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.

Doc Type: Bug Fix
Doc Text:
Cause: WHQL cannot pass DF jobs on Windows 7 guest, because guest failed to resume when started with hv_time flag enabled. Consequence: Enabling hv_time flag prevent Windows 7 guest from successful resuming, when running WHQL DF jobs. Fix: Update kernel, qemu and virtio-win drivers with the most recent ones. Update Result: DF jobs can be passed on Windows 7 guest with hv_time flag enabled.

Description Min Deng 2014-03-19 07:17:08 UTC 
Description of problem:
Started with DF* jobs failed because WIN7-32 and Win7-64 guest hang if guests rebooting during test stage
Version-Release number of selected component (if applicable):
build 75
kernel-3.10.0-111.el7.x86_64
qemu-kvm-rhev-1.5.3-53.el7.x86_64
How reproducible:
3 times
Steps to Reproduce:
1.boot up guest with 
  /usr/libexec/qemu-kvm -M pc -m 2G -smp 2 -cpu Nehalem,+x2apic,hv_spinlocks=0x1fff,hv_relaxed,hv_vapic,hv_time -usb -device usb-tablet -drive file=win7-32.raw,format=raw,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none -device ide-drive,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,id=hostnet0,script=/etc/qemu-ifup1 -device e1000,netdev=hostnet0,mac=00:42:45:38:44:12,id=net0 -uuid 3122984b-7e74-4afa-8dc0-66cecf65aea4 -rtc-td-hack -no-kvm-pit-reinjection -chardev socket,id=a,path=/tmp/monitor-win7-32-serial,server,nowait -mon chardev=a,mode=readline -name win732-serial -device virtio-serial-pci,id=virtio-serial0,max_ports=16,vectors=4,bus=pci.0 -chardev pty,id=channel0 -device virtserialport,chardev=channel0,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0 -vnc :1 -vga cirrus -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=0 -monitor stdio
2.submit the job 
  for example,
   win7-64,DF-PNP Rebalance Request New Resources Device Test...
   Win7-32,DF-PNP Stop ...
3.

Actual results:
The guest could not boot up correctly and it hang up so the following jobs could not continue.
-cpu Nehalem,+x2apic,hv_spinlocks=0x1fff,hv_relaxed,hv_vapic,hv_time - *reproduce
-cpu Nehalem,+x2apic,hv_spinlocks=0x1fff,hv_relaxed,hv_vapic, - *not reproduce


Expected results:
The job could pass with hv_time flag.

Comment 2 Ronen Hod 2014-03-19 08:40:44 UTC 
Since we have the option not to use hv_time, and the default is that it is off, this is not a very urgent 7.0.0 blocker. Deferring to 7.1 (and 7.0.z for now).
Comment 4 Min Deng 2014-11-14 05:26:56 UTC 
  QE re-run the jobs on win7-32 and win7-64 guest for virtio serial 
build info,
kernel-3.10.0-200.el7.x86_64
qemu-kvm-rhev-2.1.2-7.el7.x86_64
virtio-win-prewhql-0.1-93
  All the jobs named by DF* have passed on win7-32/64 guest with flag '-cpu Nehalem,+x2apic,hv_spinlocks=0x1fff,hv_relaxed,hv_vapic,hv_time' so the original issue has been fixed,thanks.
Comment 5 Ronen Hod 2014-11-19 16:12:53 UTC 
Since it is already solved, Moving back to 7.1, ON_QA
Comment 6 juzhang 2014-11-24 01:45:44 UTC
