Xen (XCP-XAPI) on Precise (Ubuntu 12.04)
This page should contain a sequence of operations to install an XCP-XAPI hypervisor on top of Precise, to get started with OpenStack.
Setup base system
Install a minimal system (Press F4 during the CD install)
Select only an OpenSSH Server when asked
Other requirements:
- An empty partition - in my case `/dev/sda7` (should not contain LVM pv s)
- `eth0` connected to a network with a DHCP server
XCP-XAPI with bridge networking
All the following commands must be executed as root. At the moment you need to perform some post install fixes in case of bridge networking.
Instal Packages
Update your system
apt-get update apt-get -y dist-upgrade
Select your desired network configuration, so that it won't be asked. At the moment the installer seems to ignore this bit, but it is useful to avoid popping up the dialog.
echo "xcp-networkd xcp-xapi/networking_type select bridge" | debconf-set-selections
Setup a redirection, to make sure, xen will be booted first.
dpkg-divert --add --rename --divert /etc/grub.d/09_linux_xen /etc/grub.d/20_linux_xen
Install XCP-XAPI
apt-get install -y xcp-xapi
Post Install Fixes
Select xapi as your default toolstack
echo 'TOOLSTACK=xapi' > /etc/default/xen
Change your network configuration to bridge
echo 'bridge' > /etc/xcp/network.conf
Install `qemu-common`, so that the qemu files will end up at `/usr/share/qemu`
apt-get install -y qemu-common
Configure your network temporarily, so that you still have access to the server after reboot. After reboot, we'll configure xapi manage the network for us.
echo 'auto lo' > /etc/network/interfaces echo 'iface lo inet loopback' >> /etc/network/interfaces echo 'auto xenbr0' >> /etc/network/interfaces echo 'iface xenbr0 inet dhcp' >> /etc/network/interfaces echo ' bridge_ports eth0' >> /etc/network/interfaces
Hack xend init script
sed -i "s/\\\$XEND status && return 1/return 0/" /etc/init.d/xend
Disable services
update-rc.d xendomains disable
Disable openvswitch
update-rc.d openvswitch-switch disable
Reboot your server
reboot
Re-configure your network interface (eth0, dhcp)
xe pif-reconfigure-ip uuid=$(xe pif-list device=eth0 --minimal) mode=dhcp echo 'auto lo' > /etc/network/interfaces echo 'iface lo inet loopback' >> /etc/network/interfaces
SR Configuration
Save your desired SR device to a shell variable
SRDEVICE=/dev/sda7
Create an SR from your SRDEVICE
. /etc/xcp/inventory SR=$(xe sr-create \ host-uuid=$INSTALLATION_UUID \ type=ext \ name-label='Local storage' \ device-config:device=$SRDEVICE)
Set the newly created SR to be the pool default
POOL=$(xe pool-list --minimal) xe pool-param-set uuid=$POOL default-SR=$SR
