Hi all, linux noob alert (thought I'd get that in at the start)

 

I'm struggling with trying to get a SteamOS VM running using Seabios + Q35 because whenever I start it, I get the selection screen for the install but keyboard and mouse just don't work.  I get the same issue whetever OS I'm trying to use with Q35 (tried Ubuntu). FYI I'm also passing through the GPU.

I have a Windows 10 VM running perfectly with the same keyboard and mouse and same GPU passthrough but that uses Seabios + i440fx. I also tried creating a SteamOS VM using i440fx which does install but then hangs on first reboot and then crashes unraid

 

Has anyone seen this issue? I'd be grateful for any help on this.

 

Unraid 6.1.3

Asus Sabertooth 990fx r2.0 motherboard

AMD fx8350 processor

Sapphire R9 280X Dual-X OC gpu

32gb DDR3 1600 memory

 

Can you try this:  http://lime-technology.com/forum/index.php?topic=41922.0

 

Tell me if they work after.

Hi jonp, thanks for replying. I tried your new method before I posted my question but I just got errors I didn't understand.

Here's the xml from the vm before editing. Which of the lines should I change?

Fixed XML above.  Just copy and paste in the XML editor and tell me if that works for you.

Good and bad news. That allowed me to select an option from the installation menu so I selected the "automatic" option and it went through the installation and then when it rebooted, it crashed unraid No browser or command line access.

So I created a fresh vm for Ubuntu and made your xml changes and was able to select the language and also the correct install option from the list (tried both live and full installs) and it ran through some console stuff and then stopped at a point where it appeared to be configuring input devices. I pressed a couple of keys to see if it would respond and found myself at the unraid login prompt! which I'm pretty sure shouldn't happen from within a vm, especially as I'm passing through the graphics card.

 

Should I start a new thread for this or do you think it's related?

This is a bug relating to GPU pass through with a SeaBIOS VM and rarely occurs, but can happen.  If you try creating the VM using OVMF instead of SeaBIOS, that will not occur.

I tried creating the SteamOS vm using ovmf (including the usb fix) but I just get a black screen and quite a lot of disk and cpu activity. I thought you couldn't use ovmf if your GPU bios didn't support UEFI? Am I correct? My card does not have a uefi bios (regardless of what it might say in various places online and what it leads you to think from the blurb on the packaging). I have not been able to use ovmf at all up to this point.

I'm happy to schedule a session with you if that's the best way to get this working.

Thanks again for the help so far.
