Products

• VMware Cloud Director

Issue/Introduction

• When attempting to add a hard disk to a Cloud Director virtual machine, there is an error of the form:    Index: 0, Size: 0 
• When we try to add the second NIC to the VM, the below error is encountered:

[xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx ] Index 0 out of bounds for length 0

• The /opt/vmware/vcloud-director/logs/vcloud-container-debug.log file shows entries similar to:

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.rangeCheck(ArrayList.java:659)
at java.util.ArrayList.get(ArrayList.java:435)
at com.vmware.ssdc.backend.dao.impl.VAppVirtualMachineDaoImpl.getStorageContainerValRefForVappVm(VAppVirtualMachineDaoImpl.java:127)

 

Environment

VMware Cloud Director for Service Provider 10.x

Cause

This can be caused by missing "dstore_moref" values in the Cloud Director database's "vm" table.
Issue can also be caused when value for "dstore_moref" is present in "vm" table, however virtual machine resides on another datastore in vCenter.
