Andrewch Posted February 12, 2016 Share Posted February 12, 2016 Hi all, I'm trying to get a Windows VM running via unraid. I have got it up and running (with no network access or sound) through the VNC remote via the unraid gui. I'm running an intel G540 CPU therefore no VT-d only VT-x. I have enabled the virtualisation tech in the bios and the HVM is tagged as "Enabled" in the unraid gui info. No IOMMU devices show up - because no VT-d (I think) What I want to do run the VM on a separate monitor not via the VNC remote but rather via a HDMI/DVI/VGA cable from the unraid tower. Correct me if I'm wrong but connecting directly to the motherboard outputs is not supported, right? So I installed an old Nvidia PCI graphiocs card but cannot seem to select that when configuring the VM in unraid (because no VT-d?). I run the system headless so I have no need for a monitor for unraid. The BIOS is set to use on onboard as the primary and I can see unraid when I connect a monitor to the onboard ports. So basically, will my system allow me to connect a monitor to the unraid tower for it to display the VM or do I need to buy a processor that supports VT-d? I feel like I'm 80% there on understanding enough to get this thing going but cant match up the final dots. Thanks Quote Link to comment
itimpi Posted February 12, 2016 Share Posted February 12, 2016 No. Without VT-d support you will not be able to use a monitor connected directly to the unRAID server. It is the VT-d feature that support hardware pass-through so without that you can only connect into the monitor remotely. Note that it is not just the processor that needs to support VT-d, it is also the motherboard+BIOS. Quote Link to comment
johnodon Posted February 12, 2016 Share Posted February 12, 2016 Speaking specifically about Intel, if your MB and CPU both support... Only VT-x - you can create/run VMs but will only be able to connect to a virtual display (VNC, RDP, etc.) Both VT-x and VT-d - you can create/run VMs and also passthrough a dedicated GPU to a VM and connect a monitor to that GPU's output port (VGA, HDMI, DVI, etc.) John Quote Link to comment
