Hi all,

my Linux Xen domU machine have its filesystems on LVM volumes provided
by dom0. I wonder what's the overhead of doing this. In my understanding
all disk access must go through dom0 because only that knows about the
LVM layout. Is that correct?

Now I'm lookig for a way to optimize the IO performance for domU:
- Should I allocate more memory in dom0 for it's disk buffers? Are they
involved at all?

- Can I dedicate whole disks (hdb, hdc) to one domU and let it handle
all disk access including LVM itself without involving dom0 at all?

Thanks!

Michal Ludvig
