Re: XenServer 7

[John Burwell <jo...@shapeblue.com>]

All,

Has anyone had a chance to try XenServer 7 since it’s release?  If so, does it work?  If not, how broken is it?  My guess would be in agreement with the general consensus that a change from CentOS 5 to 7 would not only be breaking, but significant.

Thanks,
-John
