my grub.conf is as below
kernel       /xen.gz dom0_mem=1024M loglvl=all guest_loglvl=all sync_console console_to_ring com1=115200,8n1 console=vga,com1 lapic=debug apic_verbosity=debug apic=debug iommu=1 msi=1
module       /vmlinuz- ro root=/dev/VolGroup00/LogVol01 console=hvc0 earlyprintk=xen nomodeset initcall_debug debug loglevel=10
module       /initrd-
I tried changing the root=/dev/VolGroup00/LogVol00 as well.
1.  df -h gives me

2.  pvscan gives me

3.  cat /etc/fstab gives mes

I get below message while booting
