This was just posted on the Windows virtualisation blog:
“With the release of WS08 R2 version of the ICs, we’ll also add support for SLES 11 and RHEL 5.2 and 5.3”.
“Official support” is different to integration components. As I reported earlier today, MS released the IC’s for Linux under the GPLv2 license so that enlightened drivers would be built into more Linux distributions for enhanced performance. Official support means that MS has tested things completely and PSS will take calls. The addition of RedHat and SLES 11 is superb news – something we knew was coming for ages but we didn’t know when. We can already manage RH and SLES using Operations Manager 2007 R2.
