Hi all,

I'm debugging OVS2.9.0 and DPDK18.02, I found I could not dump DPDK log
like vhost module.

How can I dump DPDK log into files? Thank you~

(Unfortunately) vhost module doesn't register its log type but uses USER1 log
type [1].

Need to set user1 log type to debug, following eal parameter should work:
--log-level="user1,debug"

Same can be done with logging related APIs by application

How to set this param...

I use this, but report me bug:

sudo /usr/local/bin/ovs-vsctl --no-wait set Open_vSwitch .
other_config:dpdk-extra="--log-level=user1,debug -c 0x40004 -n 4
--socket-mem 1024 -w 0000:01:00.0 -w 0000:01:00.1"

Yes, loglevel numbers are converted to more human readable format in this
release, old releases are using numbers.
