Is this a variation of Bug 1850412, which is about to be closed as invalid? (In reply to Ademar Reis from comment #1) > Is this a variation of Bug 1850412, which is about to be closed as invalid? Bug 1850412 related to hotunplug multifunction disk. this bug is similar as Bug 1810858. It is old issue. 1810858 is for single disk hotunplug and can not reproduce on recent version. Hit same issue on 4.18.0-226.el8.x86_64 qemu-kvm-core-4.2.0-30.module+el8.3.0+7298+c26a06b8.x86_64 seabios-1.13.0-1.module+el8.3.0+6423+e4cb6418.x86_64 It may reproduced via: python ConfigTest.py --testcase=block_hotplug.block_virtio.fmt_qcow2.default.with_plug.default.multi_pci.q35 --iothread_scheme=roundrobin --nr_iothreads=2 --platform=x86_64 --guestname=Win2019 --driveformat=virtio_blk --nicmodel=virtio_net --imageformat=qcow2 --machines=q35 --customsparams="image_aio=threads\ncd_format=ide" Hit same issue on win2019

Bulk update: Move RHEL-AV bugs to RHEL9. If necessary to resolve in RHEL8, then clone to the current RHEL8 release. Hit the same issue with virtio-scsi-pci on RHEL9 host. Guest os: Win8.1-64 kernel-5.14.0-10.el9.x86_64 qemu-kvm-6.1.0-5.el9.x86_64 virtio-win-prewhql-0.1-214 seabios-bin-1.14.0-7.el9.noarch reproduced on automation: python ConfigTest.py --testcase=block_hotplug.block_scsi.fmt_qcow2.with_plug.with_reboot.one_pci --platform=x86_64 --guestname=Win8..1 --driveformat=virtio_scsi --machines=q35 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. |
