#Plan 9 installs easily under current versions of Qemu and KVM. Here
#are some detailed instructions. See [plan9 on qemu on windows] for
#installing on Windows with TAP networking.
#
#INSTALLATION
#
#First install qemu. Optionally, you can install kqemu also. This
#will give a significant speed advantage. To use KVM, replace calls
#to qemu by calls to kvm.
#
#Create a disk image, 2Gbytes should be plenty for a testing install.
#
#! qemu-img create -f qcow2 Plan9.qcow2.img 2G
#
#If you are creating a vm for long-term use and not simply
#exploration or testing, you probably want a larger image size and to
#use the .raw format. Install the image. You probably want to do a
#simple fossil only install rather than a venti+fossil one---read the
#papers to discover what the difference is.
#
#During the install, remember that the default hard drive file is at
#/dev/sdC0 and the cdrom is at /dev/sdD0. The distribution is located
#at /dev/sdD0/data in the / directory. You will be installing to
#/dev/sdC0/plan9 after the partition is created and you want to use
#the plan 9 mbr and plan9 bootup. The install may proceed slowly
#depending on host os and qemu version and the availability of DMA
#for disk access. (Is this still true? Installing under kvm was not
#that slow for me recently. --rob)
#
#! qemu -hda Plan9.qcow2.img -cdrom plan9.iso -boot d
#
#During the install you will be prompted for your monitor type.
#Recent qemu versions work with the default setting of xga, using
#-vga std. For older versions, you may need to ---enter:
#
#! vesa
#
#Once you have finished the installation you can boot this image with
#just:
#
#! qemu Plan9.qcow2.img;
#
#Once booted you can list the available VESA VGA modes:
#
#! aux/vga -m vesa -p
#
#Before exiting qemu, halt the plan9 filesystem so it can sync its
#disks:
#
#! echo 'fsys main sync' >>/srv/fscons
#! sleep 5
#! echo 'fsys main halt' >>/srv/fscons
#
#( The standard fshalt script as of 2013 seems to be broken in Qemu.
#When fshalt changes vga mode to text, many versions of Qemu
#experience bugs. )
#
#PRE-INSTALLED QEMU IMAGES
#
#The following images are default installs prepared under qemu-0.9.1,
#using a plan9.iso from January, 2011:
#
#[fossil | http://plan9.stanleylieber.com/qemu/fossil.qcow2.img.bz2]
#
#[fossil+venti |
#http://plan9.stanleylieber.com/qemu/fossil+venti.qcow2.img.bz2]
#
#NETWORKING
#
#Basic networking (without requiring root access) can be enabled with:
#
#! qemu -hda Plan9.qcow2.img -net nic -net user
#
#By default, the guest system (Plan 9) will be able to access the
#host system with IP address 10.0.2.2. See qemu(1) for more details.
#
#If you are running a (standalone) CPU server, you need to open up
#some ports for the host system:
#
#! qemu -hda Plan9.qcow2.img -net nic \
#! -net user,hostfwd=tcp:127.0.0.1:17567-:567,hostfwd=tcp:127.0.0.1:17010-:17010
#
#This enables the host system to drawterm into localhost. Note that
#qemu listens on port 17567 instead of 567 (auth server) because 567
#is a privileged port on Unix.
#
#HARD DRIVE FILE PERFORMANCE
#
#For better disk performance than the -hda parameter, try specifying
#drives like this:
#
#! qemu -drive file=plan9.raw,media=disk,index=0,cache=writeback
#
#Writeback caching is slightly less safe but offers considerably
#better performance, as tested in current linux distros. (2013).
#
#I would also recommend using .raw format images rather than .qcow.
#The smaller size of qcows is entirely short-term; long term they
#grow without limit for every disk operation. .raw format is more
#portable and will not grow beyond the given size.
#
#DEALING WITH PRIVILEGED PORTS
#
#Traditional unix reserves ports 1-1024 to root which is
#inconvenient. To provide access to these ports and avoid running vms
#as root, make use of the os-level port redirection in your host os.
#Here is an example for linux using iptables to redirect the most
#important Plan 9 specific ports, 9p port 564 and authsrv port 567:
#
#! iptables -t nat -A PREROUTING -p tcp --dport 567 -j REDIRECT --to-port 2567
#! iptables -t nat -A OUTPUT -o lo -p tcp --dport 567 -j REDIRECT --to-port 2567
#! iptables -t nat -A PREROUTING -p tcp --dport 564 -j REDIRECT --to-port 2564
#! iptables -t nat -A OUTPUT -o lo -p tcp --dport 564 -j REDIRECT --to-port 2564
#
#This is combined with qemu port redirection which takes the
#redirected port from the host and sends it to the normal Plan 9 port
#inside qemu. An example qemu command line for a combined
#cpu/file/auth server to be used after the iptables redirections
#above:
#
#! qemu [...] -net nic -net user,hostfwd=tcp::17007-:17007,hostfwd=tcp::17010-:17010,hostfwd=tcp::2564-:564,hostfwd=tcp::2567-:567
#
#NETWORK TROUBLESHOOTING
#
#Some versions of Qemu have a bug in the Qemu dns server. If you
#experience dns failures in qemu when using dhcp, trying adding a
#line like
#
#! DNSSERVER=8.8.8.8 # google public dns
#
#to your termrc or cpurc. When setting up Qemus to provide cpu access
#or other services, it is often important to check the network
#environment on the host box. Commands in the host os such as:
#
#! netstat -tnlp # numeric listing of all programs listening on tcp ports
#
#are helpful to verify that the qemu is listening on the right
#service ports and other programs are not competing for access. Some
#other things to remember are the question of the ip Qemu provides to
#the machine (10.0.2.15) in its standard nat mode and that dialing
#loopback vs numeric ips on the host and guest may interact in
#unexpected ways. Some users prefer to configure virtual bridges or
#vlan interfaces to provide VMs with independent ips. This is highly
#os and distribution specific; find a guide that works for your setup.
