Virtual Machine Disappeared on vCenter Inventory

Just googled this issue, some of people got similar problem, following was my problem and solution, hope it's useful for you.

Virtual machine maybe lost on vCenter Server inventory for some reason, it's also disappeared on ESXi inventory when you connect to the individual host directly. You are able to find the VM process by esxcli vm process list, but not able to get it by vim-cmd vmsvc/getallvms.

If you try load the VM manually by commeand vim-cmd vmsvc/reload [vmid], it back you error:
(vim.fault.NotFound) {
dynamicType = <unset>,
faultCause = (vmodl.MethodFault) null,
msg = "Unable to find a VM corresponding to "vmid"",
}

You can also find the VM process by esxtop command.

My solution was remove the ESXi host from vCenter Server, then restart management services, and then browse the VM folder, add the VM back to inventory, then join the host back to vCenter Server.

Connect-NsxtServer shows "Unable to connect to the remote server"

When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false

Setup Terraform and Ansible for Windows provisionon CentOS

Provisioning Windows machines with Terraform is easy. Configuring Windows machines with Ansible is also not complex. However, it's a little bit challenging to combine them. The following steps are some ideas about handling a Windows machine from provisioning to post configuration without modifying the winrm configuration on the guest operating system.

How to List All Users in Terraform Cloud

Terraform has a rich API. However, the API documentation does not mention how to list all users. We can leverage the organization membership API and the PowerShell command  Invoke-RestMethod  to get a user list. 1. Create an organization token in Terraform Cloud. 2. Create the token variable ( $Token ) in PowerShell. $Token = "abcde" 3. Create the API parameters variable in PowerShell. $params = @{ Uri = "https://app.terraform.io/api/v2/organizations/ZHENGWU/organization-memberships?page%5Bsize%5D=100" Authentication = "Bearer" Token = $Token ContentType = "application/vnd.api+json" } Note: You need to replace ZHENGWU with your own organization name. And I used 100 at the end of the URI to retrieve the first 100 users. It can be any number.  4. Retrieve the API return and list the user's email address. $Test = Invoke-RestMethod @params $Test.data.attributes.email
