I recently deployed a new Microsoft Windows Server 2012 VM that runs a legacy application that looks to a dongle attached to the parallel port.
I had to install an additional PCI Express Parallel Port Card and enable the VT-D technology on the host system, configure the card in "PCI pass-through" mode in order to add it to a VM.
The customer is already using Veeam B&R for the rest of the VMs and needs to use it to backup the new VM as well. Since snapshots are not supported with PCI vSphere Direct Path I/O devices, I am thinking about putting the new VM in a separate job and using a PowerCLI script which will shutdown the VM before starting the corresponding backup job for this VM and power it back on after the backup job completes.
Would anyone see anything wrong with this or suggest another solution to accomplish this task ?
Any help/information will be greatly appreciated.
Thanks and Regards,
