7. Keeping Your System Up To Date¶

This chapter explains the ways to keep your hardware node up to date. The components you need to take care of are the following:

• Virtuozzo software,
• virtual machines and containers hosted on the server.

To apply major updates that usually include new kernel versions, follow the instructions below:

1. Stop all running virtual environments on the server that is to be updated, or migrate them to other Virtuozzo 7 servers to avoid their downtime.

2. Update the server as described in Updating All Components.

3. Restart the server to update the kernel.

4. Start the virtual environments or migrate them back to the updated server, depending on what you did in step 1.

5. Perform steps 1-4 for other Virtuozzo servers that need to be updated.

   Note

   Steps 1-4 can be also performed via Virtuozzo Automator.

6. If you use Virtuozzo Automator:

   1. Update the container va-mn either via VA (see Updating System software) or by running the following command on the server:

      # prlctl exec va-mn yum update
      

   2. Restart the container to apply the update:

      # prlctl restart va-mn
      

7. If you use Virtuozzo Storage management panel:

   1. Update the container vstorage-ui either via the management panel (see Managing Virtuozzo Storage Updates) or by running the following command on the server:

      # prlctl exec vstorage-ui yum update
      

   2. Restart the container to apply the update.

      # prlctl restart vstorage-ui
