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.

BUILD: qemu-kvm-rhev-0.12.1.2-2.481.el6 [469338] State: DELETED

I have tried 5 times each with win10-64 using usb.sh and following the steps in commnet #0.


Guest boots up successfully in both cases.

Having tried 5 time each with win10-64 and test_ues.sh for both

kernel version: 2.6.32-682.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.501.el6.x86_64

and

kernel version: 2.6.32-592.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.490.el6.x86_64,

the guest can boot up successfully in both cases.

The guest can not boot up might due to https://bugzilla.redhat.com/show_bug.cgi?id=1252134, as it didn't specify the cpu modle in the cli-5374.

Based on the test results above, and have confirmed it with the reporter, it should be the problem of cpu model.

And it should be a dup to https://bugzilla.redhat.com/show_bug.cgi?id=1252134 which is same as comment 4.


Hi Gerd,

Could you please help check comment 16?

Is there any info we may missed?
If no, could we close this bug ?

Thanks.

Looks very plausible, can be closed as duplicate I think.
