During boot LVM complains that it can''t find /dev/VolGroup00/LogVol00 and results in a kernel panic. I''m using Dell 1950''s with Dual Xeon 5245''s CPUs and 32GB RAM with the megaraid_sas kernel module.

Re: [Xen-users] Upgrading to Xen 3.1.0 Dom0 on Centos 5
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I''ve had this very same problem, but I couldn''t find a solution, other than to not use LVM, which is what I settled on. I think you should still be able to use LVM, just not for the root device, but I''ve not tested that.
