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 ....
