I was trying to add scheduler in Xen 3.4.0, and there is some problem with the procedure I added, I know that because I have created a copy of credit scheduler named it as credit_2 (file attached), changed the functions and struct declarations name (as there was conflict with existing credit scheduler), and then did the following:

1. Added a entry for the same in schedule.c file.
2. Added an entry for it in <xensrc>/xen/common/Makefile

I am able to compile and install XEN after that using 'make xen' & 'make install-xen' command but when I boot with the copy of credit scheduler i.e. credit_2. the screen blacks out and system hangs.
I faced same problem while adding my round robin scheduler, till now I had thought that there is a problem in the rr scheduler but now I am sure there is a problem with the procedure.

Please help me in this regard.
