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 FuXiangChun 2015-01-04 06:37:42 UTC 
Description of problem:
Boot win2012r2 guest with hv_relaxed&hv_vapic&hv_spinlocks=0x1fff&hv_time & -smp 80,cores=2,threads=1,sockets=40.  guest will reboot automatically during booting. 

If use "-smp 40" to boot guest.  guest works well. QE tested qemu-kvm-1.5.3-84.el7 & qemu-kvm-1.5.3-60.el7 & qemu-kvm-rhev-2.1.2-17.el7 as well. All hit this issue.  So this bug isn't regression bug. 

another.  If remove option "hv_relaxed&hv_vapic&hv_spinlocks=0x1fff&hv_time" or "cores=2,threads=1,sockets=40" from qemu command line.  guest works well.



Version-Release number of selected component (if applicable):
qemu-kvm-1.5.3-84.el7 
qemu-kvm-1.5.3-60.el7 
qemu-kvm-rhev-2.1.2-17.el7

host kernel:
3.10.0-220.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1./usr/libexec/qemu-kvm -name win2012R2-64 -M pc-i440fx-rhel7.1.0 -m 8G -smp 80,cores=2,threads=1,sockets=40,maxcpus=240\

-cpu SandyBridge,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_time \

-drive file=/home/win2012r2-64.qcow2-back,if=none,id=drive-blk0-0-0,format=qcow2,cache=none -device ide-drive,drive=drive-blk0-0-0,id=blk0-0-0,bootindex=1 \

Comment 1 Vadim Rozenfeld 2015-01-08 08:51:39 UTC 
Does it fail with BSOD, black screen, or just frozen?

Thanks,
Vadim.

Guest will automatically reboot when guest UI is loaded. As this bug is found on Intel big machine(160 cores), It has been returned. If need debug the other scenarios. QE will reserve it from beaker asap.  

QE tested this bug on AMD big machine(48 cores) with the same steps as comment0 ,  win2012 guest frozen during booting.  over-commit 32 vcpu number.
Comment 6 Vadim Rozenfeld 2017-08-08 03:54:08 UTC 
seems as the same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1451959

for more details please look at following information

Comment 7 Vadim Rozenfeld 2017-11-14 11:08:47 UTC 
can QE try reproducing this issue on the following build https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=14535540 ?

Thanks,

Test win2012r2 guest with the above build, the guest can boot normally.
