find path/to/dir -user fred -exec chown barney:barneygroup '{}' \;

# Caveats:
# 1. Not only will this change the files under the specified directory,
# but it will change the directory itself, if the ownership matches.
# 2. Changing files owned by root can hose your system.

The symptoms are that none of the network interfaces are created, and running ifup complains with ifup: failed to open statefile /var/run/network/ifstate: No such file or directory. Manually creating the directory /var/run/network fixes this problem temporarily, allowing ifup to work.

The root cause of this is a change in the ifupdown package. In previous versions, /etc/init.d/loopback created the /var/run/network directory. In the new version, this action has been reassigned to /lib/udev/rules.d/85-ifupdown.rules. Because udev is disabled within OpenVZ VEs, /lib/udev/rules.d/85-ifupdown.rules was never run, and the /var/run/network directory never created.

We’ve fixed this by modifying /etc/init.d/networking and adding a line [ -d /var/run/network ] || mkdir /var/run/network immediately on line 53 immediately after start).

Unable to open pty: No such file or directory

Here’s the Fix:

vzctl exec VEID /sbin/MAKEDEV pty
vzctl exec VEID /sbin/MAKEDEV tty
vzctl enter VEID

To Fix this issue permanently:

1. Edit the file /etc/rc.sysinit of the VPS server

2. Comment the line
#/sbin/start_udev

3. Add the following lines after /sbin/start_udev:

/sbin/MAKEDEV tty
/sbin/MAKEDEV pty

4. Reboot your VPS
vzctl restart VEID

Ubuntu
vzctl exec VEID update-rc.d -f udev remove
