Hi,
Invoke-RestMethod or Invoke-WebRequest uses by default TLS 1.0. This protocal is outdated and would be not accepted by the most Webservers anymore.
Usually this results in the following error message:
The underlying connection was closed: An unexpected error occurred on a receive.

Hi,
the VMware Workstation does not provide a program or script to generate a new pair of key and selfsigned certificate.
If’ve written a batch file which builds a new one. The scripts assumes that the Workstation is installed in the default folder C:\Program Files (x86)\VMware\VMware Workstation and uses the openssl command delivered with the program.
Adjust the Countryname, State, etc. to your own needs. Config is based on the VMware Docs.

Hi,
VirtualBox offers a very powerful command inferface: vboxmanage. With vboxmanage you can create new virtual machine, add and modify harddisk and much more. All the things you could do in the GUI, and a lot more are also possible at command line. In this post I will create, modify, control and delete a complete virtual machine.
At the bottom of the post the whole script can be downloaded.
I used a debian linux system for my tests. To install the latest VirtualBox version use the following commands:
echo "deb http://download.virtualbox.org/virtualbox/debian wheezy contrib non-free" >> /etc/apt/sources.list # Add Oracle Keyring wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | apt-key add - # Update repositories apt-get update # Install latest virtualbox version apt-get -y install virtualbox-4.3 # Installing the Extentionpack for USB2 and RDP support wget http://download.virtualbox.org/virtualbox/4.3.6/Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack
