RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

The "sandra tool" is the one available from http://www.sisoftware.net/ ?

If yes, it's not free (for non-personal use), do we have a company-wide license to use it?
Comment 5 Ademar Reis 2012-04-12 18:03:33 UTC 
Please try to reproduce it on a different CPU and/or different windows version so that we get an idea if this is a specific scenario or not.
Comment 6 Eduardo Habkost 2012-04-12 19:04:20 UTC 
Sandra is known to try to read non-architectural MSRs that we don't emulate, based solely on the CPU model IDs.

Probably this is a duplicate of (or very similar in nature to) Bug 691382. It's probably not going to be fixed, unless it's an easy to emulate MSR (that was not the case on bug 691382).

Do you have any messages on the host dmesg that can help us identify the MSR being read/written?

I can reproduce it with another host(AMD Phenom(tm) 9600B Quad-Core Processor).

this is dmesg log when guest BSOD.

AMD Phenon would never run a "-cpu SandyBridge" guest. Being a different CPU model, probably it's crashing on a different MSR (and it would be a different bug). Could you open a new bug with that information?
Comment 17 Eduardo Habkost 2012-07-20 13:17:13 UTC 
I will close it as duplicate of bug 691382, based on info of comment 10:
