kvm-kmod-2.6.32.2
Before continuing to pimp up the tree, let's quickly update kvm-kmod:
This release follows latest KVM updates in stable 2.6.32 and also includes the requested kvm kernel header installation. The latter is specifically targeting at QEMU as, in contrast to KVM's QEMU tree, upstream does not carry the latest kernel headers. QEMU should now be able to pick them up via 'pkg-config kvm-kmod --cflags'.
Find this new version at:
https://sourceforge.net/projects/kvm/files/kvm-kmod/2.6.32.2/kvm-kmod-2.6.32.2.tar.bz2/download
KVM changes since kvm-kmod-2.6.32:
- x86 emulator: limit instructions to 15 bytes
(to limit latencies on non-preempt hosts)
- Fix irq_source_id size verification
(fixes guest hang with exhausted IRQ sources
- Include pvclock MSRs in msrs_to_save
kvm-kmod changes since kvm-kmod-2.6.32:
- Install kernel headers and related pkg-config metadata
- Fix installation against non-current kernel
- Fix cleanup-on-error of kvm-kmod compat services
Merry Christmas,
Jan

Thanks for the new version!
I have some doubts that I would like to consult:
Can this version of kvm-kmod be used with any version of Linux kernel?
I have Linux 2.6.32 in a host, but I suppose that considering, by the date of publication of kvm-kmod, that the provided modules by this package are newer and fix several bugs of the provided modules by Linux 2.6.32.
Also I have another host with Linux 2.6.30 and KVM-88, both compiled by myself in that order. Then I didn't know that the userspace and the kernel modules could be updated in independent form with qemu-kvm and kvm-kmod, respectively; so I suppose that when installing KVM-88 in second instance, it will have overwritten the newest modules of Linux 2.6.30. Is it correct? In this case, can have some problem installing kvm-kmod 2.6.32.2 with Linux 2.6.30?
Today I had a problem with one of the VMs running under this environment of kvm-88 + Linux 2.6.30 (with modules of kvm-88, if what I said before is correct). This is a VM that runs a Java application server with high rate of I/O.
The server didn't respond reason according to it showed Nagios. When I acceded to host through the shell, it drew attention to me to see that uptime reflected about 14697 days! When trying to execute "top", the console was hung and I did not have another alternative that to do kill -9 of the process. This could have due to some bug of that version of KVM?
Perhaps it is an obvious question, but during the update process of the modules, the virtual machines must be down?

Merry Christmas,
Thanks. Merry Christmas also to all.

Not any version, but most.

kvm-kmod-2.6.32.2 contains the kvm modules from Linux 2.6.32.2. You're better off installing Linux 2.6.32.2 instead of kvm-kmod-2.6.32.2 on top of Linux 2.6.32 (since you get non-kvm fixes as well).

It should work without problems.

Looks like time drift. You should upgrade to more recent versions and report.

You cannot rmmod the kvm modules while virtual machines are running.

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