Hi Thomas, awesome work! I've changed my (gaming-)setup (2x Xeon E5-2670 (8 real cores per CPU)) to the following: VM1 and VM2: Each gets 4 real cores on CPU0; Emulator-Thread is pinned to the respective Hyper-Threading cores. VM3: 6 real cores on CPU1; Emulator-Thread is pinned to the resp

Hi, I've two E5-2670 CPUs and want to pin a VM to a node. CPU pinning works fine, however memory allocation seems to happen randomly. Sometimes it is done on node 0, sometimes on node 1. My VM config: http://pastebin.com/raw/J6trq7gJ I'm on Arch Linux Kernel 4.8.13-1 with libvirt 2.4.0-2 Any id

hich I'm assuming is a performance limitation of this early CPU. Host achieves 74,000 random 4kB reads per second, while guest only sees 33,000. I haven't played around with that enough to pin down the cause. Cheers, Nicholas Sherlock On 5 November 2016 at 02:56, Jan Wiele wrote: Hi

Hi everyone, inspired by [1] and in need of a new computer, I settled with the idea to get 2x Xeon E5-2670 and an ASRock Rack EP2C602. Its main purpose is to provide 2-3 (mediocre) gaming VMs with (Nvidia) GPU- passthrough. Before I buy these parts, I have some questions: * Has anyone experien

You are not alone. I have had the exact same symptoms. Wanted to build a "gaming" machine with two seats for playing Heroes of the Storm. Performance was bad. Very low fps especially in fights. No difference between low and high graphic settings. Nevertheless, graphic benchmarks, like 3D mark,

Hi, I also get very good results with 3DMark. But CPU intensive tasks/games (like Heroes of the Storm) aren't running that good (CPU pinning, isolcpus etc used). Could you share the benchmark results of Cinebench with us (CPU and OpenGL)? Regards, Jan Am 27.02.2016 um 14:49 schrieb gui-...@netco
