Hi I am wondering is there an easy way to configure domU (vm) quickly, atm we are using eg LV (Logical Volumes) to storge root, var and swap for VM and then using disk = [ 'phy:vg/myvmdisk1,sda1,w', ... ,... ] to launch it.
We takes the tar gunzip of file system of root, var of currently running vm and when need arrives we just have to created LVs and untar the achieves and launch the new vm with very little changes.
Only one problem in this approach is that we get little outdated vm which need to update using 'yum'. So is there a way to start new vm fast and using currently updated running vm file system?
Thanks. Askar.
You could use LVM snapshots. They're copy-on-write, so they can be created quickly. Of course, if you start a new VM on a snapshot of a running VM, then the filesystem will not be clean (it will look as though it was from a system that was turned off without being shutdown).
