Hi all,
I hava some doubts about creating virtual disks under qemu/kvm:
a) is it possible to share disks between virtual guests like vmware
server, esx and xen does?? for example to setup a virtual cluster with
two or more nodes using Red Hat Cluster Suite.
b) Can I split virtual disks with some determined length? For example
create an 8 GB virtual disk split on 2GB files with or without
allocating all disk space ...
Many thanks.

Yes. Be sure to use raw files with cache=none.

It's possible with device-mapper and loopback but I wouldn't recommend it.
