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. Boot QSD
qemu-storage-daemon \
  --chardev socket,path=/tmp/qmp3.sock,server=on,wait=off,id=char1 \
  --monitor chardev=char1 \
  --blockdev driver=file,node-name=file1,filename=$f1 \
  --blockdev driver=raw,node-name=fmt1,file=file1 \
  --export type=vhost-user-blk,id=export1,addr.type=unix,addr.path=/tmp/vhost-user-blk4-2.sock,node-name=fmt1,writable=on,logical-block-size=512,num-queues=1 &

2. Boot VM with vhost-user-blk-pci device and windows iso file

3.wait 30s to load CD iso file


Actual results:
Find error to make installation failed

Expected results:
The install procedure should succeed

Additional info:
1.no issue install Linux 
example: /home/kvm_autotest_root/iso/linux/RHEL7.7-Server-x86_64.iso

2.error msg may disappear after change CPU cmd line to:
-cpu 'host',hv_stimer,hv_synic,hv_vpindex,hv_time,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_frequencies,hv_tlbflush,hv_reenlightenment,hv_stimer_direct,hv_ipi,+kvm_pv_unhalt \
(remove hv_runtime flag)
or
-cpu host
(no additional flag)
