Bug ID: 1236
Summary: [dpdk-23.07]VM crash when start dpdk-l3fwd-power in VM
with QEMU-8.0.0
Product: DPDK
Version: 23.07
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: vhost/virtio
Assignee: dev@dpdk.org
Reporter: weix.ling@intel.com
Target Milestone: ---
[Environment]
DPDK version: Use make showversion or for a non-released version: git remote -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)
Hardware platform: Purley/IceLake etc.
NIC hardware: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz
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=vfio-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=/root/dpdk/vhost-net,queues=4 \
-- -i --nb-cores=4 --rxq=4 --txq=4 --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-x86_64
-name vm0 -enable-kvm -pidfile /tmp/.vm0.pid \
-daemonize -monitor unix:/tmp/vm0_monitor.sock,server,nowait -netdev
user,id=nttsip1,hostfwd=tcp:10.239.252.245:6000-:22 -device
e1000,netdev=nttsip1 \
-cpu host -smp 4 -m 8192 -object
memory-backend-file,id=mem,size=8192M,mem-path=/dev/hugepages,share=on -numa
node,memdev=mem -mem-prealloc \
-chardev socket,path=/tmp/vm0_qga0.sock,server,nowait,id=vm0_qga0 -device
virtio-serial -device
virtserialport,chardev=vm0_qga0,name=org.qemu.guest_agent.0 -vnc :4 \
-drive file=/home/image/ubuntu2004.img -chardev
socket,id=char0,path=/root/dpdk/vhost-net -netdev
type=vhost-user,id=netdev0,chardev=char0,vhostforce,queues=4 \
-device
virtio-net-pci,netdev=netdev0,mac=00:11:22:33:44:55,disable-modern=true,mrg_rxbuf=on,csum=on,mq=on,vectors=10
4.SSH connect VM and build dpdk-l3fwd-power APP, and then start
dpdk-l3fwd-power:
CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=static
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
meson configure -Dexamples=l3fwd-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='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, and
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 occured.
Regression
Is this issue a regression: (Y/N) N
Maybe this is an Compatibility Issues with QEMU-8.0.0.
