[Users] Fwd: Adding a bond.vlantag to ovirt-node

[Alex Leonhardt]

Thanks Antoni,

I'll try the above when it's a bit quieter (evening). Also, good to know
that if you put the host in maint that it will pick the changes up :) ...

IMO - the engine should poll the HVs at least once an hour / day to check
if any hardware relevant to it has changed ... :)

Thanks again, I'll update with the result(s) later today.

Alex
