Testing virtualization waters. I want to setup a SLES11 SP1 XEN server with a SLES11 SP1 virtual guest that will house a number of databases and other services. Other guests to be installed at a later date. Any advice whether exporting LVMs from Dom0 to the virtual guest is the best way to go for performance and stability or should I configure the LVMs on the guest itself. Any gotchas with either of these scenarios?

In the old environment, the server is a stand-alone SLES11 SP1 with these databases contained in LVMs with no virtualization. The disk is a fibre-channel attached SAN. This SAN will be used in the new setup as well.
