[ANNOUNCE] kvm-84 release

[ANNOUNCE] kvm-84 release

[Avi Kivity]

A long list of changes due to an unusually late release.  As is becoming 
usual, many of the changes come from upstream qemu; the kvm specific 
changes are mostly bugfixes, but also include infrastructure intended 
for message-signalled interrupts (MSI).

kvm-84 is slower when rendering fonts on Windows than kvm-83; we are 
still investigating why.

Notes:
     If you use the modules bundled with kvm-84, you can use any version
of Linux from 2.6.16 upwards.  You may also use kvm-84 userspace with
the kvm modules provided by Linux 2.6.25 or above.  Some features may
only be available in newer releases.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Does this fix the qcow2 corruption issue reported on the list last week
on this list? (qcow2 corruption observed, fixed by reverting old change)
