The problem I'm running into is with CPU performance. I did not find many guides on the topic, so I wanted to share how I accomplished it in a straightforward way. Faster processors, more cores, and SSD storage will provide better VM performance. I’ve never had much luck with QXL. My setup has a Intel i7 6800k. (Sorry if this is a little rambly I am very tired) There's probably ways to improve the disk performance (USB isn't going to be the fastest way to provide a block device I suspect) and the graphics performance (using virtio-gpu so the guest has an actual 3D-capable device), but for the CPU, there isn't really anything beyond "use a faster host CPU". qcow2,backing_fmt=qcow2 -f qcow2 windows-cad. I use Windows 10 VMs from time to time for non-intensive operations (teams, msword, etc). g. About 3 months ago I noticed some sluggishness in Windows 10. Ok wow. Try changing it to a SATA bus.

Performance is not good enough for occasional use. I'd like to get away from dual-booting, and run my Windows 10 installation virtualized under KVM+libvirt+qemu. High Performance VM Help (Windows 10 inside Linux Mint) Hi all, I'm no expert, but you would probably get better performance running Windows through a KVM/QEMU virtual machine. 3 With QEMU/KVM the performance is much better, still a little stuttery, but no freezes or CPU spikes. Maybe for your specific use case, but not overall.

In most cases you want to use your high-performance graphics card in PCIe slot #1. 2+ and install the excitable on the guest (obv enable virgl acceleration on your qemu vm). Parallels, in its latest and greatest iteration, can virtualize up to DirectX 11 feature set, using the Metal gpu on your host Mac.

That kvm instance was able to run the original vm without any modification. Basically, unless you have some kind HPC workload IMO, if you have an emphasis on strong 3D accel / visuals performance on a Windows host, VMWare is what you need atm. It is a clear benefit of Qemu+KVM, though I do not use this feature at all. Problem: The issue is I can't get the VMWare SVGA driver to work in a Windows 10 guest. Naturally that won’t be as performance as bare metal Boot Camp. Functionality is excellent on Linux; however, Windows support is still sparsely documented [Qemu-devel] [Bug 1788665] Re: Low 2D graphics performance with Windows 10 (1803) VGA passthrough VM using "Spectre" protection.
