I forgot your CPU type, so I don't know about your case. But, as I'm using 4820K, I usually using 4 to 6 threads gave to VM, only use 2 threads for Fedora host. And most important is vCPU tweaks, especially CPU topology and Hyper-V.
For me, I usually set topology as "sockets=1 cores=6 threads=1" if using 6 threads from host. Then set cpuset= to let vCPU worked on pointed CPU threads. IME, set all threads as vCPU cores can got better performance on Windows 10. 2015-12-26 18:00 GMT+08:00 thibaut noah <thibaut.n...@gmail.com>: > Hello guys merry christmas ! o/ > My current issue is vm and host optimization, i use my windows 10 vm for > gaming purposes only (like most of us i think), problem is, to keep my > performances on windows high i drain too much ressources on my fedora host > thus making it almost useless (also when leaving the vm i most of the time > found myself unable to use fedora at all so i have to reboot...). > So is it possible to improve performances to the max on the guest without > almost killing the host ? > Should i consider switching my gear for a bi-xeon?
