Hello,

current xen-unstable.hg-4.1.22019 fails to run 'xm start <name>', while
xen-unstable.hg-4.1.21976 was still ok.
Its not obvious from browsing the diff between the two trees whats the cause.
Any other info required besides the one pasted below?

# xm start $name
Error:

                                 is created
