Hi,

 

I have been looking over the requorements for running a VM in UNRAID 6 and have some inforamtion that confuses me.

 

In the FAQ the (extract below) it is clear that the CPU must support VT-x. The second section talks about assigning PCI devices, and in that case the CPU must also support VT-d. In a video on youtube by Jon Panozzo it is said that VT-d is required outright.

 

The system i have currently mocked up only supports VT-x, i am using onbaord graphics for the display and a raid card to handle HDD pass through. In this scenario is VT-x enough (i3 4170)

 

"To create virtual machines on unRAID, you will need HVM hardware support (Intel VT-x or AMD-V). To assign host-based PCI devices to those VMs, your hardware must also support IOMMU (Intel VT-d or AMD-Vi)."

 

Thanks for any help.

Without VT-d support you will have to use VNC or RDP (or an equivalent) from another system to display the graphics from the VM.

 

You will also not be able to pass through the RAID card.  However you should be able to pass through the disks attached to it (although I think they have to be below 2TB in size for this to work) but you will have to do some hand editing of the VM XML configuration file as the unRAID VM manager does not handle passing through physical drives at the GUI level.  Most people do not pass through the actual physical hard disks, but use virtual disks (which at the unRAID level are files holding the disk image).  Not quite sure what your needs are in this area.

Thanks for the quick reply.

 

Based on that i think an i3 will be fine. Im just going to map a network drive in the Windows VM so accessing the hard drives directly wont be an issue (especially since it wont be able to read the file system anyway.).

is vt-d required if I want to attach a USB blu-ray player to a VM?

You will not be able to use it fully unless you pass through a USB controller also I'm afraid.

What do you want to use the blu-ray for?

I use it as my device to make backups of my movie collection.  It only makes sense to me to attach it to a VM running on my Unraid box.  So anytime I can just RDP into the virtual machine, plunk in a new disk, and make a backup.

You can either use my MakeMKV docker and/or the handbrake docker for backing up movies. That works like a charm with the usb player connected to unraid 

That is what I am planning on doing, but if I can't connect my USB blu-ray burner without vt-d, I'm going to have a problem.

 

So that is why I am looking to find out if I can pass through a usb device without vt-d or do I need it?

You do not need vt-d to use the blu-ray drive in my MakeMKV docker.
