Thank you Harald for the bugreport that includes patch. I missed that
change when it were committed. The problem with slow migration bothered
me for quite some time, I've seen this thread on LP too, I argued with
Anthony Liguori against his dd buffer size suggestion. But it was
several months ago, while the fix is relatively recent. You just connected
all the ends together - thank you for this.
You are welcome!
I verified the change (it's commit 5e77aaa0d7d2f4ceaa4fcaf50f3a26d5150f34a6
upstream) and it appears to be correct for 0.12 branch too. I already
included it for the next debian release, if such a release will happen
for squeeze (due to feature freeze).
Thanks a lot!
Now, I'm questioning the severity you've choosen for this bug.
"Grave" is release-critical, when a package "breaks for most users".
I don't think many users uses migration, and no kvm package in any
stable debian series included working migration code. It might be
"important" if you really think it _is_ important, but grave? Why?
I also wonder how many people use KVM on Debian in bigger environments.
There, you certainly need save/restore and migrate. Maybe it is more often
used on Ubuntu, see the already mentioned
https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/524447/comments/3
So this bug is a blocker for bigger environments. In my opinion it would be
a pity if squeeze released without this 8 lines fix. Also, libvirt/KVM is
the preferred virtualization environment for Red Hat and Ubuntu, so I think
it is important for Debian as well. But feel free to adjust the severity
level to something more accurate, especially in the light of the current
situation with the freeze.
I wonder why this was not included in upstream 0.12.5 ...
Very few people cares about 0.12 as a whole. Speaking of 0.12.5 --
well, there were a few changes that probably should be there too,
but aren't. Some of them are in debian package.
I very much appreciate this work, of Debian generally and in this case of
you in particular!
Cheers
Harry
