Vxlan problem - how to debug? [SOLVED]

I’m trying to get VXLAN working (I upgraded to 4.12 and on hosts installed 3.16 kernel and iproute2-ss140804 - which should be imho the only requirements for that) but my VMs are failing to deploy.

Unfortunately error log is kind of cryptic - http://pastebin.com/fLeHsUgp
relevant part seems to be this line:
Fri Mar 27 13:22:25 2015 [Z0][VMM][I]: Command execution fail: /var/tmp/one/vnm/vxlan/post PFZNPjxJRD4zNTk8L0lEPjxERVBMT1lfSUQvPjxURU1QTEFURT48TklDPjxBUl9JRD48IVtDREFUQVswXV0+PC … couple hundreds chars of similar stuff ommited … FM+PC9WTT4= ‘one-359’

(I used the same templates for VM and networks as I used successfully before on OpenNebula 4.10 with 802.1Q , so the only relevant change should be that of network driver on host)

Could you please advise me how to debug it? Getting VXLAN to work would be really useful for me.

Seems to be a problem with your sudo configuration or ipset not installed

Fri Mar 27 13:22:25 2015 [Z0][VMM][I]: sudo: no tty present and no askpass
program specified
Fri Mar 27 13:22:25 2015 [Z0][VMM][E]: post: Command Error: sudo ipset list

To further debug this you can just execute the command on the host (that
with lots of chars…)


You’re awesome, thank you!

I noticed that ipset in log before and installed it, but as it showed in log again, I assumed it failed because some condition before wasn’t met. It never occurred me to try to actually run it as oneadmin, so I didn’t notice it was actually problem with sudo
