[ovirt-users] Re: clone snapshot of running vm

2018-09-15 Thread fsoyer

Hi guys,
I just have this issue on a fresh 4.2.6 install. The snapshot of a vm  Seems to 
be the same logs in the ui.log (I paste it here to be sure), and unable to 
clone the snapshot. VM on or off doesn't change things. This really seems to be 
a UI issue because when it appends, we can no more create or clone a snapshot 
on any VM : the buttons just do nothing (and no log in the ui.log when we hit 
them). We must reload the ui (F5 or Ctrl-R) to recover the functionnalities.  
Please help us ? Thanks.

It seems like it is a UI bug.

I meant (b). Option (a) is there to apply the same DNS entries over all
hosts for that specific network.
I do not see a problem of using both.
If you add a new host, Engine will read the existing DNS entries from the
host and persist them. (you will see them in the setup-networks window (b)).
Upgraded systems (hosts have been added before DNS configuration was
available) will have it empty and you will need to explicitly set it.

Yes, but one can change the management network (which owns the
default-route).

The DNS entry are supposed to be applied immediately through ifcfg,
rebooting is an precaution to make sure it has been correctly persisted.
And if the management network is not serving VM/s, then no VM evacuation is
needed.

I guess the risk here is the management network editing, which is sensitive
(Engine looses connectivity and unexpected behaviour may occur).
If there is a problem with this scenario, I would consider it a bug.

I could not find such a BZ.

As far as I remember, when adding a host (that reports the nameservers),
the DNS entries learned are added to the Engine config and used when
sending the first setup-networks to VDSM.
But there were several iterations of this flow, perhaps it changed (will
check).
