[coLinux-users] Message based mechanism

[anshul m. <ans...@gm...>]

Hi,

I need to implement the suspend / resume mechanism at the VM level and
not specific to any guest OS. (Just like VM-Ware where in we can
suspend and resume any VM).

In CoLinux, linux.sys acts as a virtual layer (Windows kernel mode
driver) that interacts with daemon and linux kernel.

Some basic doubts:
Now suppose user has selected  to suspend coLinux guest, now I am not
clear how will I get that message in linux kernel so that I can
initiate a suspend/resume. Either daemon will capture that request and
then send it to Windows driver (linux.sys) which then sends it to
linux kernel or daemon will capture and directly send to linux kernel.

Further I was just browsing through the code and was wondering if user
gives a shutdown request from the guest OS only (not from VM), then
does this shutdown message or any other message goes to linux.sys or
Windows daemon. I could find a SHUTDOWN message being passed from
Windows daemon back to Linux kernel, why is that required.

Sorry these are some of the basic doubts, but if I can get some
understanding then it will help me to gain insight into the
architecture of Colinux..
