Also - is there a bugID for this new issue?
The one I quoted is supposed to only affect non-existent device names.
Why is this affecting valid device names as well, and only in the VDSM
context?
Antonio may correct me here, but I believe it's caused by vdsm using
libnl-1.x and py-ethtool using libnl3. We've discovered an issue with
this combination, where libnl-1.x is able to invalidate the netlink
socket libnl3 gives py-ethtool; rendering py-ethtool useless.
This issue is somewhat tracked in this bz:
<https://bugzilla.redhat.com/show_bug.cgi?id=1078312>
This is actually quite a delicate issue, as I believe there are some
fixes in vdsm, py-ethtool have some patches to improve the error
handling (which should help vdsm too) and we're waiting for an official
libnl3 update to tackle the socket handling better.
I have hopes that once the libnl3 fixes gets out, much of this will be
solved.
