Microsoft has a free hypervisor offering called Hyper-V Server 2012 R2. Hyper-V Server 2012 R2 is fully equal to the Hyper-V role in Windows Server 2012. The only item not available in the free edition is the free usage rights for virtual machines running on a host installed with Hyper-V. Each virtual machine instance running on free Hyper-V Server 2012 R2 needs to be licensed.
Hyper-V Server 2012 R2 comes as a core installation. This means there is no graphical userinterface available to perform management. Especially connecting to the console of the virtual machine can be a challenge. Hyper-V Manager does not run on the Hyper-V Server itself. Adminstrators needs access to another Windows Server 2012 or Windows 8 with Remote Server Administration Tools (RSAT) installed to be able to access the console of VM’s.
Veeam to the rescue. The company released a free virtual appliance which is a RDP proxy. The appliance runs CentOS and installs on a Hyper-V host. The appliance can connect to virtual machines using VMconnect. VMconnect is a modified RDP for connection to consoles of virtual machines. VMconnect is able to connect even when the virtual machine does not have an IP-address.
