Re: How to set an Openstack host id in the NovaTemplateOptions ?

[Reka Thirunavukkarasu <re...@wso2.com>]

Hi

Would the templateBuilder().locationId(Stirng) in ComputeService be used
for this particular case where we need to provide our own availability zone
when starting an instance via jclouds? So that, we can overwrite the
location with our preferred one.

I have tested it for ec2 with availability zone and it is working fine. But
when i tested with openstack, i can't find the correct locations as from
listAssignableLocations() in ComputeService. listAssignableLocations()
always returns openstack region even though there are multiple zone got
configured in openstack. Shouldn't the listAssignableLocations return all
the available zone in openstack? Is this purposely done for openstack as to
return only the region from listAssignableLocations() or Am i missing any
configuration in openstack while configuring the availability zone?

Thanks,
Reka
