Hi wise ones,

could you please verify if the current HCI Bench Release is affected by CVE-2021-40438 (

As this CVE is rated as critical (Base Score 9 out of 10) it seems to be a good idea to offer an updated or fixed version.

Kind regards,

I have an issue with the reporting, including the PDF report that is created. I have 10 ESXi hosts, deploy 40 VMs over them all (4 VMs per host), it reports correctly that 40 VMs were used. When I use 80 VMs, then the report only shows 53 or 56 VMs, never the full 80. Any tips? I see the CPU usage is active for all 80 VMs, the reporting just doesn't show up right.

I've found that the more VMs you add to the test, the longer it takes them to show up in the monitoring dashboard. If you only have 12 or 24 VMs no problem, they appear almost right away. Once I get to 48 VMs, or 60 VMs, you have to make the test time 15 to 20 minutes minimum for them all to "check in". I think I'm good now, knowing I just need to give it more time.

Is there any plan to open source this project?

I am new to HCIbench. I am in the process of installing VDBench in a vSAN v7.0 environment.. I need detailed instructions (step-by-step) on how to complete the installation process. For instance:

1. what system should VDBench be installed on?
2.what directory should I install VDBench
3.where should Java be installed

If there is link I can point to, that would be awesome.

there's a user manual you can check out.

you dont need to care about anything of vdbench, hcibench allows you to use embedded fio or vdbench, vdbench installation will be taken care by hcibench, you just need to download the vdbench zip. java etc. is already installed.
