Cause

• This is expected behavior and occurs when there is a serial port attached to the original virtual machine / OVF for vCenter Server and ESXi
• On vCloud Director 10.4 it was detected an issue while the script expects OVF with serialPort entry to have direction and serviceURI
  • Issue is fixed on 10.5.1.22694873

Resolution

• To resolve the issue, remove the serial port from the original virtual machine and export to a new OVF.

 

If the original virtual machine is not available, edit the OVF file and remove the Serial Port Section.

 

To remove the Serial Port Section:

1. Navigate to the location of the OVF template.
2. Create a backup of the templatename.ovf and templatename.mf files.
3. Open the templatename.ovf file using a text editor.
4. Locate and remove the Serial Port section and save the templatename.ovf file. The Serial Port section looks similar to:
   
   

   <Item ovf:required="false">
   <rasd:AutomaticAllocation>true</rasd:AutomaticAllocation>
   <rasd:ElementName>Serial port 1</rasd:ElementName>
   <rasd:InstanceID>12</rasd:InstanceID>
   <rasd:ResourceSubType>vmware.serialport.device</rasd:ResourceSubType>
   <rasd:ResourceType>21</rasd:ResourceType>
   <vmw:Config ovf:required="false" vmw:key="yieldOnPoll" vmw:value="true" />
   </Item>

    
5. Open the templatename.mf file using a text editor.
6. Locate the row that contains the SHA1 hash of templatename.ovf and remove this line.
7. Save the templatename.mf file.
8. Redeploy the virtual machine using the modified templatename.ovf.

 

• For VCD 10.4.X the configuration should be as bellow:

 

<Item>
<rasd:AutomaticAllocation>true</rasd:AutomaticAllocation>
<rasd:ElementName>Serial port 1</rasd:ElementName>
<rasd:InstanceID>12</rasd:InstanceID>
<rasd:ResourceSubType>vmware.serialport.uri</rasd:ResourceSubType>
<rasd:ResourceType>21</rasd:ResourceType>
<vmw:Config ovf:required="false" vmw:key="backing.direction" vmw:value="server"/>
<vmw:Config ovf:required="false" vmw:key="backing.serviceURI" vmw:value="127.0.0.1"/>
<vmw:Config ovf:required="false" vmw:key="yieldOnPoll" vmw:value="true"/>
</Item>
