About mounting qcow images under Linux, see http://ask.xmodulo.com/mount-qcow2-disk-image-linux.html.

Make sure you DON'T run the VM at the same time!!!

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

@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. When using Network Manager to configure the bridge, you...

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

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...

@juju: Thanks for the reply. I hope you didn't buy the benchmarking software because of my request. Passmark can be had for a trial, and the userbenchmark I suggest now is free. The good things about benchmarks is that it allows you to compare with similar configurations, and to discover problems in...

Re: My experience with LM (1 month)

I was pretty much in the same situation 5 years ago, when I dual booted Linux and Windows. There were things that Linux couldn't do, or more correctly, where companies decided to not support Linux. Back then I learned about virtualization and a technology called VGA passthrough. Since then I run Lin...

Re: [virt-manager] LinuxMint 18.2 Cinnamon runs in software rendering mode

I have not had good experience with virt-manager. Somehow it always seems to need some manual fine tuning or command additions inside the xml file to make things work, or to get some decent performance. If I already have to tinker with the xml file, I might as well use the qemu command and write a s...

Looking at the script, there are some typos and other issues - see bold text: 1. machine type=pc -- unless you have a good reason, try q35. Note that if you installed Windows already, you will need to reinstall when changing the type. 2. -m 2300 -- this is very little memory for your Windows VM. Th...
