dtc_reinstall_os

NAME

dtc_reinstall_os - reinstall an operating system in a VM

SYNOPSIS

dtc_reinstall_os [ -v ] VPS_NUMBER HDD_SIZE MEMORY_SIZE IP_ADDRESS [ DISTRO ] [ lvm|loopback ]

DESCRIPTION

dtc_reinstall_os This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server.

When doing it's setup, dtc_reinstall_os will copy the file /etc/dtc-xen/authorized_keys2 into the VPS's /root/.ssh/authorized_keys2, so the administrator has access to the VPS without the need of shutting it down. So it's a good idea to copy your shh public key in /etc/dtc-xen/authorized_keys2.

VPS_NUMBER has to be a number between 01 and 19

HDD_SIZE is not really used, but it's keeped to be consistant with dtc_setup_vps_disk

MEMORY_SIZE is the amount of memory in mega bytes that you want to have setup in the Xen startup file for this VPS

IP_ADDRESS is a list of IPs that you want to be set in the VM's startup file and in the VM's configuration. Note that the IPs have to be separated by spaces, and thus you might want to use single quotes like this: '1.2.3.4 1.2.3.5'. Note that only the first IP will be set in the VM's configuration, but the list will be set in the Xen startup file so you can use the anti-spoofing facilities of Xen if you need it (with untrusted users / unknown customers for example).

[ DISTRO ] is an optional parameter that can be debian, centos, gentoo or netbsd. If ommited it will use debian as default. Note that for centos and gentoo, you need to have the install files downloaded in /usr/src/gentoo: portage-latest.tar.bz2 and stage3-amd64-2006.1.tar.bz2 (if using amd64 arch) or stage3-x86-2006.1.tar.bz2 (if using i[3456]86 arch).

[ lvm | loopback ] You can then specify lvm or loopback. Currently the only value the script compares to is lvm (or anything else), but this might change in the future. If ommited, then lvm loopback is used.

OPTION

For the moment only the option -v is used. Without -v, dtc_reinstall_os normally outputs everything in /xen/XX.stderr and /xen/XX.stdout to keep a log of the installation. With -v, the redirection of standard output and error is not done.

EXAMPLE

dtc_reinstall_os 16 15360 256 '66.2.45.2 66.2.45.3' debian lvm

This will setup the VM called xen16, build it's startup file in /etc/xen/xen16 with a vif containing ip=66.2.45.2 66.2.45.3 and 256 MB of RAM, setting-up a debian stable operating system with 66.2.45.2 setup as eth0 IP address (66.2.45.3 is to be added later on manually in /etc/network/interfaces later).
