[Video guide *** How to connect virt-manager to unRAID to help manage your VMs **]

Anyone get this working with a more recent version of virt-manager? With mint 20 there is not method drop down (~7:35 in video) to pick TCP.

 

Nevermind, I solved this. Custom "URIs" are created for this behind the scenes. I created a connection on my old rig and copied the text.

 

Example: qemu+tcp://[email protected]/system

Thank you!  This was my problem.  This solved it for me also.

[[Plugin] Linuxserver.io - Unraid Nvidia]

Sorry if this has been answered recently, but searching hasn't given me anything too helpful.  I have been using this plugin with no problem with my GTX 1080s, however I have a second Unraid build that I'd like to use an Nvidia Tesla K80 that I picked up for some machine learning use cases.  Since this plugin did not seem to have an option/driver for Tesla GPUs from what I could see, I was wondering if there is a manual process to install the Tesla driver after installing the plugin?

 

I've tried passing through the GPU to a Ubuntu VM however I'm having other driver install issues there (probably user error on my part) so I was just wondering if it was feasible to do in Unraid with any manual steps.  Basically I just want to run some stuff in Docker containers, whether that be direct in Unraid's Docker or a VM with PCIe pass through.

 

Anyone got any experience getting a Tesla to work in either approach in Unraid?

 

EDIT: Just an update, the 'regular' NVidia drivers worked.  My problem was that I was using an old motherboard/CPU that did not support IOMMU for PCIE passthrough.  A new motherboard and CPU solved this.

Apologies if this has already been answered, but I searched and came up blank here and when Googling it.

 

I get the following error in the log when trying to create a regular RDP connection to a new Windows 10 box.

guacd[948]: ERROR:	Error connecting to RDP server

I have not changed or disabled any RDP parameters on the Windows 10 box aside from simply enabling Remote Desktop itself.  The connection is set up to use NLA (Win 10 default from my reading) and Ignore Server Certificate.

 

Any thoughts?  I can connect fine via Mac RDP and Windows RDP clients to this box.

[Hardware recommendations for unRAID servers with VM's]

StarTech.com 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter w/ 2 Dedicated 5Gbps Channels

Chipset: Renesas/NEC - µPD720202

Findings: Purchased this because it had 4 individual USB controllers on the board thinking the extra price would allow for more flexibility with my VMs.  Requires SATA/Molex power, works fine when booting native to Windows 10.  It is recognized in Unraid under Settings -> Hardware however when passing through the PCIE card to a VM, while the card is detected, it always has an error with Code=10.  This is with the standard Windows drivers and also with the drivers from the manufacturer's website.  There are other posts online with the same result (Code=10 error in Device Manager) but not promising workarounds.  I suspect this is something at the Linux level as when I do not pass through the PCIE card and hook up USB devices directly to the card, they also are not recognized by Unraid.  I give up on this card.

Piling on to this thread.  Spent $80 on this card thinking it would work and it recognizes and then just Code=10s in Device Manager :(

[Encryption and auto-start]

So I've done a semi-equivalent of what you guys are doing here except I'm using scp to pull my key down from an AWS micro instance (might switch this to a Pi Zero on premise though - thoughts on drawbacks/benefits here?) that is always on.  I like the examples where I can delete the key after the disks are mounted which is why I stumbled onto this thread.

 

One idea I had was to somehow enhance the scp/ftp/whatever protocol process to somehow fire off a process on the remote machine that holds the key to send maybe an SMS text to my phone where I respond with a PIN code to allow the key transmission to take place.  Are there any inherent flaws with pursuing this?  One concern I have is there will obviously be a lag between when the ssh command between Unraid go script and the key and be transmitted back and then it's a race condition?  Is there a shell command on the Unraid side that I can call again to mount the drives once the file has been received?
