Notes for upgrading from older versions[]

Upgrading from coLinux 0.7.3 and before[]

  • Some dev distries increase eth1, eth2, eth3, ... on every boot. Typicaly have no network, but can see it with "cat /proc/net/dev". As workarrount set an unique MAC address for all network interfaces in config file. Or disable udev.
Debian: Remove all entries from /etc/udev/rules.d/z25_persistent-net.rules

Upgrading from coLinux 0.6.4 and before[]

  • XML config files have been removed. Use the command-line syntax in a name=value per line plain text file instead (see colinux-daemon.txt):
  • Replace the -c name with "@name" as parameter for colinux-daemon.
  • Locate for tool "colinux-xml2cfg", a XML to CFG converter for coLinux on SF or here
  • The file initrd contains no modules. Modules are only in the file vmlinux-modules.tar.gz. The initrd extracts modules over device cofs31 automaticly, if you configure it as initrd=initrd.gz in config file. After modules are installed, you can remove the initrd from config.

Upgrading from coLinux 0.6.1 and before[]

  • Gentoo users need to be careful, Gentoo tends to use devfs when upgrading from 0.6.1 and so block device names change from cobdX to cobd/X and render the image unbootable. For more details and solutions see the 2.6 related information on the Wiki.
