Bug Description
Env: ISO built on 11 April. Simplex AIO on libvirt VM, vswitch_type = ovs-dpdk
After deployment/apply, the VM is slow, and finally doesn't response.
Reboot doesn't resolve this problem.
After investigation, I find this happens because of low memory available.
I find that 6554 x 2M hugepages are reserved, it's more than 10GB memory.
I can see only 512 x 2M is used by ovs-dpdk. I lowered the hugepages to 1024, no such issue anymore.

StarlingX is designed by default to allocate all memory as 2M hugepages minus the memory reserved for the platform (including ovs-dpdk). Users are expected to use servers that have enough memory to run a StarlingX software load.
