Resolution

In addition to using our native migration capability of a virtual environment from one hardware node to another, these machines can be moved manually.

1.  Before attempting this manual movement, we recommended that your environment have unique VE IDs across all of your servers.  By doing this, it will avoid any possible renaming of the VEs.  By using the Virtuozzo Cluster feature, it can take care of the automatic assignment of VE IDs.  However, if there are VEs have the same IDs, please change the ID prior to this manual move.

2.  Stop the VE and disable the offline management through our command line interface (CLI).  In the example below, the VE that will be migrated manually will be VE ID 101.  The Virtuozzo program is also assumed to be installed under the default directory (C:\VZ directory)



3.  Move the content of C:\vz\private\101 folder from the source node to the same place on secondary node.

   3.1. Check whether the migrated VE resides in an alternative location or it has additional drives which are on non-default folder VZROOT\private\VEID. The easiest way to check it is to run command "vzquota stat VEID" in Hardware Node CLI. In case if the VE is in different folder or has disks placed on different node's drives it is necessary to correct VE's conf file after the step 4. In order to change VE's private area location “VzPrivate=path_to_CT_private_dir" variable is to be corrected in the conf file. To define the correct location for additional drives of the VE it is required to modify corresponding "DRIVE_...=" variable in the conf file.

   3.2. The additional drives (efd-files) might be “shared”. In this case it is necessary to move such drives with the disk’s primary owner (the owner is the VE which exclusively uses the disk at this time). It is also recommended to migrate all VEs which use the shared disks to the same node.

   3.3. The migrated VE can have a vzcache template installed. "VzcacheTemplates=" variable in VE's conf file points to the fact the VE uses vzcache template. This template can be found in "C:\vz\Templates\__vzcache" folder of the HW node and needs copying to the target node.

4.  Move the file C:\vz\conf\101.conf

5.  Just after you moved the files, run the following command on DESTINATION node:

    

6.  If the VE you move is “bound” to specific network adapter, you should either “unbind” it by executing

  

   Or bind it to corresponding interface on the target node by executing

  

 where the string AA-BB-…-FF is just the MAC address of the required interface on the destination node.

7.  Once this is done, you may see that 101 is present on the destination node.  You can verify this by running

.

 You may also start the VE by running
