[ANNOUNCE] kvm-18 release

[ANNOUNCE] kvm-18 release

[Avi Kivity]

This is mostly to fix the 32-bit Linux guest breakage in kvm-17.

Changes from kvm-17:

- merged new userspace API
- revert the optimization which killed some 32-bit Linux guests
- reboot support on Intel hosts (AMD are already supported)
- better timekeeping under load (Uri Lublin)
- other minor fixes and cleanups

Note that if you use the modules from Linux 2.6.20, you need to use
kvm-12.  You can use kvm-18 with Linux 2.6.20, provided you use the
external module included in kvm-18.  API/ABI stability is planned for
Linux 2.6.22.

Well, almost. Knoppix 5.0 and 5.2 work now, but 5.1.1 still hangs with a
black framebuffer (no penguin logo) and a load of 100%.

Everything else still works as fine as with kvm-17.

Great work!

Do you have msr complaints in dmesg? Can you try booting the guest with 
nmi_watchdog=0?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Yep. After a while, I get:

	kvm: emulating exchange as write
	kvm: unhandled wrmsr: 0xc1
	inject_general_protection: rip 0xc01154d0

With nmi_watchdog=0 on the kernel command line, the system boots and all
the messages are gone. :-)
