lxc-start fails on 'lxc-create -t ubuntu-cloud' container

[Scott Moser]

$ name=precise-cloud-amd64-source

$ sudo lxc-create -t ubuntu-cloud -n $name -- \
  --release=precise --arch=amd64 \
  --tarball "$cached/$tarball"
$ sudo lxc-start -n precise-cloud-amd64-source
lxc-start: No such file or directory - failed to mount a new instance of '/dev/pts'
lxc-start: failed to setup the new pts instance
lxc-start: failed to setup the container
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'precise-cloud-amd64-source'

Previously, I thought I coudl fix the situation with the following, but that seems not to have worked.

$ rootd=/var/lib/lxc/$name/rootfs
$ sudo cp -a /dev/{console,urandom,random,tty[1234]} $rootd/dev
$ sudo mkdir $rootd/dev/pts

Thanks for reporting this bug. This is due to the same problem as bug 1060404. The workaround is the same as the solution - add a devtmpfs entry to /var/lib/lxc/$name/fstab.

The solution is queued for acceptance to precise-proposed.
