We need a way to reproduce this outside of the avocado-vt environment, which is challenging to debug. There could be a problem with the image from a previous test, or from different steps performed during the testing.

Hi,Ademar I have tried to manually reproduce this problem, but it's difficult to reproduce. Best regards. LeiYang Hit this issue with automation test. drive_cache = none test case: 020-Host_RHEL.m8.u1.qcow2.virtio_scsi.up.virtio_net.Guest.Win2012.x86_64.r2.io-github-autotest-qemu.virtio_driver_sign_check.with_viostor.virtio_win_iso_media.q35 qemu version: qemu-kvm-4.1.0-5.module+el8.1.0+4076+b5e41ebc.x86_64 Hi,Tingting Mao I verified this bz in the latest qemu package 'qemu-img-4.1.0-10.module+el8.1.0+4234+33aa4f57.x86_64'. There is not reproduce this issue. So could you please test again with latest qemu package?From my point of view, there should be not a bug now. Test Version: rhel810-64-virtio-scsi.qcow Job link: http://10.66.4.244/kvm_autotest_job_log/?jobid=3793056 Thanks, LeiYang From my test, I ran qcow2 loop with 218 cases with win2012 and win2012r automatically. Just hit 1 case failed for cluster leak, and not image corruption. Plus confirmed with xfu, there is no the issue in acceptance test with latest qemu package. So I will close this bug now. Reopen it if anyone who can reproduce it in the future, please. Reproduce this issue with automation test: drive_cache=none test case: 059-Host_RHEL.m8.u2.qcow2.virtio_scsi.up.virtio_net.Guest.RHEL.8.1.0.x86_64.io-github-autotest-qemu.set_link.reboot_system_reset.status_on.q35/ Test version: KVM version: 4.18.0-147.6.el8.x86_64 QEMU version: qemu-kvm-4.1.0-13.module+el8.1.0+4313+ef76ec61.x86_64 Job link: http://10.66.4.244/autotest_static_job_log/3840588/ |
