Avi,
This is the updated patch, which avoids inactive hrtimers from
unintended migrations.
save/restore timer logic is not included because it does not call
hrtimer_cancel (hrtimer_active is different). It has relatively small impact,
for it only affects save/restore at maybe guest BIOS
The issue is fixed after applied the patch.
Thanks a lot!

Hello,
I'm getting "unhandled vm exit:0xb8002" running a Debian Etch guest
under kvm36 on AMD64.
The host is a 4-core dual-dual AMD, and I was able to create the Debian
Etch (4.0) guest image just fine, using a standard install, from the
standard Debian DVD disc1: debian-40r0-i386-DVD-1.iso
D
As discussed previously, this patch directly passes SMP CPU count to the
guest BIOS from CMOS by qemu, instead of sending SIPI and wait. CMOS
offset 0x7f is used.
This is the last functional piece for in-kernel APIC merge in kvm-37.

Well, it seems hrtimer-compat patch breaks the build.
HRTIMER_MOD_ABS is declared in enum, so we can’t say:
#ifndef HRTIMER_MOD_ABS
#define HRTIMER_MOD_ABS HRTIMER_ABS
#endif
maybe something like
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2.6.?)
should be OK
I meet the following error when I build latest kvm master against kernel
2.6.22 as external modules.
And it's ok if I build it against kvm kernel either build-in or as
external modules.

Hi,
while debugging a program with GDB I got a GPF which seems related to
KVM. Note that I was *not* using the debugger inside the guest nor on

A guest context switch to an uncached cr3 can require allocation of
shadow pages, but we only recycle shadow pages in kvm_mmu_page_fault().
Move shadow page recycling to mmu_topup_memory_caches(), which is called
from both the page fault handler and from guest cr3 reload.
