[Environment]

DPDK version: Use make showversion or for a non-released version: git remot=
e -v
&& git show-ref --heads
23.07.0-rc0
Other software versions: QEMU-8.0.0
OS: Ubuntu 22.04.2 LTS/Linux 5.15.45-051545-generic
Compiler: gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04)

NIC firmware: ice-1.11.14/4.20 0x80017785 1.3346.0

[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.

1.Bind 1 NIC port to vfio-pci driver:

dpdk-devbind.py --force --bind=3Dvfio-pci 0000:4b:00.0

2.Start dpdk-testpmd as back-end:

x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -l 1-5 -n 8 -a 0000:4b:00.0  \
--vdev net_vhost0,iface=3D/root/dpdk/vhost-net,queues=3D4    \
-- -i --nb-cores=3D4 --rxq=3D4 --txq=3D4 --rss-ip
testpmd>start

3.Start VM with QEMU-8.0.0 as front-end:

taskset -c 20,21,22,23,24,25,26,27 /home/QEMU/qemu-8.0.0/bin/qemu-system-x8=
6_64
 -name vm0 -enable-kvm -pidfile /tmp/.vm0.pid \
-daemonize -monitor unix:/tmp/vm0_monitor.sock,server,nowait -netdev
user,id=3Dnttsip1,hostfwd=3Dtcp:10.239.252.245:6000-:22 -device
e1000,netdev=3Dnttsip1  \
-cpu host -smp 4 -m 8192 -object

ce
virtio-serial -device
virtserialport,chardev=3Dvm0_qga0,name=3Dorg.qemu.guest_agent.0 -vnc :4 \
-drive file=3D/home/image/ubuntu2004.img -chardev
socket,id=3Dchar0,path=3D/root/dpdk/vhost-net -netdev
type=3Dvhost-user,id=3Dnetdev0,chardev=3Dchar0,vhostforce,queues=3D4 \
-device

ue,mrg_rxbuf=3Don,csum=3Don,mq=3Don,vectors=3D10

4.SSH connect VM and build dpdk-l3fwd-power APP, and then start
dpdk-l3fwd-power:

CC=3Dgcc meson -Denable_kmods=3DTrue -Dlibdir=3Dlib  --default-library=3Dst=
atic
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
meson configure -Dexamples=3Dl3fwd-power x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc

./x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power  -c 0xf -n 4
--log-level=3D'user1,7' -- -p 1 -P --config '(0,0,0),(0,1,1),(0,2,2),(0,3,3=
)'
--no-numa  --parse-ptype --interrupt-only
Show the output from the previous commands.

The VM will crash, when start dpdk-l3fwd-power APP in VM with QEMU-8.0.0, a=
nd
it works well when start VM with other QEMU version less than QEMU-8.0.0.

[Expected Result]
Start dpdk-l3fwd-power APP in VM with QEMU-8.0.0 works well, no crash occur=
ed.
Regression
Is this issue a regression: (Y/N) N

Maybe this is an Compatibility Issues with QEMU-8.0.0.
