CPU limitation using .ova

[ozz_cz]

Hi guys,

recently I came across strange thing - while deploying .ova VM I cannot select more than 8 CPUs

I DO use free license so this is acceptable, but then a customer of mine complaints it does not allow him to use more cores even having licensed ESXi.

Other machines are using up to 12cores without issues there.

While I create VM manually and install the system (based on RHEL6-64bit) using .iso I can select up to 24 cores - limited by the license naturally.

Trying to dig into the .ova I found this portion in .ovf

So is THIS the limitation? 1 virtual CPU(s) / WirtualQuantity?

I do not think so... 😞

Regards,

Ondrej

Based in your appliance .ovf file, you're using virtual hardware version 7 (vmx-07), and the virtual hardware version 7 is limited to 8 vCPU, see the following VMware KB article to configuration limits to each hardware version: Hardware features available with virtual machine compatibility settings (2051652) | VMware KB

If you want more than 8 vCPU, you will need to upgrade the virtual hardware version, but if that OVA is a vendor appliance, check with the vendor if they will support that deployment after the virtual hardware upgrade, and always take a snapshot before the upgrade, just in case you need to rollback the change.
