Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

I have no idea regarding 4.9+ kernel and ACS patch. You can check the kernel sources and look at the change log. It should be listed. See https://www.kernel.org/ and https://kernelnewbies.org/Linux_4.9 . Where did you read that kernel 4.9+ includes the ACS patch? I didn't see it, but haven't resear...

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

I've read on several forums that the acs override patch has been added since kernel version 4.9. I installed kernel 4.13 the other day and it doesn't work. Is this true or is it hit and miss depending on hardware? Just to be sure, you did modify your grub file to enable ACS and ran update-grub? If ...

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

Thanks odtech! I totally missed the comment.

You are right, the qemu command can't be commented. I usually copy the command option to the end of the script and the place a # in front. The bash script allows #, just not the qemu command.

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

@Foxybingo15: Could it be that your Windows 10 image file is damaged? Try download it again and use the new file then. Another user here had similar issues and it turned out it was because of a corrupted file. If the above doesn't help, have a look here: https://forum.level1techs.com/t/ryzen-virtual...

@Foxybingo15 : EDIT: In the start script, change the smp option to "smp 4" - you specified the architecture for my CPU, which supports hyperthreading, yours is different and doesn't support hyperthreading. When you first run the script to install Windows, specify the boot order to have it ...

Re: HOW-TO make dual-boot obsolete using kvm VGA passthrough

This is the result of the passmark test: https://www.passmark.com/baselines/V9/images/88733639138.png The result seems low. But I give only 2 core & 2 threads from the 7700. No OC. The 2D perf of the CG is pretty low too. That doesn't look too bad, particularly when you consider the no. of core...

Hello

Did you follow the 4th step of the first part?
You need to edit grub configuration and reboot.


After editing the grub file, make sure to run

Code: Select all

sudo update-grub

I did not try mounting my img file maybe its just simple as that. I use LVM formated drives and mount my volumes using kpartx. If you use image files, for example qc...

@HPMint: About Passmark, unless you forgot to use the ignore_msgr option it might be because you use the PC or fx440 machine type.

@juju: I noticed you use the standard "pc" (fx440) machine instead of "q35" - see my start script. In my case the "pc" (fx440) option always delivered bad performance. You cannot just change this option but would need to reinstall Windows. However, I have no idea which ...

@HPMint: I agree - leave your sound setup, it works! 2. If you have configured your network using brctl or editing the /etc/network/interfaces file, there might be remnants of the configuration left that mess up a Network Manager configuration.

Hey! Thanks for the great guide and thread. I'm completely new to xen (but with lots of experience using other virtualization stuff). I'm hoping to set up a xen hypervisor running off debian/ubuntu/mint/etc, then run a GPU passthrough to a Windows 7 VM. The GPU is an ATI Radeon 290 (think I saw the...
