Red Hat Bugzilla – Bug 210318
Add test for SVM disabled via BIOS
Last modified: 2007-11-30 17:07:35 EST
Description of problem:
Newer BIOS implementations will be able to disable the SVM feature,
although an additional test of an MSR (VMCR 0xC0010114 bit 4) is
necessary (set equals disabled). Bit 4 of MSR 0xc0010114 returns 0 (SVM
enabled) on machines with older BIOS' without the SVM disable feature
Version-Release number of selected component (if applicable):
Applies cleanly to 11730 upstream. We have requested that the patch
be applied to xen-unstable.hg and xen-3.0.3-testing
Created attachment 138243 [details]
Check whether SVM is disabled in the BIOS
please ensure that changesets 11750 and 11751 from the 3.0.3 xen repository
are utilized for this fix.
OK, verified that this patch is in Xen changeset 11774, which is in RHEL5 B2.
