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.

backport the following commit from upstream:

commit 4d09d37c6aa9a02b44b1fdb6268820fab92499bd
Author: Gleb Natapov <gleb>
Date:   Tue Aug 7 15:52:03 2012 +0300

    reset PMBA and PMREGMISC PIIX4 registers.
    
    The bug causes Windows + OVMF hang after reboot since OVMF
    checks PMREGMISC to see if IO space is enabled and skip
    configuration if it is.

I've just posted a series for OvmfPkg that changes the platform pre-EFI initialization such that it depends on (PMREGMISC & PMIOSE) == 0 rather than on !Xen. I'll need the designated commit in RHEL-6 so that I can use official Brew builds to test OVMF + Windows.

Hi Laszlo
   Should i how to reproduce this issue as kvm QE?

Comment 7 Laszlo Ersek 2012-10-10 08:43:50 UTC
I think sanity checking suffices.

Comment 9 FuXiangChun 2013-01-04 03:12:06 UTC
verify this issue with qemu-kvm-0.12.1.2-2.348.el6.x86_64 and kernel 2.6.32-348.el6.x86_64

Do sanity testing with two scenarios

1. Install guest with Windows8-ConsumerPreview-64bit-English.iso
CD-ROM: IDE
disk: IDE
NIC model: e1000
RAM: 4G
VCPUs: 4
disk size: 30G
connection: vnc

2.Install guest with Windows8-ConsumerPreview-64bit-English.iso
CD-ROM: IDE
disk: virtio-blk-pci
NIC model: virtio-net-pci
RAM: 2G
VCPUs: 4
disk size: 30G
connection: spice

result:
win8 can be installed successfully and works well. 

Laszlo,
according to testing result. can verify this bug?

Comment 10 Laszlo Ersek 2013-01-04 07:57:59 UTC
The important thing to test is resetting the VM. (That is, don't create a new VM, instead, reset the VM from the inside.)

IIRC windows8 installation involves several resets (at least three). I think you can set this to VERIFIED. Thanks!

Comment 11 FuXiangChun 2013-01-05 06:32:32 UTC
resetting(my understanding is that reboot VM) many times VM from the inside, VM work normally.
