[Pkg-xen-devel] Bug#512491: xen-utils-3.2-1: xc_save segfaults during migration

[Rik Theys]

Package: xen-utils-3.2-1
Version: 3.2.1-2
Severity: normal

*** Please type your report below this line ***

When live migrating a PV guest from one Lenny dom0 to another, the 
migration fails with the
following error:

libvir: Xen Daemon error : POST operation failed: xend_post: error from 
xen daemon: (xend.err '/usr/lib/xen-3.2-1/bin/xc_save 28 39 0 0 1 failed')

The kernel messages show a segmentation fault:

[2124821.069778] xc_save[9907]: segfault at 7f2bb1d72698 ip 7f2bb11f8237 
sp 7fffb9d7b950 error 4 in libc-2.7.so[7f2bb11b4000+14a000]

The domain stays paused for 30s on the new target host and then recovers 
and runs OK. The guest is not
loaded so I don't know what happens if the guest is loaded.

The guest is a RHEL 5.3 with kernel 2.6.18-128.el5xen.


Regards,

Rik
