Summary: Xen 4.0.1 live migration restore over-writes new
hypervisor's boot-time record (a.k.a. bug 1282 is back)
Product: Xen
Version: unstable
Platform: x86-64
OS/Version: Linux-2.6
Status: NEW
Severity: major
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@lists.xensource.com
ReportedBy: bugs@linuxrehab.com
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
