Hi Laszlo Should i how to reproduce this issue as kvm QE? I think sanity checking suffices. 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? 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! resetting(my understanding is that reboot VM) many times VM from the inside, VM work normally.

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. Reviewed-by: Laszlo Ersek <lersek> Signed-off-by: Gleb Natapov <gleb> Signed-off-by: Anthony Liguori <aliguori.com> 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. http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-1-git-send-email-lersek%40redhat.com&forum_name=edk2-devel http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-2-git-send-email-lersek%40redhat.com&forum_name=edk2-devel http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-3-git-send-email-lersek%40redhat.com&forum_name=edk2-devel http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-4-git-send-email-lersek%40redhat.com&forum_name=edk2-devel http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-5-git-send-email-lersek%40redhat.com&forum_name=edk2-devel http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-6-git-send-email-lersek%40redhat.com&forum_name=edk2-devel http://sourceforge.net/mailarchive/forum.php?thread_name=1346770816-14130-7-git-send-email-lersek%40redhat.com&forum_name=edk2-devel
