[ANNOUNCE] kvm-85 release

[ANNOUNCE] kvm-85 release

[Avi Kivity]

Again a long delayed release; I'll try to reduce the lag between releases.

kvm-85 comes in two flavors: the traditional kernel+qemu package 
(kvm-85.tar.gz), as well as separate qemu (qemu-kvm-devel-85.tar.gz) and 
kernel module (kvm-kmod-devel-85.tar.gz).  The separate packages can be 
used by those who wish to use the kvm kernel modules from their 
distribution, while the combined package offers the convenience of an 
all-in-one source package.  The future stable branch will be based on 
the separate packages.

Notes:
     If you use the modules bundled with kvm-85, you can use any version
of Linux from 2.6.16 upwards.  You may also use kvm-85 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.

I packaged this in Fedora 12 as qemu-0.10.50 and noticed a couple of
small problems with the qemu-kvm-devel tarball:

  - No kernel/include/asm symlink, so it was building with the system 
    headers and not finding e.g. KVM_FEATURE_CLOCKSOURCE

  - An empty kvm-85 dir

And for anyone else doing similar packaging, I've also:

  - Disabled pwritev() support until glibc stops writing random junk. 
    See https://bugzilla.redhat.com/497429

  - Added Pauline's boot=on -help string patch

  - Fixed the arm target build with the patch I just sent

Cheers,
Mark.

Wouldn't it be useful to have it disabled upstream then?

No glibc has been released with the broken one yet, I gusee Mark must
have been running some sort of snapshot.

This is already fixed in the new repository.

I need to rewrite my release script anyway.

I hope to release kvm-86 soon.

Yeah, it's a pre-release snapshot of 2.10 which will be included in
Fedora 11. 

Looks like it's fixed upstream already and we'll have a new snapshot
very soon.

Cheers,
Mark.
