Redhat VirtIO developers would like to coordinate with Proxmox devs re: "[vioscsi] Reset to device ... system unresponsive"

We’ve seen similar behavior but we only use cache=writeback in our environment for high performance. In our testing, only virtio-scsi versions 0.1.204 and earlier remain stable under high I/O. Anything from 0.1.208 onward becomes unstable during stress and we can easily reproduce instability when running multiple synthetic workloads with DiskSpd. Without cache=writeback, 0.1.208, 0.1.266 and 0.1.271 appear stable but we don't want to give up writeback caching.
