Use Colinux to boot a Linux system on a hard disk

Article Title: Use Colinux to boot a Linux system on a hard disk. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Two systems are installed on the hard disk. One is Windows XP and the other is UBUNTU6.X. switching between the two systems is troublesome. If a VM is too slow to be installed, and it feels a bit itchy and uncomfortable! I want to use two systems together, and I want two systems to separate different partitions independently. After all, sometimes I want a clean and original linux operating system. Seeing colinux can solve my problem! DOIT.

1 download devel-colinux-20071105.exe

2. Download the kernel 2.6.22, compile and install it into the unbuntu

3. Configure the colinux configuration file

For example:

# CoLinux configuration, created by colinux XML2CFG converter v0.1.0

# File: test. cfg

# Linux Kernel file

Kernel = vmlinux

# Initrd file

Initrdw.initrd.gz

# Memory size for coLinux guest

Mem = 256

# Kernel bootparams

Root =/dev/cobd4

# Block devices and image files

Cobd3 = \ Device \ Harddisk0 \ Partition2

Cobd4 = \ Device \ Harddisk0 \ Partition3

# Host filesystem devices

# Networking devices

4. Unzip vmlinux-modules.tar.gz in the colinux installation directory to/lib/modules.

5. Create a linux Device in unbuntu

For I in 0 1 2 3 4 5 6 7 do mknod/dev/cobd $ I B 117 $ after I done is created, modify the/etc/fstab file, copy all the rows in your root partition and swap partition in the file to a new row and copy the corresponding had? Change to codb?

6 boot colinux
