Hi Dan,
I have 15 ovirt hosts running vdsm, and no problem with el6 ones.
However, all of my el7 hosts (freshly installed because provided with no
OS) meet this issue.
I don't need ipv6 for the moment (maybe in 10 years :)), so the best way
is to deactivate it.
As I said, the issue seems to come frome ipv6 dns resolution, so it
could be a DNS issue...
Something else : before registering the el7 hosts, I use nmtui so as to
configure a few network feature, like vlan for the upcoming ovirmgmt
network. I didn't take care of the default options in this ui, but maybe
something is related to ipv6 here.

To the best of my knowledge, it was never reported, and certainly was
never fixed.
At the moment, I'm not yet sure that there's something to fix in oVirt:
Like Diid, I wouldn't want to disable ipv6 on all hosts. I'd rather
understand why Nathanaël's ipv6 dns lookup fail, and solve this specific
bug.
Nathanaël, could you provide more details on the underlying bug? Do you
think that it is somehow related to ovirt?
