Notes:
If you use the modules bundled with kvm-70, you can use any version
of Linux from 2.6.16 upwards. You may also use kvm-70 userspace with the kvm modules provided by Linux 2.6.22 or above. Some features may only be available in newer releases.

Thanks for the new release Avi. I'm trying to get kvm-71 to compile on RHEL 5.2 (x86_64), but I'm running in a typedef 'bool' issue. Here is my output... I've run thru the 1st make, so this make only shows the problem.

I needed to trivially modify configure to be able to build ALSA audio

(via ./configure --audio-drv-list=alsa)

Fix attached.

this will disable the default driver of "oss" and only enable alsa, where most likely what you want is :

./configure --audio-drv-list="alsa oss"

the fix proposed wouldn't allow for a list of drivers passed and is incorrectly assigning opt to itself and should do instead :

opt="$optorig"

sadly, the only solution I could come with, violates the current layering by handling the two list options in kvm instead, at least as a passthrough that would preserve the parameter count and formatting.
