Success VM on Win 10 working after 14 iterations

[Swampy]

I just want to share a moment of Ah............................

I spent 4 days trying to find out why I couldn't start VM 10 pro with a video card. I had no problems headless loading. I had no problems loading Ubuntu.  I tried all suggestion I could find on this forum. Frustration was building. I finally copied the XML into notepad2 so I could see the code with more line available. What an advantage to actually see more lines.

 

Now I have been concentrating a lot of my time looking at the pass thru portion of the code. Keep in mind that I only have been reading code for 4 day (rube). I could not see much different different than the previous 13 iteration with exception of my passthru of USB and SCSI.

 

This last time I went going down thru the code from top to bottom I seen something. 

<cpu mode='host-passthrough'>

    <topology sockets='1' cores='2' threads='1'/>

  </cpu>

My CPU is threads='2'/> , once I corrected that I had instantaneous gratification. Graphics Card came to life when I hit start......Stress is gone for now, Still a lot of ground to cover.

I feel so much better. 

 

Hopefully this will help someone else.

So you were setting your VM up with 2 cores but the hyperthread of only one? Your CPU should show cores 0-7 in the edit window, so which were you selecting?

I have had issues with windows 10 too, my usb3 wont work in windows 10 neither will my onboard sound. Asus p9 X79 motherboard.

Ive always wondered what the correct way was to pass though hyperthreaded cores to VMs is.. not sure the GUI takes this into account as each thread is reported as a core to unraid (thats what the gui suggests anyway)

[Swampy]

Listen, I am new to this so I have been going thru lots of trial an error because nothing worked from the forum. All I know is I have a quad core dual thread processes. It does report as 8 cores with hyper thread from what I could tell. I can not select Hyper thread in the GUI and make it work. If I enter 2 for treads in the XML it works.

 

If some one wants me to try a limited amount of iteration to flush this out for other I'm willing to help so myself and others can benefit from it. Like I said, I don't know what to look for!

 

Attached is the functional XML and for the Host Pass thru shows 4 being passed thru I had to change threads to 2.

I just don't want to report a bunch of BS.

Oh, Something I did different this time is with the past iterations I used the last 4 of the 8 cores in the GUI. This One I selected the first 4.........So does this mean I had zero cores selected previously so it would never start in VM for Win 10 Pro ?

 

Thanks

 

[update] Today I could not get the VM to load. Yesterday was the first sign of life but was short lived. What totally confusing me is Ubuntu has zero issue in launching....... If I compare the XML there pretty close to being the same. Ubuntu works directly off the template but Win 10 is fussy.
