Simulator deployment fix for vCenter 6.5

SeanHatfield — Wed, 04 Jun 2025 15:04:07 GMT

When you deploy the ONTAP 9.1 simulator OVA to a vCenter 6.5 environment via the vCenter web client, you will see this error:

OVF package with compressed disks is currently not supported for OVF import.

This is a known issue found in the vCenter 6.5 release notes:

http://pubs.vmware.com/Release_Notes/en/vsphere/65/vsphere-esxi-vcenter-server-65-release-notes.html

The workaround is to repackage the OVA without compressing the disks. This is a one-liner with ovftool:

ovftool vsim-esx-DOT9.1-cm.ova vsim-esx-DOT9.1-cm-fixed.ova

This fixed version should deploy without the compressed disks error.

You can get ovftool from vmware as a standalone install here:

https://my.vmware.com/group/vmware/details?downloadGroup=OVFTOOL420&productId=491

Or you can use the one bundled with VMware Fusion or VMware Workstation.

/Applications/VMware Fusion.app/Contents/Library/VMware OVF Tool/ovftool

C:\Program Files (x86)\VMware\VMware Workstation\OVFTool\ovftool.exe

This doesn't seem to be enough to deploy the Simulator.

After I managed to decompress the disks using the ovf tool, then I get an error that the disk size is incorrect (larger than requested)

I managed to update the OVF and get it to deploy, but when I try booting up, it cannot find the disks...

Which version of the simulator? and which version of vCenter?

Ok, so this is for Version 9.3 and ESXi 6.5 (not vCenter)

The behavior I'm seeing more specifically is:

I can uncompress the disks no problem. When I try to deploy the OVA I get the following error.

Error uploading file <path-to-ovf.vmdk> to server. Capacity of uploaded disk is larger than requested

as per this:

https://kb.vmware.com/s/article/2094607

I changed the following:

Navigate to the location of the OVF file
Open the OVF file using the text editor, and locate these tags:

<DiskSection> </DiskSection>
Within this section, change the ovf:capacity="XXXXX" to the correct size of the vmdk(s)

and after playing with some numbers, I managed to get it to deploy, BUT:

After the deploy is successfull the sim won't boot up. I just get the DHCP client trying to find an IP to PXE boot from on all 4 network adapters and then just says missing OS.

It may have built it with a newer vmx version. I think vmx10 is that last one that works without intervention. It's also possible the disks are attached in the wrong sequence. The bootable disk is the ~2gb disk on IDE0:0.
