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

[Marlok Tamás]

Just for the record:
You must disable requiretty in /etc/sudoers file (Default !requiretty)

1. Nope, the image size is predefined (as far as I know).
2. Never tried, so there are maybe smarter people to answer that.


Cheers,
tmarlok
