you can use vppctl show log to display more startup meesage.
VMXNET3 need load vmxnet3_plugin.so.

Subject: [vpp-dev] VPP Hardware Interface Output show Carrier Down
Hi,
We are observing the state of the vpp interface as carrier down in command
vppctl show hardware output. This is observed while starting the vpp:
vppctl show hardware output:
==========================
device_c/0/0 2 down device_c/0/0
Link speed: 10 Gbps
Ethernet address 00:50:56:01:5c:63
VMware VMXNET3

Errors:

We are suspecting the following reasons:
1) Any issue with vfio-pci driver while unloading and loading again?
2) Any corruption is happening during initialization?
I am attaching the startup.conf and vppctl command output files with this mail:
Can anybody suggest a way to resolve this issue?
Thanks,
Sunil Kumar
