Back in 2010, however, the Xen Project suffered a blow when Red Hat dropped Xen in favor of KVMfor Red Hat Enterprise Linux (RHEL) 6, thereby leaving users of RHEL-based CentOS in the cold as well. “This has been quite painful for Xen users; CentOS has been and still is one of the most popular Linux distros for Xen users,” explained Lars Kurth, Xen community manager for Citrix, a key sponsor of the technology. “The consequence of Xen having been removed from CentOS 6 was that Xen and CentOS 5 users had no upgrade path.”
Well, Thursday brought good news for those on both sides of the problem thanks to the launch of Xen4CentOS, which has brought CentOS integration back to Xen at last.
