Virtualize CentOS4
- Create a regular guest
vserver yourguest build ...
- Empty the just created guest
rm -rf /vservers/yourguest/*
- Copy your old server to the previous folder
rsync -rv --progress --partial --exclude '/proc/*' yourguest:/ /vservers/yourguest/ Why yourguest:/ shouldn't that be / ? Answer: You're now on the host server about to copy an existing installation on another hardware. Would suggest "rsync -av --numeric-ids" instead of "rsync -rv" (preserves permissions, timestamps, ...)
guest on the host, not the guest.
- Remove the fstab
rm /vservers/yourguest/etc/fstab
- Remove the services that makes troubles at start
rm /vservers/yourguest/etc/rc.d/init.d/network rm /vservers/yourguest/etc/rc.d/init.d/..... What are the troubled services? What is the minimal setup to make it work? Answer: Any hardware related services will be troubled and should be removed.
- Disable Pam authentification for ssh access
edit /vservers/yourguest/etc/ssh/sshd_config -> (UsePAM no) replace # Listen with Listen yourguestip (this has to been done on the host too is your host ip)
- Remove the useless modules
rm /etc/modprobe.conf Do you mean editing modprobe.conf? Why delete the file? Answer: Probing modules make no sense in a virtual environment.
- Start your vserver !
vserver yourguest start
