./onvm/go.sh 1,2,3 1 -s stdout -a 0x7f000000000 stop running

Bug Report

Current Behavior
I try to build a mtcp container on ONVM, but the mmap function failed. I found this issue has been mentioned in mtcp onvm install guides. But when I try this go.sh command, it stops running at "APP: Stats verbosity level = 1" .(in screenshots)

Steps to reproduce
cd /root/openNetVM
./onvm/go.sh 1,2,3 1 -s stdout -a 0x7f000000000

Environment

• OS: Ubuntu 14.04.1 LTS (CloudLab 220g2)
• onvm version: latest ONVM develop branch

Possible Solution
I try to add a cpu mask, and then it can work.
./onvm/go.sh 1,2,3 1 0xF8 -s stdout -a 0x7f000000000

Additional context/Screenshots

To confirm, does this ./onvm/go.sh 1,2,3 1 0xF8 -s stdout -a 0x7f000000000 or even better (./onvm/go.sh 1,2,3 1 0xF8 0 -s stdout -a 0x7f000000000 ) work fine? The mtcp examples don't have the updated onvm_mgr args, the cpu mask for NFs is a required arg. I'll submit a quick pr to mtcp to fix that.

./onvm/go.sh 1,2,3 1 0xF8 0 -s stdout -a 0x7f000000000 doesn't work. I have tested the epserver in opennetvm-dev latest version and it works. (using ./onvm/go.sh 1,2,3 1 0xF8 -s stdout -a 0x7f000000000)

Oh sorry it should be ./onvm/go.sh 1,2,3 1 0 -s stdout -a 0x7f000000000

[koolzz]

Could you verify that one, there is technically no reason to use 0xf8 as mtcp is supposed to do it's own core managing

[XinShuYang]

./onvm/go.sh 1,2,3 1 0 -s stdout -a 0x7f000000000 can start the ONVM, but when I run the mtcp(epserver) it failed with " Cause: There are no cores available for this NF".
Using ./onvm/go.sh 1,2,3 1 0xF8 -s stdout -a 0x7f000000000 doesn't have this problem.

As I see, yeah the standard core allocation does not make sense with this as we're not actually using the cores from the manager argument for mtcp but if there is nothing there the NF initialization complains.

Thank you for testing this! I'll add some notes regarding the issue and submit the mtcp pr

• Submitted a PR for mtcp
• Still need a README note for onvm
