Test without iothread, also hit this issue. Hum. I didn't realize you could create read-only virtio-pci-blk devices like that. That the VM fails to boot (or has a lot of errors in attempting to boot) does not surprise me in this case -- your VM image almost certainly expects to be able to write to its own /boot and / partitions. ...That said, I have reproduced this crash upstream, so I'll get to it. Good find, thank you. Proposal upstream @ https://lists.gnu.org/archive/html/qemu-devel/2019-05/msg02651.html Fix included in qemu-kvm-rhev-2.12.0-32.el7 Verified with qemu-kvm-rhev-2.12.0-32.el7, the problem has been fixed, so set bug's status to "Verified".
