Thread-topic: [Xen-devel] RE: "xm create" take more time to return.
Hi keir
Our testing is base on xm now . And we know xl will be official supported by 
xen 4.1, so should we move to xl now or after xen 4.1 release?

BTW: we had investigated xl several months ago, and there were some problems 
with it(I have send a mail to discuss it before), but I am not sure whether 
those bugs are fixed or not.

best regards
yang
