Comment 2 RHEL Program Management 2011-01-11 20:16:33 UTC

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

Comment 3 RHEL Program Management 2011-01-11 22:55:46 UTC

This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.

Tested this bug on latest build kvm-83-224.el5,it does not exist any more, f13 installed on f13 host can be run on rhel5.6 without any error.

Parameter ept=0 should be passed when loading kvm_intel.ko module.

Comment 8 Marcelo Tosatti 2011-02-23 19:58:13 UTC

Actually this should be fixed already by commit 62501ff6ab1a58aa1d on kvm-rhel5.git.
