[one-users] how to use lvm datastore for virtual machine disks

[Denis J. Cirulis]

Two more questions:

1. Can I predefine the size of the vm disk in template, so that if ttylinux
is 40MB big virtual machine disk would be 10G not 40MB ?
2. I have a bunch of already running virtual machines libvirt/kvm, how can
I migrate them to opennebula ?

Thanks a lot for you help!
