It's not that good. At last look, it has *no* support for  configuring 
floppy or CD access at install time, no support for multiple virtual or 
physical disks, and no support for using using a Dom0 installed kernel 
in a DomU, as has been supported in Xen since its creation. It needs 
quite a lot of work, and the version in RHEL always lags significantly 
behind that of Fedora. Virt-manager is little better, and does not allow 
modification of a guest domain without shutting it down, which Xen 
itself *DOES* allow with the xm command.
I hope many of these issues have been addressed in FC9, but these sorts 
of issues are why I'm hoping for someone good with Perl to do a decent 
Webmin utility.
