[Users] Questions about oVirt and possible API bug

[Andrey Falko]

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 am 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 whether oVirt-engine is designed with redundancy in mind. Is oVirt capable of 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 wrong? The host is in maintenance mode, I do not see anything in the engine logs after I run the command.

Thanks,
Andrey
