Enable Balloon's logging
Hit same issue with win2016 guest after hotplug balloon device under q35, not always reproducible. Please give a try to new build b179 https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=1083820 Balloon still does't work with 179 version according to steps in comment 27. so reassign. Try 1000 times,didn't reproduce it with comment0. So close this bug and open a new one with step 27. new bug: https://bugzilla.redhat.com/show_bug.cgi?id=1828654 (In reply to xiagao from comment #37) > Try 1000 times,didn't reproduce it with comment0. > So close this bug and open a new one with step 27. s/step/comment > new bug: https://bugzilla.redhat.com/show_bug.cgi?id=1828654 Recently we run test for virtio-win-1.9.12-2.el7.iso(balloon driver version: 177) Hit this issue again in win8-32/64,win8.1-32/64,win2012-64/r2 again. Almost 1/10 hit this issue. host version: qemu-kvm-rhev-2.12.0-48.el7.x86_64 kernel-3.10.0-1154.el7.x86_64 So I will reopen this bug to track this issue. Hi developer, Do we want to fix this in RHEL8.2.1, but as RHEL8.2.1 is released on the 13th of July ,I propose to defer to the later version, what do you think? Thanks, xiagao Sure Hit this issue again recently: 161-Host_RHEL.m7.u9.qcow2.virtio_blk.up.virtio_net.Guest.Win8.x86_64.io-github-autotest-qemu.balloon_check.balloon_evict.balloon-reboot/ 158-Host_RHEL.m7.u9.qcow2.virtio_scsi.up.virtio_net.Guest.Win8.x86_64.1.io-github-autotest-qemu.balloon_check.balloon_evict.balloon-reboot/ 210-Host_RHEL.m7.u9.qcow2.virtio_blk.up.virtio_net.Guest.Win10.x86_64.io-github-autotest-qemu.balloon_check.balloon_enlarge.balloon-reboot/ pkg version: virtio-win-1.9.14-1.el7.iso kernel-3.10.0-1160.6.1.el7.x86_64 qemu-kvm-rhev-2.12.0-48.el7_9.1.x86_64 seabios-bin-1.11.0-2.el7.noarch After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. Please test it with the latest pre-whql driver. Tried 50 times with the latest pre-whql driver virtio-win-prewhql-0.1-193 but didn't hit this issue so far, But still need to continue to reproduce it, more times and compare the old version. keep reproducing. Continue to reproduce 300 times on win2012/win8.1-64 with virtio-win-1.9.12-2.el7.iso and win10-64 with the latest virtio-win-prewhql-193.iso ,still couldn't reproduce this bz. As this bz was not reproduced in recently testing, feel free to close it. (In reply to xiagao from comment #62) > As this bz was not reproduced in recently testing, feel free to close it. Closing based on comment #62 |
