In XCP-ng, the XenAPI missing container occurs when it cannot find or access a particular virtual machine (VM), host, or container. Bobcares, as a part of our Virtualizor Support offers solutions to every query that comes our way.

XenAPI Missing Container in XCP-ng

A XenAPI missing container error occurs when a certain VM, host, or container will not be available for the XenServer/XCP-ng administration interface.

Here are a few typical situations when this mistake might arise and how to fix it:

1. VM or Container Does Not Exist:

If we attempt to access a virtual machine (VM) or container that doesn’t exist on the XCP-ng host, this error can appear. Make that the VM is currently running on the host and that we have the right name or identification for it.

2. Corrupted VM Metadata:

Sometimes a VM can appear to be “missing” in the administration interface due to problems with its metadata. We can try to re-import the VM from its storage or try to update the information.

3. Network or Connectivity Problems:

It’s possible that the management tool won’t be able to see the virtual machines or containers if it can’t connect to the XCP-ng host because of a network problem or misconfiguration. Make sure the host is available for the control station and that the network setup is correct.

4. VM Has Been Removed or Deleted:

A deleted or removed virtual machine won’t show up in the administration interface. Make sure the VM wasn’t deleted accidentally by checking twice.

We must also verify that the VM or container is present and active on the host. By using SSH to connect to the host or other command-line tools for managing virtualization, we can accomplish this. Check for the connectivity and networking between the management interface (like XenCenter) and the XCP-ng host. Also, make sure we can communicate with the host. We also need to refresh the VM’s metadata or try to re-import the VM if we think there is a problem with it.
