cpus constraint in runv #581

Closed jovizhangwei closed 7 years ago

jovizhangwei commented 7 years ago

Hi,

I just tried cpu limiting options with runv, it seems runv cannot accept docker options like --cpuset-cpus and --cpus, just want to confirm this constraint. ("docker run -m" is fine)

qemu options

-smp cpus=1,maxcpus=8 -numa node,nodeid=0,cpus=0-7,mem=1024

Why the cpus is always 1?

If this cpu constraint is right, we should write it down in Doc clearly.

Fixed by https://github.com/hyperhq/runv/pull/589. --cpus is rounded up to specify guest CPU number.
