Last updated on SEPTEMBER 22, 2015

Applies to:

Oracle VM - Version 3.2.1 and later
Private Cloud Appliance - Version 2.0.1 and later
x86_64

Symptoms

On : OVM 3.2.8 version


ACTUAL BEHAVIOR
---------------
Live migration is making the VM guest server's time jump to the year 2060 in a Linux PVHVM guest, when performed from an OVM server with xen version xen-4.1.3-25.el5.94.1.4 to a server with higher version. Migration between servers with same version of xen works fine.

 

### migration kicked off

Changes

In a serverpool, one server has the the venom patch applied by referring to Doc ID 2010871.1.

The patch upgraded the xen package from xen-4.1.3-25.el5.94.1.4 to xen-4.1.3-25.el5.127.36.1.

Now, when a VM from an un-patched server is migrated to a patched server with xen-4.1.3-25.el5.127.36.1.x86_64, the date changes to the year 2060. The ntp catches up after 15-20 minutes and the date gets corrected.

This has not been observed on a  Windows VM.
