2.6.1 Introduction to BLCR

BLCR is a kernel level package. It must be downloaded and installed from BLCR.

After building and making the package, it must be installed into the kernel with commands as follows. These can be installed into the file /etc/modules but all of the testing was done with explicit invocations of modprobe.

Installing BLCR into the kernel:

# /sbin/insmod /usr/local/lib/blcr/2.6.12-1.234/blcr_imports.ko

# /sbin/insmod /usr/local/lib/blcr/2.6.12-1.234/blcr_vmadump.ko

# /sbin/insmod /usr/local/lib/blcr/2.6.12-1.234/blcr.ko

The BLCR system provides four command line utilities:

cr_checkpoint
cr_info
cr_restart
cr_run
