This is interesting.
I prefer compiling from source especially for upgrading KVM on
production systems, because then I do not need to upgrade the kernel
(may introduce new stability issues on very new kernels) or the distro
(may introduce LOTS of new changes and stability issues on production
sytems). KVM is newer and evolves more rapidly than the kernel so it is
more beneficial to upgrade KVM than the rest of the kernel or distro
There's no need to compile kvm _modules_ if you're using recent-enough
kernel. I _fail_ to see why people are still using older and buggy
modules from kvm-88 with kernels >=2.6.30 where these modules are more
recent and with bugfixes. But that's entirely different point.
However for compiling from source I would need to know which versions of
KVM are "stable" and which are not.
qemu-kvm-n.nn.n are stable releases. First stable release (0.10)
already contained the fixes you mentioned. They're versioned exactly
like kernel - 0.10.0, 0.10.1, ..., 0.10.6 like 2.6.27 .. 2.6.26.36 or
what it is now. Current qemu-kvm is 0.11.0.
I see the 89 you tell about, is not released yet:
http://sourceforge.net/projects/kvm/files/
So did you mean that 89 is not "yet" for production use or will "never"
be for production use?
kvm-nn never was and never will be for production. They always has been
and always will be nothing more than development snapshots.
And the whole thing has been asked and answered numerous times here
and elsewhere.
