Well, There is a patch, that may help.
It must be applied against clean KVM-61 (maybe it works with 62).
Must be applied vs. KVM kernel-space Makefile.
# cd kvm-61/kernel/
# patch -p1 kvm-susekernel.patch
# ./configure
# make
# make install
It helps here, on openSUSE Linux 10.3 host.
I hope

Here an example of the futher orthogonal work to do on top of #v8
during .26-rc to make the whole mmu notifier API sleep capable.
1) Every single ptep_clear_flush_young_notify and
ptep_clear_flush_notify must be converted like the below. The below is
the conversion of a single one. do_wp_page has
Difference between #v7 and #v8:
1) s/age_page/clear_flush_young/ (Nick's suggestion)
2) macro fix (Andrew)
3) move release before final unmap_vmas (for GRU, Jack/Christoph)
4) microoptimize mmu_notifier_unregister (Christoph)
5) use mmap_sem for registration serialization (Christoph)

Add basic KVM paravirt support. Avoid vm-exits on IO delays.
v1-v2:
- replace KVM_CAP_CLOCKSOURCE with KVM_CAP_PARA_FEATURES
- cover FEATURE_CLOCKSOURCE
v2-v3:
- switch to one ioctl per paravirt feature

Add support for the cr3 cache feature on Intel VMX CPU's. This avoids
vmexits on context switch if the cr3 value is cached in one of the
entries (currently 4 are present).
This is especially important for Xenner, where each guest syscall
involves a cr3

This patchset is based on Marcelo's v3. The biggest change is
dropping the generic hypercall multicall in favor of an mmu
specific hypercall. This brings the following benefits:
- no need to check whether the various hypercalls are compatible

Hi,
what's the status of kvm-lite? Has anybody worked on it since
the last september posting[1]?
Hi Fabio,
No, not really. I'll have to drag it up to date again and submit it for
merging so it doesn't keep bitrotting.
Thanks,
virtio-pci acquires its spin lock in an interrupt context so it's necessary
to use spin_lock_irqsave/restore variants. This patch fixes guest SMP when
using virtio devices in KVM.
