Re: A light VM for testing Xen.

[Jason Long <hack3rcon@xxxxxxxxx>]

Thank you.
I'm using Lubuntu:

$ uname -a
Linux Xen 5.8.0-25-generic #26-Ubuntu SMP Thu Oct 15 10:30:38 UTC 2020 x86_64 
x86_64 x86_64 GNU/Linux

And:

$ cat /etc/fstab 
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system>             <mount point>  <type>  <options>  <dump>  <pass>
UUID=4d7a5a50-9288-424d-a383-2f6888b908a1 /              ext4    defaults   0 1


Anything wrong?

Searching for GRUB installation directory ... found: /boot/grub
Cannot determine root device.  Assuming /dev/hda1
This error is probably caused by an invalid /etc/fstab


Can you describe your environment?
