Excuse me because I am about to redirect this thread to a different topic that has nothing to do with XCP.

Apart from these issues everything else should work as before. Do you think you'll be able to adapt OpenNebula to use the new toolstack? If you don't use the features above it shouldn't take much more than ln -s xm xl. It is worth mentioning that xend and xm are still available in the 4.1 release, just not recommended anymore. P.S. you may understand now what the confusion was about: XCP has a different toolstack called xapi, it doesn't use xend at all. However XCP has a copy of xl for debugging purposes, but it shouldn't be used for anything but debugging on a XCP system. So if you want to integrate XCP into OpenNebula you should use the appropriate RPC calls supported by xapi. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
