[Xen-ia64-devel] Xen/IPF Unstable CS#16848 Status Report -- HVM Guest Save Failed

["Mu, Qin" <qin.mu@xxxxxxxxx>]

Xen/IA64 Unstable Cset #16848 Status Report

Failed to save HVM guest domain. After invoking "xm save <dom_id>
<dom_id_checkpoint>", 
        1. A check point file of name <dom_id_checkpoint > was created,
but no response can be received any more.
        2. A process /usr/lib/xen/bin/qemu-dm was running corresponding
to the guest HVM to be saved.
        3. An item named "migrating-dom_id" was listed after commanding
"xm list".
        5. Create other HVM guests can still work.

The similar problem also occurred on Xen/IA32: #16764 & Xen0: #391. A
bug was therefore issued on bugzilla:
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1145
