CentOS virt - Apr 2008 - How to clone a guest for cold stand by

Hi,

what would be the shortest and fastest way to clone a e.g. basic Centos 
5 guest for further use? For example I'd like to set up a master 
Mysql-server as a guest an than "clone" two additional slaves.

Which xen configfiles may be edited? Can the config and the filesystem 
simply be copied?


Thanks for suggestions!

Regards

G?tz

I have a lvm "template", i.e. a simple volume with the OS skeleton ( a
minimal install). When I need a new VM I do
- lvcreate newvolume
- mkfs newvolume
- mount template /mnt/source
- mount newvolume /mnt/destination
- cp -a /mnt/source /mnt/destination

wash, rinse, repeat as needed.

cp /etc/xen/template /etc/xen/newVM
vim /etc/xen/newVM

yes.

yes. You want to remove information from the config file that should be 
unique, for instance the UUID. It will then create a new one for you.
