Hi. I'm try to write own sheepdog compatible daemon and test it with qemu. Sometimes ago in qemu added read write error policy to allow to stop domain or continue or something else. As i see in case of sheepdog this policy is ignored and qemu try to reconnect to sheepdog daemon. If nobody wants i can try to fix this, and if policy is not specified work like now. Where i need to start to easy understand how this works in case of file raw ?
Also i'm fedora user with virt-preview repo and see, that if sheepdog daemon is unavailable 2 or more minutes and started after that qemu crashed. Does i need to retest with latest qemu version? b2587932582333197c88bf663785b19f441989d7 f1af3251f885f3b8adf73ba078500f2eeefbedae 5eceb01adfbe513c0309528293b0b86e32a6e27d qemu-system-x86_64 -machine q35 -accel kvm -m 512M -vnc 0.0.0.0:1 -device virtio-scsi-pci,id=scsi0 -drive aio=native,rerror=stop,werror=stop,if=none,format=raw,id=drive-scsi-disk0,cache=none,file=sheepdog:test,discard=unmap,detect-zeroes=off -device scsi-hd,bus=scsi0.0,drive=drive-scsi-disk0,id=device-scsi-disk0 qemu-system-x86_64: failed to get the header, Invalid argument qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: failed to send a req, Bad file descriptor qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: Failed to connect socket: Connection refused qemu-system-x86_64: /builddir/build/BUILD/qemu-2.9.0/util/iov.c:167: iov_send_recv: Assertion `niov < iov_cnt' failed.
