I like to create several VM's using KVM on a SLES 11 SP1 host. What is better/faster ? Logical volumes are faster. > Install the VM into a file or a logical Volume ? If i chosse to install it into a LV: does the LV needs a Filesystem, and does it has to be mounted ? No, the volume becomes the guest's disk (which it can then paritition, set up logical volumes, and mount filesystems on). > My aim is that i want to create a HA-Cluster. For every service (currently 3) i'd like to create a VM. I want to have two hosts/nodes, both running SLES 11 SP1. I want to use DRBD to replicate the File/LV to the passive node. Do you thing that's a good solution ? > Sure, this can work, just be sure to test it extensively. Roll-your-own solutions often aren't. -- error compiling committee.c: too many arguments to function
