Installing in Xen 3.0 D1255352648 Amiller #These instructions are for Xen 3. See [installing in xen] for Xen #2.0 instructions. # #INSTALL XEN # # * Grab xen and install it. Releases 3.0.2 - 3.0.4 and 3.2.1 are # known to work. # * Start xend #! xend start # #CREATE A PLAN9 DOMAIN # # * setup your directory with your kernels and the plan9 install cd. # You can get the 9xenpcf, 9xenpccpuf and 9xeninst kernels from # /n/sources/xen/xen3. If your Xen hypervisor runs in PAE mode, use # 9xenpcf-pae, 9xenpccpuf-pae and 9xeninst-pae instead. The install # CD is available at the Plan9 website. #! linux$ mkdir /usr/xen9 #! linux$ cd /usr/xen9 #! linux$ mv /somepath/9xeninst.gz . #! linux$ mv /somepath/9xenpcf.gz . #! linux$ mv /somepath/9xenpccpuf.gz . #! 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.gz" #! memory = 96 #! name = "plan9" #! vif = [ 'mac=aa:00:10:00:00:10' ] #! disk = [ 'file:/usr/xen9/plan9.img,sda,w', #! 'file:/usr/xen9/plan9.iso,sdb,r' ] #! restart = 'never' #! #! # 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. The cdrom is on sd01 # and your disk is on sd00. Don't worry about spurious error messages # like this: #! dev 3 sector xx, write: 0, should be 4608 #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 9xenpcf kernel (for a terminal) or 9xenpccpuf kernel # (for a cpu server) instead of the 9xeninst kernel. The extra # arguments provide the name of the fossil disk partition: #! linux$ cat > /etc/xen/plan9 #! kernel = "/usr/xen9/9xenpcf.gz" #! memory = 96 #! name = "plan9" #! vif = [ 'mac=aa:00:10:00:00:10' ] #! disk = [ 'file:/usr/xen9/plan9.img,sda,w' ] #! restart = 'never' #! #! # This is the equivalent of plan9.ini: #! extra=""" #! bootargs=local!#S/sd00/fossil #! """ #! ^D #! linux$ xm create plan9 -c # # * you'll want to grab the xen bits from /n/sources/xen/xen3/9 and # put them in /sys/src/9. To rebuild your kernel, first bind or copy # the xen/include/public directory from your Xen3 source distribution # to /sys/src/9/xen3/xen-public. Then do #! % cd /sys/src/9/xen3 && mk 'CONF=xenpcf' # #To build a kernel to run in PAE mode, add 'PAE=yes' to the mk #command (or edit the mkfile to make it the default). #
