Unable to create/deploy VM in one vApp - NullPointerException

-


Symptoms:

java.lang.NullPointerException
  • Unable to deploy a VM in only one vApp 
  • It didn't matter which template I use.
  • The same template works fine in another vApp in the same OrgVDC 

The error NullPointerException is quite generic with vCloud director and this is mostly due to a stale/invalid entry in the vCloud director database. 

Analysis : 

The vCloud-container-debug.log failed with the below

java.lang.NullPointerException
             at com.vmware.vcloud.common.validate.impl.VmLimitsValidatorImpl.validateVmDisks(VmLimitsValidatorImpl.java:159)



After checking a bit more in the logs just above the error, I found that vCD was unable to query a VM storage information. 



In my case, it was 'IncomeOnline-Rock_DeleteOn' with moref  vm-3055.  The vm did not exist in my vCenter and was part of the same vApp in vCD where I have deployment (VM creation) issue. 

Fix  : 

Deleted the VM named 'IncomeOnline-Rock_DeleteOn' from vCD and this resolved the deployment issue. 


Hope this helps :)

vCloud director 9.7 appliance deployment step by step guide

-
Image
With the new vCloud director releasing and making it full appliance with embedded vpostgres, I though I will put up a post with the complete installation guide. There have been some challenges in the getting the deployment successful.

Prerequisite :
Reverse DNS proxy must be configured for the eth0 ipaddress. This is to get the correct hostname for the appliance. The NFS share is setup for the VCD transfer directory.It is recommended to have the eth0 and eth1 in different subnets. eth0 is for the vcd cell and eth1 is for the vPostgres .The reason for the having 2 subnets is to avoid duplicate entries in the route table. 
Installing vCloud director step by step guide : 






I should ideally be using different submets as per the VMware documentation but since I do not have a different portgroup setup, I am going with the same subnet. As mentioned in the prereq section, the reason for the having 2 subnets is to avoid duplicate entries in the route table


Here we come to the main section. The NTP …

How to Install and Uninstall Guest agent for vRA Windows machines

Connect to the vRA appliance using the IP or hostname 




Choose the appropriate setup for your Windows server 


Extract the files to C:\VRMGuestAgent\ . In my case, I have already extracted it. 


Before you install the guest agent download and install the IAAS manager server certificate into the windows machine 



Save the file as Cert.cer 



Install the Cert into the Local machine and Trusted root store



Rename the cert.cer to cert.pem and move it to folder C:\VRMGuestAgent\


Now, copy the certificate file into the vRMGuestAgent Extracted folder 


Open the command prompt as admin and navigate to C:\VRMGuestAgent. In this case 192.168.2.15 is my Manager server . The default port is 443. 


You will see the Guest agent service in the services list. Manually start the service. 




Your windows guest agent is installed :)

Unable to change Provider VDC virtual hardware support beyond version 10

-
Image
My environment:

vCloud Director 9.1.0.3 and ESXi 6.5.0.

 This could happen regardless of what vCloud director and ESXi version you are on.




Provider VDC config: 


ESXi Version : 



So ideally I should be able to see the hardware version 13 in the vCloud director but I see only till version 10


Why does this happen : 

It’s most likely a user error depending on how vCenter is set up and what vCenter has reported to VCD as far as available HW versions

How to fix ? 

 From vCenter FLEX UI, go to Datacenter, right click and select 'Edit Default VM Compatibility' and there select 'ESX 6.5 and later' (This config depends on your environment)
Then go to the cluster and right click and select 'Edit Default VM Compatibility' and there the value selected would be 'Use datacenter setting and host version'. This setting would take it from datacenter setting done above.

From the vCloud director , perform and refresh of the vCenter and try to create the Provider VDC and check the…
