No I'm not using python openstakclient. Just using curl.

I was not aware of this syntax. See https://docs.openstack.org/nova/lates... for more info and alternatives.

Note, however, that you must be admin to select a host this way (except if you tweak the policy).

You can also use the direct API (what you call "curl") to submit such a request. Set availability_zone or hypervisor_hostname; see https://docs.openstack.org/api-ref/co....

availability_zone is like host_group. But I want to select particular Host inside availability_zone

Thanks for your reply! I'm not concern about High Availability. My environment is different and they just need an option to select a host while creating a VM. curl -l -k -i -X POST https://${IP}:5000/powervc/openstack/compute/v2/${PROJECTID}/servers -H "X-Auth-Token:$INSERTTOKEN" -H "Content-Type:

application/jsaon" -d '{"server":{ "flavorRef":"'"$FLAVORID"'", "name": "'"$NEWVNMNAME"'", "networkId": "'"$NETWORKID"'", "imageRef": "'"$IMAGEID"'", "networks":[{"uuid"; "'"$NETWORKID"'"}], "powervm:storage_connectivity_group:; "'"$STORAGE_CONNECTIVITY_GROUP"'"}}'

I can select the Host using GUI of PowerVC. So my guess is there should be some option while creating VM via cli.

Yes, one of the above options.

I created host aggregate but when I try to add the host to the aggregate I get error - "The host cannot be added to more than one aggregate" Code -400
