worked for me with a beta release of ubuntu 14.04. used part of the 12.04 howto as a guidline.
I debootstrapped trusty on another ubuntu box before copying it to a CentOS HN. the debootstrap-script on CentOS didn't work for 14.04
please append/edit if you feel i missed something
howto:
debootstrap --arch amd64 trusty /vz/private/2111 ftp://ftp.ubuntu.com/ubuntu
vzctl set 2111 --applyconfig basic --save
vzctl set 2111 --ostemplate ubuntu-12.04-x86_64 --save
vzctl set 2111 --ipadd x.x.x.x --name trusty --hostname trusty.test.intern --save
vzctl start 2111
apt-get update
apt-get install vim
apt-get remove ntpdate
add to the start of init script /etc/init.d/ondemad
[ ! -f /etc/init/lxc-android-config.conf ] || exit 0
[ -d /proc/vz ] && [ ! -d /proc/bc ] && exit 0
or simply "exit 0"
fix rsyslog
sed -i -e 's/^\$ModLoad imklog/#\$ModLoad imklog/g' /etc/rsyslog.conf
disable sync
sed -i -e 's@\(space:\)\(/var/log/\)@\1-\2@' /etc/rsyslog.d/*.conf
delete unneeded init-jobs
rm -f /etc/init/console* /etc/init/tty*
comment the following lines in /etc/init/rc.conf
console output
env INIT_VERBOSE
change /etc/apt/sources.list to something like
deb http://archive.ubuntu.com/ubuntu trusty main universe multiverse
deb http://archive.ubuntu.com/ubuntu trusty-security main universe multiverse
