[dpdk-dev] Will huge page have negative effect on guest vm in qemu enviroment?

[Sam]

Hi all,

We plan to use DPDK on HP host machine with several core and big memory. We
plan to use qemu-kvm enviroment. The host will carry 4 or more guest vm and
1 ovs.

Ovs-dpdk is much faster then normal ovs, but to use ovs-dpdk, we have to
enable huge page globally.

My question is, will huge page enabled globally have negative effect on
guest vm's memory orperate or something? If it is, how to prevent this, or
could I enable huge page on some core or enable huge page for a part of
memory?

Thank you~
