I figured out the problem with the ovirt-shell. I forgot to inject the stor=
age-path parameter...not sure if that is supposed to be required or not.

Subject: Questions about oVirt and possible API bug
Hi everyone,
One of the requirements behind the system that I am attempting to build is =
that there should be no local storage. I've noticed that I cannot add local=
storage hosts to the same datacenter and cluster. It seems awkward to have=
a 1:1:1 ratio of datacenter to cluster to host. Is there anything that I a=
m missing or is there a reason for why this is the design in ovirt?
I plan to use the system to provide a service where end-users will make API=
calls to create and delete VMs. It will be critical that oVirt-engine not =
be a single-point of failure. I can't seem to find much information about w=
hether oVirt-engine is designed with redundancy in mind. Is oVirt capable o=
f a failover or an active-active configuration?
Finally, I am attempting to automate registration of hosts to oVirt and am =
hitting this when I try to add a local storage domain:
[oVirt shell (connected)]# create storagedomain --host test1 --type "Data (=
Master)" --storage-type "Local on host"
unknown error: 'str' object has no attribute 'export'
Is this a bug with ovirt-shell that I should file or am I doing something w=
rong? The host is in maintenance mode, I do not see anything in the engine =
logs after I run the command.
Thanks,
Andrey

[Users] permanent vnc password and custom properties
by Michal Kopacki
Any thoughts how to set vnc password permanently (without any scripts
outside ovirt). ?
Now I use cli command such:
vdsClient -s 0 setVmTicket 75c42e2e-ac28-45ae-9c78-2e4f68ee9c07 <pass>
3600 keep
But it's not so convenient.
Second question is how to use "Custom properties" box - how should
command/value looks like ?

Re: [Users] CLI: can't attach storagedomain
by Li, David
Omer,
My storage domain was in "unattached" stage. So I ran the following CLI to attach it to the data center:
[oVirt shell (connected)]# create storagedomain --name "fc16-lid-engine_iso-domain" --datacenter-identifier "ac2690e4-72b2-11e1-882d-000c29bf47ca"
unknown error:
status: 400
reason: Bad Request
detail: [Cannot attach Storage Domain.]
The vdsm.log shows nothing specific to this but periodically spits out the following. I am not sure if this is relevant.

i dont think so,
looks like the problem is with your host, which fails to mount this dir.
maybe attach the vdsm.log for this host and for that action (look for the validateStorageServerConnection that fails.)

[Users] Configuring MTU
by Nathan Stratton
Is there a way to configure MTU on a guest by guest basis? All our bond
interfaces are configured as 9000 byte MTU, but we have a few guests that
don't support that and need 1500 byte setting.
