a centos7 guest system on esxi reboot failed after host power issue,
trying xfs_repair command at first, result shows "could not initialize XFS library" message,
you'll need to do steps as following:
1. mount a live-cd system from esxi control interface
1-1. setup guest booting option from web configuration interface:
check "force entering BIOS setting after next booting process" option
1-2. start guest virtual machine with live-cd iso file from host
2. umount any lvm directory
use df -h to locate correct path of lvm directories
like /dev/mapper/...
if facing a busy device issue, use umount -f
3. xfs_repair /lvm_directory
