Good Day everyone, Im deploying openstack following packstack rdo tutorial (via advance network). My spec (only for presentation before i got approval from my company to upgrade): Controller: 2 Core, 6gb ram Compute 1: 4 Core, 4gb ram Compute 2: 2 Core, 6gb ram

I can only launch two m1.small flavored instance in compute 1, and four m1.medium in compute 2. I can't launch more spec than that. and i also can't launch instance with higher flavor after i removed those instances. If i'm not mistaken, vcpu and ram default allocation is 16:1 and 1.5:1. I would like to launch an instance that use the maximum resource. at least 6 core, 10gb ram (the higher the better). Can anyone guide me on this?

2018-06-24 19:19:03 -0500 asked a question why i can launch two 4 vcpu instance but not one 8 vcpu instance?

Good day everyone, Im new to openstack. i looked tutorial on installing openstack (packstack) and connect the instance with internet following tutorials here: (

I've setup openstack using 1 controller node [2cpu,6gb ram, 100+ gb space] and 2 compute node [4cpu, 8gb ram, 1Tb space][2cpu,6gb ram, 271gb space]. #my controller node does not include as compute node.

My problem is i can't launch an instance with specs higher than 4 vcpu, 4 gb ram, 80gb disk. I want to setup a single instance that combine both my compute nodes with specs of 8vcpu,10gb ram, 1tb space.

However, i can launch two instance with specs of 4 vcpu, 4 gb ram, 80gb (feels weird) but not a single 8vcpu,10gb ram, 1tb space instance. (with error code 500)

Can anyone help me on this?
