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.

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.

...

Which xen configfiles may be edited?

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

...

Can the config and the filesystem simply be copied?

yes.

Thanks, that's realy simple. I'll try it.

regards

Götz
