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.
Hi all
QE side can verify this Bug now.
re-test steps:
1) Boot the windows10-1803 guest.
/usr/libexec/qemu-kvm -enable-kvm -M pc \
-cpu SandyBridge,+kvm_pv_unhalt,hv_stimer,hv_synic,hv_time,hv_relaxed\
-nodefaults -smp 4 -m 4G -name win10-1803 \
-drive file=Windows10-1803.qcow2,if=none,id=guest-img,format=qcow2,werror=stop,rerror=stop -device virtio-blk-pci,drive=guest-img,id=os-disk,bootindex=1 \
-vga qxl -monitor stdio -boot menu=on -vnc :1 \
-netdev tap,id=hostnet0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:84:ed:01:00:06 \
-usbdevice tablet
2) use top command to monitor host cpu usage and save to a file.
e.g #top -p 6358 -n 1800 -d 2 -b >fixed-top-pc-result (about 30 mins)
3) calculate average value with this file.
# cat fixed-top-pc-result |grep qemu-kvm|awk -F ' ' '{print $9;}'|awk '{sum+=$1} END {print "Average = ", sum/NR}'
Average = 2.44881
Environment:
kernel:4.18.0-33.el8.x86_64
qemu-kvm-3.0.0-1.el8+2055+38c90e40.x86_64
Thanks
As QE used wrong kernel version to verify this bug. So, please ignore comment6 test result. and move this bug to ON_QA. Sorry to bring you some confusion.
Hi :
According the best new test result when using the fixed kernel version. The result looks good.
Released-version number:
[1] 3.10.0-957.3.1.el7.x86_64
[2] qemu-kvm-rhev-2.12.0-19.el7.x86_64
Repeat the steps exactly same with the comment#6
Result:
Average = 4.36678
Now, this BZ can be made Verified.
Thanks
