Hi,
Is it possible that you can provide more info about this isuee. I mean: qemu cmdline/libvirt xml, ovs cmdline, guest driver version and etc… Or it’s hard to reproduce the issue.
Thanks,
Chenbo

Subject: Re: [dpdk-dev] [ovs-dev] ovs-vswitchd with DPDK crashed when guest VM restarts network service
Hello,
I am wondering if there was any progress in this topic, we are seeing a very similar issue, where a VM level application restart triggers segmentation fault and failed to allocate MBuf on the host level
CentOS Linux release 7.8.2003 (Core)
dpdk-18.11.5-1.el7_8.x86_64
openvswitch-2.11.0-4.el7.x86_64
libvirt 4.5.0
QEMU 4.5.0 (API)
QEMU 2.12.0
3.10.0-1127.13.1.el7.x86_64
And we get the same crash
#0 0x00007f96cb72e7ee in rte_memcpy_generic () from /lib64/librte_vhost.so.4
#1 0x00007f96cb7350f2 in rte_vhost_dequeue_burst () from /lib64/librte_vhost.so.4

We have tried upgrading host level artifacts:
dpdk-20.11.3-1.el7.x86_64
openvswitch-2.16.1-1.el7.x86_64
With backtrace:
