I'm working on OpenStack Cloud. I have two VM's. On both I have installed
CentOS 7. I have setup one VM as the
controller node and the other as the
I have two questions:
- Can I assign more than available physical RAM to a VM? I know it sounds stupid but I have read this on some blog (sorry I don't remember the site address) that if we have a
swap memorydouble the RAM, than we can do this. Is that really true? I never experienced such thing. Nor the Virtual Box permits to do that! But still if there is a way doing this than I'd love to know it.
- Can I use my physical machine as Controller node, while the Compute node still resides on the VM. If yes, than how? can I please have a explanation for this.
