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).

Actual results:
Failed to boot guest and show the Error Code: 0x0000005D. see attachment

Expected results:
It should boot guest successful

Additional info:
Failed to boot Win8/win2012 guest(boot win7 guest successfully), but can boot successfully in local machine.

Comment 5 Ronen Hod 2013-09-28 22:39:05 UTC 
Qunfang,
I searched the Internet and found out that older CPUs that do not support the NX/XD bit, cannot run Win8 (also on bare metal).
I suggest that you try a different CPU type, and if it works, close the bug.
Thanks, Ronen.
Comment 6 Qunfang Zhang 2013-09-29 05:59:17 UTC 
Hi, Ademar and Ronen

Thanks for the reply. From the comment 0, we could see there's no 'nx' flag in the cpu info, but we re-check the system again just now, the 'nx' flag exists! So we will re-test again to see whether the problem is still reproducible. And btw, we tested on some other system, could not reproduce the issue.

Thanks,
Qunfang

Steps as comment 0

There is nx flag this time, maybe last time(comment 0) disable nx flag. this time can boot win8 guest successful,so I will close this bug, If I am wrong, please let me know it. 

Best Regards!
Comment 9 Ronen Hod 2013-10-16 11:46:19 UTC 
Gleb,
Junyi asks about emulating the NX flag on CPUs that do not support it. Maybe you can answer.
