RE: [Xen-users] my first XEN Installation I need some advice

[Nathan Eisenberg <nathan@xxxxxxxxxxxxxxxx>]

I've had huge issues with Hyper-V's performance in production.  The blockIO 
layer is significantly worse than vanilla HVM in Xen.

If you can live with the "hacks" required (see other responses) then
you should be fine.
If you want easy installation, use RHEL/Centos, and optionally Xen
packages from http://www.gitco.de/repo/
IMHO this is the easiest way to get the latest version of Xen running.

Other users have reported that Debian dom0 also runs quite well.

If all your domUs are Windows, it'd probably be better if you use
Windows 2008's Hyper-V instead.

Yes

No.
To get maximum performance, you should use block device (partition,
LVM) as domU backend instead of using file-backed storage (the default
option). And don't forget to install GPLPV.
