</div>[root@xen ~]# virt-install -p<br>
ERROR A name is required for the virtual machine.<br>
[root@xen ~]# virt-install -p -n newdom<br>
ERROR Memory amount is required for the virtual machine.<br>
[root@xen ~]# virt-install -p -n newdom -r 256<br>
ERROR A disk must be specified (use --nodisks to override)<br>
<br>
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.<br>
<br>
Perhaps for the benefit of the OP, perhaps you could give a complete known working example.<br>

<br>
</div>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.<br>

<br>
</div>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.<br>
