Hi All,
I was trying the VPP first time in my ubuntu 22.04 to make the Linux
control plane work , but I am consistently hitting one or other crash
related to VMXnet3 PMD. I am not sure if this is very unstable or am I
doing something wrong?
DPDK version : 26.02
VPP startup.conf
unix {
nodaemon
cli-listen /run/vpp/cli.sock
full-coredump
log /var/log/vpp/vpp.log
}
api-trace { on }
cpu {
main-core 2
workers 3-5
}
dpdk {
dev 0000:0b:00.0 {
name vpp-eth1
num-rx-queues 1
num-tx-queues 1
# no-rx-interrupts
}
no-multi-seg
}
statseg {
socket-name /run/vpp/stats.sock
}
plugins {
plugin linux_cp_plugin.so { enable }
}
CLI command:
set interface state vpp-eth1 up
lcp create vpp-eth1 host-if eth1
WIth no no-rx-interrupts , I am seeing following crash

Any thoughts?
Thanks,
