Bojian,
You cannot run linux commands in the vpp debug command line shell (vppctl).
This is incorrect.
vpp# pwd
FileNotFoundError error(2): No such file or directory as:
/dev/shm/vpe-api
From the message below, it looks like uio_pci_generic may not be loaded or
failed.
Process: 3133 ExecStartPre=/sbin/modprobe uio_pci_generic (code=exited,
status=1/FAILURE)
From the linux prompt:
Try:
#lsmod | grep uio
You should see something like:
# lsmod | grep uio_pci_generic
uio_pci_generic 16384 2
uio 20480 5 uio_pci_generic
If you do not,
Try:
#modprobe uio
#modprobe uio_pci_generic
#service vpp restart

hi vpp team
I tried to install vpp onto ubuntu 16.04, and everything looks good when I
followed installation guide from FD.io wiki. but after I complete the
installation and am going to start vpp service, encounter the error message as
below:
cisco@server-1:~$ sudo vppctl
