A bit of friendly mmu hacking.

Changes since kvm-26:
- use slab cache for mmu shadow pages
- make shadow pte updates atomic (for guest smp)
- general mmu cleanups

Notes:
If you use the modules from kvm-27, you can use any version of Linux
from 2.6.9 upwards.
If you use the modules from Linux 2.6.20, you need to use kvm-12. If you use the modules from Linux 2.6.21, you need to use kvm-17.

API/ABI stability is planned for Linux 2.6.22.

kvm >= 25: vmx.c no longer compiles on F7

Avi,

From kvm-25 onwards, vmx.c no longer compiles on Fedora 7:

{standard input}: Assembler messages:
{standard input}:4361: Error: no instruction mnemonic suffix given and no register operands; can't size instruction

After applying the attached patch, everything works as usual (kvm-25 to kvm-27)

Avi,

{standard input}: Assembler messages:
{standard input}:4361: Error: no instruction mnemonic suffix given and no register operands; can't size instruction

Applied, thanks.

Is this on i386? It's fairly suspicious if it happens on x86_64.

Also:
- your patch was corrupted (tabs were replaced by spaces). please don't
cut'n'paste from a terminal.
- supply sign-off-lines to kernel patches.

Yes, i386.

No, I didn't. Will check and improve.

Re: [ANNOUNCE] kvm-31 release

In reply to a message not in the archive

Hi,

Just compiled kvm-31 and found some strange things.

My system uses kernel-2.6.21-gentoo-r4 i386. But after kvm-31 is installed, I found /usr/local/kvm-31/bin/qemu-system-x86_64 instead of /usr/local/kvm-31/bin/qemu for 32 bit system.

Since there is no option for choosing what CPU arch to use, I guess the config script has some problem detecting correct cpu arch.

Simon
