[Xen-devel] One success case on creating multiple domains purely based on Live CD
All,
The following is the steps I followed to create multiple domains
successfully based on Live CD only. Hope it helps!
1) bootstrap the test machine with Live CD, choose the first option in
Grub menu, and login into with root
2) start dhclient and get one availabe IP. Another alternative would be
using ifconfig and ip command
eth0 Link encap:Ethernet HWaddr 00:0C:29:47:F0:A3
inet addr:192.168.1.129 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:44 errors:0 dropped:0 overruns:0 frame:0
TX packets:38 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:5780 (5.6 Kb) TX bytes:5431 (5.3 Kb)
The reason to assign IP to interface is for the purpose of remote
operation and multiple console windows.
3) Login into the Xen Demo CD powered machine, and execute the following
commands. Name this console as console 1
[root@xendemo0 root]# xen_nat_enable
[root@xendemo0 root]# xen_read_console
4) Login into the Xen machine and get another console named 2, execute
[root@xendemo0 root]# xenctl domain new
Domain defaults:
name XenoLinux
size 98304
vifs 1
domainImage /boot/xenolinux.gz
domainInitRD /boot/initrd.gz

rootArgs rw

[root@xendemo0 root]# xenctl domain start -n1

In console 1, you are able to see the output from domain1 kernel
