This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. > It is a Xen bug which is best fixed in Xen, but it can be
> easily worked around in the guest kernel. The bug will only hit in fairly
> limited circumstances (starting a 2+GB guest on a host with a CPU supporting GB
> pages).
Well, the circumstances are getting more and more common with more hosts supporting GB pages. But there are other problems with RHEL6 and RHEL<5.5 hypervisors on new hardware (mostly XSAVE), that I'm closing this as NOTABUG.
Clearing out old flags for reporting purposes. Chris Lalancette |
