This is in fact the issue recorded in https://bugzilla.redhat.com/show_bug.cgi?id=1950192#c12, we found it during the early testing of qemu-kvm-6.0.0 on RHEL9.0.0. It should be the same cause of bz1950192 since the core dump info is the same.

I agree, this is likely a duplicate ... to be sure, bfu, could you please double-check whether you could trigger this issue with the Clang build of qemu-kvm, too? Version-Release number of selected component (if applicable): host kernel:5.14.0-0.rc4.35.el9.s390x qemu version: qemu-kvm-6.0.0-12.el9.s390x guest kernel: 5.14.0-0.rc4.35.el9.s390x As the test result of PASS 1-Host_RHEL.m9.u0.nographic.qcow2.virtio_scsi.up.virtio_net.Guest.RHEL.9.0.0.s390x.io-github-autotest-qemu.blockdev_mirror_vm_reboot.s390-virtio, close this bug as duplicate since the root cause is same as https://bugzilla.redhat.com/show_bug.cgi?id=1950192 *** This bug has been marked as a duplicate of bug 1950192 *** |
