Description of problem: It get following error when install windows guest on vhost-user-blk-pci device (qemu) qemu-storage-daemon: vu_panic: remapping queue 0 for new memory region qemu-kvm: Unexpected end-of-file before all data were read qemu-kvm: Failed to read msg header. Read 0 instead of 12. Original request 0. qemu-kvm: vhost_set_mem_table failed: Interrupted system call (4) qemu-kvm: Failed to set msg fds. qemu-kvm: vhost VQ 0 ring restore failed: -1: Transport endpoint is not connected (107) Version-Release number of selected component (if applicable): Red Hat Enterprise Linux release 9.2 Beta (Plow) 5.14.0-191.el9.x86_64 qemu-kvm-7.1.0-5.el9.x86_64 seabios-bin-1.16.0-4.el9.noarch (Many qemu find same issue , it look likes irrelevant with qemu) How reproducible: 100% Steps to Reproduce: 1.
