What is it?

It's a hypervisor driver for Nova

It's a hypervisor driver for Nova like the drivers for Xen, KVM, LXC, HyperV, etc...

This is what Nova looks like

Is there a simpler way?

(in detail)

Deployment

Bootstrap Node Baremetal Node

IPMI Power-On

DHCP Request

Deploy Kernel & Ramdisk

Expose disks via iSCSI

User Image written via iSCSI

Reboot command

DHCP Request

User Kernel & Ramdisk

Control givento user

“nova boot ...”

Cloud-Init

Fetch deploy& user images

Build TFTP config

Future Plans

● Improve performance of deploy process

This is awesome!How do I test this?

Some hardware+ Flat network (no DHCP)+ Devstack

What if I don't havea rack in my closet?

Mock hardware with VMs!
