Hi all
I am trying to initialize dpdk and while doing that ovs-vswitchd process
crashes with error in log:
What version of OVS and DPDK are you using?
2019-03-18T13:32:41.112Z|00015|dpdk|ERR|EAL: Can only reserve 270 pages
from 512 requested
Current CONFIG_RTE_MAX_MEMSEG=256 is not enough
Please either increase it or request less amount of memory.

I have allocated 512 hugepages which is reflected in /proc/meminfo. But
it also shows none of them are free even after ovs-vswitchd is in
inactive state.
Are you passing any socket memory arguments to OVS DPDK?
If no memory arguments are specified OVS DPDK will request 1024MB per
socket detected on the system it's being deployed on. If this memory is
not available it will fail to initialize.
If you wish to use 512MB then you should specify this with something
like the following:
ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-socket-mem="512"
There's more info available in the OVS Docs
