i am having a hard time getting all the packages to install in my windows 7 desktop. can this be run from a linux server?

Yes, you can run the script from Linux server

The following instructions work for me

1. install python 3.6
$ sudo yum -y install python36u python36u-pip

2. install pyvmoni and other packages
$sudo python3.6 -m pip install pyvmomi
$sudo python3.6 -m pip install crypto
$sudo python3.6 -m pip install pyopenssl

3. download ESXi Compatibility Checker and run
$python3.6 ./compchecker.py -s <host> -u <username>

Thanks!

This tool has worked well for 32 hosts, but did not for two.
Server`1, version 5.5.0, build 3116895, ProLiant DL380p Gen8
Server2, version 5.5.0, build 3116895, ProLiant DL380p Gen8

What I am getting it the following error:
> collecting host information...
Please wait, this may take few minutes depending on the number of ESXi hosts...

Thank You for any help you can give me,

HI Todd,

It seems that pyvmomi fails to read Host.config information of the specific hosts. Can you access the host via MOB, the managed object browser? (https://<your-host-name>/mob) And browse the host config (Data Object Type: HostConfigInfo) to see it's accssible?
Thanks,
Heejeong

Managed Object Type: ManagedObjectReference:ServiceInstance
Managed Object ID: ServiceInstance

Properties

NAME TYPE VALUE
capability Capability capability
content ServiceContent content
serverClock dateTime "2018-07-11T12:19:18.264838Z"

Methods

RETURN TYPE NAME
dateTime CurrentTime
HostVMotionCompatibility[] QueryVMotionCompatibility
ServiceContent RetrieveServiceContent
ProductComponentInfo[] RetrieveProductComponents
Event[] ValidateMigration

I can access the MOB web page. What I do not see data object type: HostConfigInfo.

Hi Todd,

You will need to navigate the MOB tree to search the specific hosts and their hostconfig information. Do you have all permissions for the hosts?
Can you check the health status of the hosts?
Thanks,
Heejeong

is it possible to stuff this all into a photon machine and run it as an applaince?

I will investigate and get back to you. Thanks!
