The problem appears when i migrate the domU to another dom0. After the migration, the time in domU on the new dom0 is totally false (we can have more than one day of desynchronisation) and the time on the domU seems to be blocked (the clock indicates always the same time ). In the xend Logs we can't see any error message with the debug mode.
The solution for this moment is to restart the domU in the new dom0 to be synchronized again. We manage a lot of authentications services like CAS or Shibboleth which uses timestamp for security validation and this problem is very annoying for us.
Anyone has encountered this problem ? Any idea how to solve it ?
Thanks for your help.
Regards
Fred
