[王志克]

Another question is:
Why “-numa” option is needed to start the VM?

Hi,

I am reading OVS+DPDK, and it said hugetlbfs is needed for networking between VM and OVS. The question is:
1) How to specify the VM memory for other purpose (non networking with OVS Host)? Is it possible to NOT use the hugetlbfs for non networking?
2) If above is yes, what is the proper value for networking memory?
