Failure to Start a Container

An attempt to start a Container fails.

Solution 1

If there is a message on the system console: parameters missing , and the list of missed parameters follows the message, set these parameters using the pctl set --save command (see Performing Initial Configuration for instructions). Try to start the Container once again.

Solution 2

If there is a message on the system console: IP address is already used , issue the cat /proc/vz/veinfo command. The information about the Container numeric identifier, Container class, number of Container's processes and Container IP address shall be displayed for each running Container. This shall also demonstrate that your Container is up, i.e. it must be running without any IP address assigned. Set its IP address using the command:

pctl set CT_ID --ipadd IP_addr --save

where CT_ID represents the Container numeric identifier and IP_addr represents an actual IP address.

Solution 3

Poor UBC parameters might prevent the Container from starting. Try to validate the Container configuration (see Validating Container Configuration ). See what configuration parameters have caused the error and set appropriate values using the pctl set --save command.

Solution 4

The Container might have used all its disk quota (either disk space or disk inodes). Check the Container disk quota (see the Managing Disk Quotas section and Chapter 4 for details) and increase the quota parameters if needed (see Setting Up Per-Container Disk Quota Parameters ).

Solution 5

Run the vzfsutil utility to make sure that the VZFS symlinks inside the Container work correctly. For example:

vzfsutil --call –t /vz/template /vz/private/< CT_ID >

The complete reference on the vzfsutil utility is provided in the Parallels Command Line Reference Guide .

Solution 6

The Container administrator might have inadvertently modified, replaced, or deleted any file that is part of an application or OS template, which has brought about the Container malfunction. In this case, restore the file(s) with the pctl recover command (see the Reinstalling Container section for details).

Solution 7

Restore the latest operable copy of the Container by means of the vzrestore utility (see the Managing virtual machine and Container Backups section for details).
