During the deployment of OVA or OVF appliance I have faced an issue which is:
Failed to deploy VM: postNFCData failed: Capacity of an uploaded disk is larger than requested
This issue occurs when an incorrect ovf capacity size is specified in the OVF file that is being deployed.
To resolve this issue, I have increased the disk size in the OVF file to match the actual size of the vmdk in the OVF, to increase disk size in OVF file follow listed steps.
- Navigate to the location of the OVF file, also if you have OVA file just unzip OVA file and start to edit the OVF file after that.
- Open the OVF file using the text editor, and locate these tags to check the OVF disk actual size.
<DiskSection> </DiskSection>
Before correction ovf capacity 
After correction ovf capacity 
Note: Size format is in MB.
- Save and close the file.
- Deploy the OVF again.
Thanks.
