These instructions are for Xen 2.0. See installing in xen 3.0 for Xen 3.0 instructions.
INSTALL XEN
- Grab xen and install it. The 2.0.5 release is known to work.
- Start xend
xend start
- Configure xen's networking
antispoof=no /etc/xen/scripts/network startNote: I've had trouble with the antispoofing additions to the iptables rules so I leave them out.
- Enable forwarding
linux$ echo 1 >/proc/sys/net/ipv4/ip_forward
CREATE A PLAN9 DOMAIN
- setup your directory with your kernels and the plan9 install cd. You can get the 9xenf and 9xeninst kernels from /n/sources/xen. The install CD is available at the Plan9 website.
linux$ mkdir /usr/xen9 linux$ cd /usr/xen9 linux$ mv /somepath/9xeninst . linux$ mv /somepath/9xenf . linux$ mv /somepath/plan9.iso .
- create a disk image. Here we make a 1GB drive, but you can use any size you like:
linux$ dd if=/dev/zero of=plan9.img seek=$((1024 * 1024 * 1024 - 1)) bs=1 count=1
- create a xen config file for the plan9 installer. Here we use 96MB of RAM, but you can use any amount you like:
linux$ cat > /etc/xen/plan9inst kernel = "/usr/xen9/9xeninst" builder = "plan9" memory = 96 name = "plan9" cpu = -1 nics = 1 vif = [ 'mac=aa:00:10:00:00:10, bridge=xen-br0' ] disk = [ 'file:/usr/xen9/plan9.img,loop0,w', 'file:/usr/xen9/plan9.iso,loop1,r' ] ip = "1.2.3.4/24" # <- IP you will give to xen9 restart = 'never' console = 999 # This is the equivalent of plan9.ini: extra=""" nobootprompt=local!/boot/bzroot bootfile=sd01!cdboot!bootdisk.img """ ^D
- boot the installer and run through the install process. You will be using the console which is a little clunky. (You could also quit the console (^]) and telnet or netcat to port 999 to reach the console, which works a little better). The cdrom is on sd01 and your disk is on sd00. When asked for the location of the archive simply enter "/" for the root of the cdrom. At the end of the install when it asks for a blank floppy simply reboot the machine:
linux$ xm create plan9inst -c ... % inst/textonly ... ^T^Tr <- to reboot when you're done
- create a xen config file for plan9 and boot it. The new config should use the 9xenf kernel instead of the 9xeninst kernel. For the extra arguments specify either no arguments or a nobootprompt=local argument:
linux$ cat > /etc/xen/plan9 kernel = "/usr/xen9/9xenf" builder = "plan9" memory = 96 name = "plan9" cpu = -1 nics = 1 vif = [ 'mac=aa:00:10:00:00:10, bridge=xen-br0' ] disk = [ 'file:/usr/xen9/plan9.img,loop0,w' ] ip = "1.2.3.4/24" # <- IP you will give to xen9 restart = 'never' console = 999 # This is the equivalent of plan9.ini: extra=""" nobootprompt=local """ ^D linux$ xm create plan9 -c
- you'll want to grab the xen bits from /n/sources/xen/9 and put them in /sys/src/9. To rebuild your kernel:
% cd /sys/src/9/xenpc && mk 'CONF=xenf'
