Talking about regressions...

[Michael Riepe <michael-0QoEqw4nQxo@public.gmane.org>]

When I did a couple of tests the other day, I noticed that one or more
bugs must have been introduced at least into the vmx part in kvm-10:

- netbsd 3.1 used to work with kvm-9. In kvm-10, the system hangs during
boot. One of the last things I can see is that a shell process dies with
a SIGSEGV. Then the load rises to 100% (sys) on the host and stays there
until I kill qemu (yes I've waited several minutes).

- opensolaris displays a "Time of Day clock error" during boot, claiming
the clock has jumped by 0x5 (no unit given, I suppose that means
seconds). Everything else seems to work.

- qemu-puppy-2.13-1 sometimes works and sometimes hangs somewhere inside
the initial ramdisk. The exact place seems to differ, but usually it
happens while the kernel modules are loaded. Again, host load rises to
100%. An older version (2.01-3) still works fine. kvm-9 works, too.

(Core Duo T2400, 32-bit SMP host, 32-bit guest, Linux 2.6.19 + kvm trunk
revision 4290)

Any idea what to look for? The SIGSEGV on netbsd makes me suspect that
there's a problem with the page tables, but I couldn't narrow down the
cause yet.
