2. Why?

3. Why?
● Simplicity

4. Why?
● Simplicity
● Performance

5. Why?
● Simplicity
● Performance
● New Possibilities...

6. What is it?

7. What is it?
It's a hypervisor driver for Nova

8. What is it?
It's a hypervisor driver for Nova
like the drivers for
Xen, KVM, LXC, HyperV, etc...

9. What is it?
It's a hypervisor driver for Nova
… but different

10. This is what Nova looks like

11. VM VM
VM VM
Hypervisor
(xen, kvm, lxc, ...)
Nova Compute Agent
Operating System

12. Control plane
VM VM VM VM VM VM
VM VM VM VM VM VM

13. This is what Nova looks like
… on Baremetal

14. Baremetal Compute Agent
PXE
IPMI
Your applications
Operating System

15. Control plane
Baremetal Compute Agent
Apps Apps Apps
OS OS OS

16. Control plane

17. Is there a simpler way?

18. Devstack
Machine images
HW Info
Baremetal
Bootstrap

19. Deployment
(in detail)

20. Bootstrap Node Baremetal Node
“nova boot ...” Fetch deploy
& user images
Build TFTP config
IPMI Power-On
DHCP Request
Deploy Kernel & Ramdisk
Expose disks via iSCSI
User Image written via iSCSI
Reboot command
DHCP Request
User Kernel & Ramdisk
Cloud-Init Control given
to user

21. Future Plans

22. Future Plans
● Improve performance of deploy process

23. Bootstrap Node Baremetal Node
“nova boot ...” Fetch deploy
& machine images ! Not scalable !
Build TFTP config
IPMI Power-On
DHCP Request
Deploy Kernel & Ramdisk
Expose disks via iSCSI
User Image written via iSCSI ! Not scalable !
Reboot command
DHCP Request
User Kernel & Ramdisk
Cloud-Init Control given
to user

24. Bootstrap Node Baremetal Node
“nova boot ...” Fetch deploy image
deploy image
is small
Build TFTP config
IPMI Power-On
DHCP Request
Deploy Kernel & Ramdisk
Partition disks based
on user metadata
distribute
Fetch machine Image the work
Reboot
DHCP Request
User Kernel & Ramdisk
Cloud-Init Control given
to user

25. Future Plans
● Improve performance of deploy process
● Auto-discovery, firmware updates, etc

26. Future Plans
● Improve performance of deploy process
● Auto-discovery, firmware updates, etc
● Better network support w/ Quantum

27. Future Plans
● Improve performance of deploy process
● Auto-discovery, firmware updates, etc
● Better network support w/ Quantum
● Local persistent storage w/ Cinder

28. Future Plans
● Improve performance of deploy process
● Auto-discovery, firmware updates, etc
● Better network support w/ Quantum
● Local persistent storage w/ Cinder
● Orchestration w/ Heat

29. Future Plans
● Improve performance of deploy process
● Auto-discovery, firmware updates, etc
● Better network support w/ Quantum
● Local persistent storage w/ Cinder
● Orchestration w/ Heat
● Openstack on Openstack

30. This is awesome!
How do I test this?

31. Some hardware
+ Flat network (no DHCP)
+ Devstack

32. What if I don't have
a rack in my closet?

33. Mock hardware with VMs!
