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.

Description of problem:

In RHEL7.0 host, boot win2012r2 guest. Guest would go to black screen with the error code: 0x000000c4. The screen shot is as file screenshot-1.

Version-Release number of selected component (if applicable):
kernel-3.10.0-69.el7.x86_64
qemu-kvm-rhev-1.5.3-36.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. boot win2012r2 guest
qemu \
    -S  \
    -name 'virt-tests-vm1'  \
    -sandbox off  \
    -M pc  \
    -nodefaults  \
    -vga std  \
    -monitor stdio \
    -chardev socket,id=serial_id_serial0,path=/tmp/serial-serial0-20140120-181307-tQEO7hpz,server,nowait \
    -device isa-serial,chardev=serial_id_serial0  \

    -device isa-debugcon,chardev=seabioslog_id_20140120-181307-tQEO7hpz,iobase=0x402 \
    -device ich9-usb-uhci1,id=usb1,bus=pci.0,addr=03 \
    -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=pci.0,addr=04 \
    -drive id=drive_image1,if=none,cache=unsafe,snapshot=off,aio=native,file=data/images/win2012r2-64-virtio.qcow2 \
    -device scsi-hd,id=image1,drive=drive_image1 \
    -device virtio-net-pci,mac=9a:08:09:0a:0b:0c,id=idcawy4P,netdev=idI43hgO,bus=pci.0,addr=05  \
    -netdev tap,id=idI43hgO,vhost=on,script=/etc/qemu-ifup  \
    -m 8192  \
    -smp 2,maxcpus=2,cores=1,threads=1,sockets=2  \
    -cpu 'Conroe',+kvm_pv_unhalt,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic \
    -drive id=drive_cd1,if=none,snapshot=off,aio=native,media=cdrom,file=data/isos/windows/winutils.iso \
    -device scsi-cd,id=cd1,drive=drive_cd1 \
    -device usb-tablet,id=usb-tablet1,bus=usb1.0,port=1  \
    -vnc :1  \
    -rtc base=localtime,clock=host,driftfix=slew  \
    -boot order=cdn,once=c,menu=off \
    -enable-kvm

2. watch the vnc booting screen
3.

Actual results:
guest goes into black screen and repeated the booting process
The error code is 0x000000c4 as the screenshot-1

Comment 2 Ronen Hod 2014-01-20 15:08:06 UTC 
xhan,

Please try the hotfix from http://support.microsoft.com/kb/2816159
(actually, I do not know if it can be applied if you cannot boot).
Does it mean that 2012R2 never managed to boot on RHEL7? Maybe we need to somehow bisect, since it worked on RHEL6.
Comment 3 Yvugenfi@redhat.com 2014-01-20 15:25:42 UTC 
Very strange bug check code.

1. First 0xC4 is reserved for driver verifier. Did you turned it on? Was this image ever used for HCK certification?


2. Parameter 1 equal to 0x91 of 0xC4 bug check means - "The driver switched stacks using a method that is not supported by the operating system. The only supported way to extend a kernel mode stack is by using KeExpandKernelStackAndCallout."  - http://msdn.microsoft.com/en-us/library/windows/hardware/ff560187(v=vs.85).aspx

Do you have anti-viruses installed on this image? 
Is this image clean or did you installed some SW on it before testing?

3. Please try to boot with safe mode and fetch the memory crash dump from the guest.

Best regard,
Yan.

Maybe it's related to the cpu flags for this bug is similar to 
Bug 1044979 - win8.1.x86_64 / win2012r2 guest will circling reboot when boot with -cpu 'Conroe' 

https://bugzilla.redhat.com/show_bug.cgi?id=1044979

Thanks,
Cong
Comment 7 xhan 2014-01-22 06:57:14 UTC 
Change to -cpu 'host', then boot win2012r2 successfully.
