I have just installed Xen by following 
http://wiki.xen.org/wiki/Xen_Beginners_Guide
 
All in all pretty good, however it mentions using the xl toolset but when I first installed only the xm toolset would work. This was great for creating linux based domains but it gave me an error about hvm when I tried creating a Windows
 domain.
 
I then apt-get install xen-tools-common and edited /etc/default/xen to specify the xl toolset, rebooted and tried again.  This time when doing xl info the system returned:
 
WARING:  Can't find toolstack xl, fallback to default!
ERROR:  A different toolstack (xm) have been selected!
 
So I did apt-get remove xen-tools-common and rebooted and set /etc/default/xen to defaults.  Now when I try xl or xm info I get: “ERROR:  Toolstack not specifed and nothing detected, bailing out!”
 
And I’m stuck, I’ve googled the error but can’t find anything and am not sure what to check now.
 
Thank you.
