kvm-47 had a host memory corruption bug when setting the guest pte dirty
bit, so here's kvm-48 with a fix.
Note that guest time accounting, below, will only work with Linux 2.6.24+.
Changes from kvm-47:
- use precise cpu accounting on ppc and s390 (Christian Borntraeger)
- make guest time accounting actually work (Laurent Vivier)
- fix host memory corruption when setting the guest dirty bit
- allow swapping with older userspace (Anthony Liguori)
- allow custom memory setup using libkvm (Gerd Hoffmann)
Notes:
If you use the modules bundled with kvm-48, you can use any version
of Linux from 2.6.9 upwards.
If you use the modules bundled with Linux 2.6.20, you need to use
kvm-12.
If you use the modules bundled with Linux 2.6.21, you need to use
kvm-17.
Modules from Linux 2.6.22 and up will work with any kvm version from
kvm-22. Some features may only be available in newer releases.
For best performance, use Linux 2.6.23-rc2 or later as the host.

smp guests still not working with kvm-48:-( i can't image what others
can do to make it work. guests hang at random stage during boot. i
attached guests boot screenshot. setup:

i try guest-1 and huest-2 with 4 vcpu others with 1 vcpu.

the situation is even worse, the guests are hang during boot even with
single vcpu and even with kvm-46:-( i attached another screenshot. but
after i kill the guest and start it again it works. it seems the problem
occurs when i start more guest at the same time (eg. after reboot the
host). and it seems there is some kind of acpi error since all of the
guest hang screenshot contains some kind of acpi error.

What happens if you use "-noacpi" ?

in this case single cpu guests are working with kvm-48, but 4
vcpu/guests still hang:-(
