[Xen-devel] [Bug 1759] Xen 4.0.1 live migration/restore over-writes new hypervisor's boot-time record

[Tim M <bugs@xxxxxxxxxxxxxx>]

It was suggested that I submit this to xen-devel in addition to the bug report.


I am having the exact problem described in bug 1282. The RedHat 5 errata for
Xen 3 describes the problem nicely so I will quote it:

xen calculates its running time by adding the hypervisor's up-time to the
hypervisor's boot-time record. In live migrations of para-virtualized
guests, however, the guest would over-write the new hypervisor's boot-time
record with the boot-time of the previous hypervisor. This caused
time-dependent processes on the guests to fail 

This bug was apparently fixed in 3.1.1
(http://xenbits.xen.org/hg/xen-unstable.hg/rev/359707941ae8) but I am having
the issue now with Xen 4.0.1 on Debian Squeeze.

Did something change with the migrate/restore process so the previous fix no
longer applies?

Thanks in advance for any help
