 In case of all VMs have vmware tools installed, use below command to list all IP address assigned for VM inside a ESXi server for i in `vim-cmd vmsvc/getallvms | grep -v Vmid | awk '{print $1}'`; do vim-cmd vmsvc/get.guest $i | grep -i 'ipaddress = "'; done

 Azure VMware Solution(AVS) provides a vCenter server with minimum 3 node ESXi hosts while provision.  But the issue is that AVS will be created with only private cloud networks. For accessing we need to create a windows jump host .For this follow below step 1.Create AVS. 2.Create a resource "virtual network" on the same region of AVS. 3.Create a resource "virtual network gateway" with "express route" as type. 3.create a express route key  request on AVS.       AVS->Connectivity:       Now copy express ID and key. 4.Go to VPN gateway ->Connections->Add connection      check "redeem authentication" and provide "express key/ID" 5.Now create a windows jump host server on the above create vNet.
