Windows Vms outright stopped working for me (Corrupted bootup)

[Squazz]

For the past 3 years, I've been daily driving a Windows VM (see link for topic around my setup)

 

I've had some problems here and there, but this week everything just went heywire.

I've started to get currupted boots, every, single, time.

After tinkering with it for the past week, i've tried setting up a bunch of new VMs today. Fethcing the latest ISO for Windows, and basing my VMs on that.

After install all of the updates, and rebooting, the problems starts. Sometimes the system just halst after trying to start up windows for half and hour. Other times it goes strait to the blue screen, telling me that bootup is corrupted, and needs to be repaired (which I'm never able to do).

 

 

I'm trying to set up the machine with 

CPU Mode: Host passthrough

10 logical CPUs pinned (and isolated)

Initial Memory: 30720

Max Memory: 30720

i440fx-5.1

OVMF

USB 2.0

Primary vDisk Location: auto: /mnt/user/domains/Windows 10/vdisk1.img

Primary vDisk Size: 110Gb

Primary vDisk Type: Raw

Primary vDisk Bus: VirtIO

Passing through:

- 1070ti

- 1070it soundcard

- onboard soundcard

- Stubbed USB 3.0 controller: AMD Family 17h (Models 00h-0fh) USB 3.0 Host Controller | USB controller (30:00.3)

 

The share "Domains" is set to "Prefer : Cache"

 

My Cache pool is a single 500Gb Sata SSD: Samsung_SSD_860_EVO_500GB_S4XBNF1MA02769A - 500 GB (sdb)

 

unRaid version: 6.9.2

I'm running the latest BIOS version for my motherboard

 

My Hardware

CPU: Ryzen 7 1700 (65W)
Motherboard: MSI MS-7A33 motherboard
Ram: 16GB (2x 8GB 2400Mhz) + 32Gb (2x 16GB 2400Mhz)

Raid drive: LSI 9201-8i

GPU: 1070ti

 

What can I provide of information to help you help me? I'm kinda stuck, I don't know what to do from here.

Right now, I'm unable to use unRaid to host Windows VMs

For GPU pass thru on Windoze I use Q35-5.1 as Machine Type and a BIOS set to SeaBios. Know this to be a recommendation of SpaceInvader1 and it works well for my VM's. Suggest that you give it a try 🙂

Interresting, can you find a concrete place where this is recommended?

As far as I know it's only recommended for Linux & MacOS?

As a first step of troubleshooting without having seen any details:

Have you tried removing all passed-through devices from the VM and tested if it starts up correctly?

I run my Windows10 VM's this way, on my 1050Ti, and it works flawlessly; up to you whether you wish to try it

Yup, tried that. When first the VM gets in the "wont boot" state, nothing can save it.

Oh, I'm gonna try it out

I was just wondering why the official recommendations said not to use that setup, if that is the most stable setup
