You will need to do a vgscan to scan for the LVM volumn you created.
Once scanned, you can then mount the file system(s) there, either using
the mapper files (/dev/mapper/volumegroup-volumn) or the mount labels
(LABEL=label). If this was a stock CentOS install, the root file system
will be labeled '/' and the /boot file system will be labeled '/boot':
mkdir /mnt/sysimage
mount -v LABEL=/ /mnt/sysimage
mount -v LABEL=/boot /mnt/sysimage/boot
