Over the last couple of weeks, I have been thinking about costs relating to a building a new virtualization-based data center. “What?” I hear you say. “Everywhere is virtualized—there is no such thing as a greenfield site anymore!” I would have said that myself, but in the last month I have come across three, one of which is a company worth over a billion pounds.
As of Service Pack 1, SUSE Linux Enterprise Server 11 (SLES) supports KVM. The bald facts are as follows. SLES 11 SP1 is based on a 2.6.32 kernel and is now full supported on x86_64 processors which support hardware virtualization, for the following guest operating systems:
SUSE Linux Enterprise Server 11 SP1
SUSE Linux Enterprise Server 10 SP3
SUSE Linux Enterprise Server 9 SP4
We note there is no mention of other Linux guests or Windows guests. This post follows on from our previous post regarding the demise of Xen in Red Hat Enterprise Linux, and perhaps suggests the beginning of the end for Xen-based virtualization in Linux, but the story is far from clear.
On 2nd September (right in the middle of VMware’s VMWorld Conference in San Francisco) Red Hat, the dominant Linux vendor, announced (at its own Red Hat Summit in Chicago), that with its Red Hat Enterprise Linux 5.4 release it was “Setting the Virtualization Agenda”. In another post we will look at the validity of this claim. In this post we focus on the RHEL offering itself.
