SLES 10.2 under Hyper-V


SMP is not supported in Linux VM’s at this time with the IC’s loaded. If the IC’s aren’t loaded, then SMP works, albeit with lower I/O performance. Linux VM’s without IC’s are not supported by Microsoft.

You will find that attempting to boot the VM in SMP mode with IC’s loaded you will get the following;

VMBUS: SynIC version: 1

Moving forward, MS have identified the fix and will fix it in a future release. To fix the issue, you need to compile your own 2.6.32 kernel and apply a patch to make the IC’s SMP safe. At this time, the SMP fix is not publically available.
