1. Run virt-manager. 1. Double click on localhost(QEMU) 1. click on the New virtual machine icon 1. follow your nose here, using the ISO as the install media, and allocating no less than 2G of disk and 1G of memory. I suggest 4G if you can spare it. |

This page explains how to set up and run Launchpad (for development) inside a LXC.
Why?
Launchpad development setup makes significant changes to your machine; its nice to be unaffected by those except when you are actually doing such development.
Also, launchpad has some limitations on concurrent testing per-machine and so forth - multiple container's can be used to work around this.
Make a LXC
- Install lxc
sudo apt-get install lxc
Work around 800456
sudo apt-get install cgroup-bin
Work around 784093
sudo dd of=/etc/cgconfig.conf << EOF mount { cpu = /sys/fs//cgroup/cpu; cpuacct = /sys/fs/cgroup/cpu; devices = /sys/fs/cgroup/cpu; memory = /sys/fs/cgroup/cpu; } EOF sudo service cgconfig restart
- Create a config for your containers
sudo dd of=/etc/lxc/local.conf << EOF lxc.network.type=veth lxc.network.link=virbr0 lxc.network.flags=up EOF
- Create a container
sudo lxc-create -n lucid-test-lp -t lucid -f /etc/lxc/local.conf
- If you want to use a proxy
sudo http_proxy=http://host:port/ lxc-create -n lucid-test-lp -t lucid -f /etc/lxc/local.conf
- And if you want to set a custom mirror, similar to http_proxy, but set MIRROR= instead.
- Start it
sudo lxc-start -n lucid-test-lp
- Ignore the warning about openssh crashing - it restarts on a later event. The initial credentials are root:root.
- below this is not yet updated from the vm instructions
After its installed, connect to the image and install acpid and openssh-server
- Use ssh-copy-id to copy your public key into the VM.
ssh -A <vm IP address> to connect to the VM.
bzr whoami "Your Name <your.email@example.com>" to set your bzr identity in the VM.
You can now follow the getting-started on LP instructions.
References
See also this email thread about running Launchpad in a virtual machine, and this discussion of the differences between running in a chroot environment and running a VM. Running/RemoteAccess has a discussion for how you can configure the VM to allow the host machine to access the web pages, etc.
Alternatively
You can skip some manual steps of installing from an ISO using a command like this:
sudo ubuntu-vm-builder kvm lucid --domain vm --dest ~/vm/lp-dev \ --hostname lp-dev \ --mem 2048 --cpus 2 \ --components main,universe,multiverse,restricted \ --mirror http://10.113.3.35:3142/mirror.internode.on.net/pub/ubuntu/ubuntu \ --libvirt qemu:///system \ --debug -v \ --ssh-user-key ~/.ssh/id_rsa.pub --ssh-key ~/.ssh/id_rsa.pub \ --rootsize 24000 \ --user $USER
After installation completes, it should show up in your virt-manager menu.
In LXC
It seems like it would be nice to run Launchpad in LXC containers: they should be more efficient than a VM (especially with regard to memory and disk) but more isolated than a chroot. More testing or documentation is needed.
