There is the XenAPI (or alike) that allows local and remote management. I didn't use it (only just got it running a bit), but it seems to be what you need. <http://wiki.xensource.com/xenwiki/XenApi> However, the API is not stable, according to the website. - Joris _______________________________________________________ Linux-HA-Dev: [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/
