Hi-

With respect to the web link
http://wiki.openstack.org/HeterogeneousTileraSupport,

"

For supporting non-x86 architecture (ex. TILERA), Proxy Compute Node should
be designed.
An x86 Proxy Compute Node is connected to the TILEmpower boards through
network. A Proxy Compute Node may handle multiple TILEmpower boards.
TILEmpower boards are connected to the network such that a cloud user can
ssh into them directly after an instance starts on the TILEmpower board. A
TILEmpower board is configured to be tftp-bootable or nfs-bootable. Proxy
Compute Node behaves as the tftp/nfs server for the TILEmpower boards. *After
Proxy Compute node receives instance images from the image server, it wakes
up a TILEmpower board and controls their booting.* Once a TILEmpower board
is booted, Proxy Compute Node doesn't do anything except
terminating/rebooting/power-down/power-up of the board. Once Tilera
instance is running, user can access the TILEmpower board, not Proxy
Compute Node, through ssh. Here, we assume that Proxy Compute Node can
power on/off TILEmpower boards remotely using PDU(Power Distribute Unit).
The block diagram shown below describes the procedure in detail...........

"

In an general environment, Nova-compute with the help of Nova-scheduler,
boots an image instance at Server-2/ESSEX-2/Nova-agent server.

 Can any one help me in understanding the above colored lines ....

Thanking you...
