Ben, yes, sorry I missed the fact that there was already another bug
that needs verification in lucid-proposed. Bug #592010 needs to be
verified, or reverted, before this one can proceed to lucid-updates.
Verification is tricky, since one needs to do a hardy -> lucid upgrade
to verify it.

Bug description:
==================================
SRU Justification:
1. impact: 'qemu save' is slow
2. how addressed: a patch upstream fixes the case when a file does not
announce when it is ready.
3. patch: see the patch in linked bzr trees
4. TEST CASE: see comment #4 for a specific recipe
5. regression potential: this patch only touches the vm save path.
==================================
As reported here: http://www.redhat.com/archives/libvir-
list/2009-December/msg00203.html
"virsh save" is very slow - it writes the image at around 1MB/sec on
my test system.
(I think I saw a bug report for this issue on Fedora's bugzilla, but I
can't find it now...)
Confirmed under Karmic.
