[KVM] ANNOUNCE: new kvm userspace release

[Avi Kivity]

Changes:
  - much easier to get running, see updated HOWTO
  - now just one download, get yours while supplies last
  - single qemu binary for kvm and non-kvm runs (Anthony Liguori)
  - accompanying external kernel module package has all bugfixes folded 
in (plus a bit of cosmetics)

The patch you put up on Nov 2 was a really easy to work with. Nicely
done! I installed it here and it ran successfully. It booted a windows
2003 server image successfully. I attached a screenshot.

Time runs at about half speed inside a linux guest.

Between qemu+kvm and just qemu (on the same hardware) there doesn't
seem to be an obvious difference in speed. I didn't look around much
more than just booting a few images so far; so that's all I'm basing
that unscientific estimate on.

For me, this Nov 11 tarball is a lot harder to work with. For the
kernel module, I can't tell by inspection what patches have been
applied from the mailing list. For qemu, the whole qemu upstream is
extracted in there so if I want to get a clean patch now I would have
to guess which version to start will and make my own diff.

Enjoy,
Jeff

Thanks for the success report.  It makes a welcome change from the bug 
reports :)

Hmm.  What are the guest's and host's CONFIG_HZ?

It depends on the hardware.  We find that the Core 2s and the AMDs do 
very well.

The planned MMU optimization will improve the speed considerably.

The intent was to reduce the amount of downloading and compilation 
needed to make it work.  I guess one size does not fit all.

For the record, the modified qemu is based on Fedora's qemu-0.8.2 and 
the external kernel module is equvalent to all patches posted up to date 
plus a couple of cosmetic fixes.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Both 250. 2.6.17 in this case (debian sarge). The time is normal
without kvm.

Please open a bug in the sourceforge bug tracker, as I'm unlikely to get 
to this in the next few days.
