i Avi,
we currently try to integrate this patch for an update into a 2.6.32
based
system (amongst other kvm updates). But as soon as this patch gets
added kvm
will die on startup in kvm_leave_lazy_mmu. This has been documented here:
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/531823
I have placed the backports of your patches, which are currently in
linux-next
and marked for stable here:
git://kernel.ubuntu.com/smb/linux-2.6.32.y kvm
I have tested the failure with a version that got only the following
patches in:
KVM: x86 emulator: Add Virtual-8086 mode of emulation
KVM: x86 emulator: fix memory access during x86 emulation
KVM: x86 emulator: Check IOPL level during io instruction emulation
KVM: x86 emulator: Fix popf emulation
KVM: x86 emulator: Check CPL level during privilege instruction emulation
and also with a version that takes all stable patches up to the bad one:
KVM: VMX: Trap and invalid MWAIT/MONITOR instruction
KVM: x86 emulator: Add group8 instruction decoding
KVM: x86 emulator: Add group9 instruction decoding
KVM: x86 emulator: Add Virtual-8086 mode of emulation
KVM: x86 emulator: fix memory access during x86 emulation
But as soon as the fix for memory access gets added, the bug will
occur. Would
you have an idea what might be causing this?
Does the same guest, using the same qemu-kvm, work on kvm.git or upstream?
The test was done with a kvm user-space package based on 0.12.3 (which seems to
be the current upstream version). I try to do a test on the git version.
I meant keep the same userspace without change, and try it on a Linus
kernel or kvm.git master
(http://git.kernel.org/?p=virt/kvm/kvm.git;a=summary).
