Hi, Zhang:
When I create PVM with: -drive if=virtio,id=primary-disk0,driver=quorum,read-pattern=fifo,vote-threshold=1, children.0.file.filename=... SVM with: -drive if=ide,id=secondary-disk0,file.filename=... I got this ERR: qemu-system-x86_64: block.c:5062: bdrv_detach_aio_context: Assertion `!bs->walking_aio_notifiers' failed. I changed if=virtio to ide on both PVM and SVM, it works fine. When I test failover with: {"execute": "x-colo-lost-heartbeat"} on SVM. I got this ERR: Conflicts with use by a block device as 'root', which does not allow 'resize' on node0.
