[root at xen ~]# virt-install -p ERROR A name is required for the virtual machine. [root at xen ~]# virt-install -p -n newdom ERROR Memory amount is required for the virtual machine. [root at xen ~]# virt-install -p -n newdom -r 256 ERROR A disk must be specified (use --nodisks to override) So it goes on... I suppose once you plough through all the options and save the whole command somewhere, then it is trivial to create new ones, but I got the impression that it was interactive for any missing options.

Well, if you have done such tests, please do share... especially on the xen-users list, as there are far more competent Xen-ers to discuss your findings than me. > You want to use LVM or remote storage for real world usage, anyway, but that > wasn't the task outlined by the OP. File based domains initially seemed the simplest way for me, but after a while I concluded they were a but of a pain actually, so indeed I do stick with LVs.
