I am having the same problem concerning /dev/root on Ubuntu 14.04LTS on my VPS. It worked fine when I did a trial install in a VirtualBox machine under Windows.
Creating the symlink ( /dev/xvda in my case) helped. But when I rebooted, the problem came back..
Is there a way of creating the link so it persists across boots (or have it created in a startup file)?
SOLVED I put "ln -s /dev/xvda /dev/root" into /etc/rc.local before the "exit 0" statement.
My VPS system:
(Ubuntu 10.04 LTS, Kernel 3.4.2-linode44, Apache 2.2.14, MySQL 5.1.63, PHP 5.3.2, ISPConfig 188.8.131.52, Webmin, PureFTP & Quota, phpMyAdmin, postfix, dovecot, clamav, spamassassin, awstats, fail2ban, Jailkit, bind9, vlogger, webalizer)
