Description Mihail Stanciu 2015-10-27 12:37:48 UTC

Tested on master: 505a82673ac2487df5ea343a6422c2fc47018831
OS affected: OpenSUSE 13.2

All sanity tests failed on OpenSUSE AB with following error:


| qemu-system-arm: -net tap,vlan=0,ifname=tap0,script=no,downscript=no: could not configure /dev/net/tun (tap0): Operation not permitted
| Releasing lockfile of preconfigured tap device 'tap0'
| stty: standard input: Inappropriate ioctl for device
| stty: standard input: Inappropriate ioctl for device

All taps are pre-generated on system startup with runqemu-gen-tapdevs script.

Investigation started.

Comment 2 Mihail Stanciu 2015-11-02 12:33:45 UTC

Possible root cause:
Taps were being created by default as belonging to user autobuilder, but the group used in creation did not exist. Modified tap creation script to use the default autobuilder group for OpenSUSE (users - gid 100) and the problem seems to have gone away.

Currently re-running a full test pass on this machine.
Will update further once run is complete.

This has fixed the problem.
Marking as NOTABUG.
