When we allow guest page faults to reach the guests directly, we lose
the fault tracking which allows us to detect demand paging. So we provide
an alternate mechnism by clearing the accessed bit when we set a pte, and
checking it later to see if the guest actually used it.

Booting RHEL 5 i386 in kvm with -no-kvm-irqchip -smp 4 will hang in
udev. I bisected this to a change in the _guest_ kernel:

Retested it on KVM-57.
It has been fixed already.
Actually, the fix is post kvm-57. What kvm-userspace.git commit did you
test?

While the change mentions that it fixes a time warp bug, it also says
it should be rare. So clearly kvm smp tsc handing is buggy.
Ingo/Thomas, (or anybody else), do you have any insight as to what kvm
can be doing wrong to trigger this behavior?
hm. Those time

According to Avi's comments, Updated the patches.
[1/3] Create ioapic.h and lapic.h to hold their declarations.
[2/3] Moving ioapic{.h,.c} back to common directory.
[3/3] Moving out kvm_vcpu_kick from irq.c
Applied all, thanks.

Subject: [PATCH] kvm: make ioapic structure in irqchip seen by ia64
IA64 also needs to see ioapic structure in irqchip.
Patch doesn't apply due to whitespace corruption.

Avi/Anthony:
Following commit added #UD trap in KVM and do emulation in KVM.
It is good to avoid the mis hypercall instruction issue, but I am not
sure if it will have any serious side effect. I am blind to AMD
instruction, I assume, for example, AMD 3D now

If you use the modules bundled with kvm-56, you can use any version

the external module (once patched) will only be able to build against 2.6.17

Since we don't emulate 3Dnow instructions, a #UD will be
injected instead.
OK, how many architecture specific instructiosn are emulated now?
Just vmcall/vmmcall (which is emulated once, then patched).
Or what is planed to be implemented? If no, then
