Re: [Xen-users] Multiple lv's for domu

I need a word of an advice. I plan to deploy Xen on LVM.
Is it worth to do for domu's separated logical volumes for /, /usr,
/home, /var, /tmp and swap when all them will be on the same volume
group?
Or should I make only / and swap partitions and don't care about
anything else?
Multiple lv's could be hard for hypervisor admin to manage, but
safer for domu OS, right?
I think you'll get as many opinions as you get answers ! Like so much
else, there's a large element of personal preference.
Personally, I do all the LVM in Dom0 - so I export several volumes to
each DomU and use them raw (ie with no partitioning in DomU). It
makes it a doddle to manage filesystems in Dom0 - though since I got
into that habit I think it's got easier to loopback mount the volume
and then access the partitions within it.
As to how to split the system up - it all depends. I have some
systems with just a single volume. On the other hand, I have other
systems with multiple volumes so as to split volatile or prone to
growth (eg mail stores) data from the rest of the system - mainly to
prevent uncontrolled data growth bringing the whole thing down.
