Sure, I've tested on Fedora Core 3 and on Gentoo both running various 
copies of xen-unstable (ranging from a few weeks ago to a day ago).  
There are a number of others (Mike, Woody, Dan) that have tested on 
other platforms.

By tested, I mean was able to create and destroy domains with various 
arrangements of block devices and network devices (0, 1, 2, etc, etc.).  
I've tested using a custom busybox based ramdisk and ttylinux as DomU.  
Other DomU configuration should also work (although haven't been tested).

Yes, the goal was to minimize the amount of features to the least amount 
required before release.  We're very interested in hearing feedback on 
what the tools should look like.

USB and PCI support isn't that hard.  Doing in a way that people feel is 
intuitive is another matter.  Feed-back on what sort of interfaces these 
tools should have is extremely useful.

That depends on demand.  The tools could be modified to open the 
controls channels directly instead of going through xcs, but I'd rather 
encourage an xcs based world where Xend and vm-tools can live together.  
Of course, if someone was willing to backport the old Xend to xcs... :-)

Thanks,
