I have been given an assignment to "Write a system call as a kernel module". Now as far as I could understand from my reading on the internet, it is not exactly possible to implement a system call as a kernel module, however there are ways to intercept the existing system calls.
I want to implement read-only access to remote disk drive over HTTP in Linux for XenServer and I'm very new to LKM.
XenServer supports sending raw disk image of virtual machine (only sequental access).
I made kernel module which register /dev/vdi device that handle simple request like read/write/getgeo.
I made userspace program that handles access to remove disk and caches that disk locally as the

I am newbie on Kernel Development techniques. I was wondering if there is a way to establish communication between Kernel and Kernel Modules (LKM), once Kernel Modules are dynamically loaded. What I want to do is to call a function from a specific part of the Kernel to send some data, while the kernel module is waiting for it.
On my windows 7 desktop with the help of Vmware workstation (Version 7.1),
created virtual machine and installed Centos 5.7 successfully using ISO image.
Query : Is this possible to upgrade the Centos 5.7 using Centos 5.8 ISO image to Centos version 5.8?.. if yes kindly guide me the procedure to upgrade.
