Недостатки графических представлений KVM

Question 1

Я новичок в KVM, и я испытываю слабую графическую производительность.

KVM : Asus UX305FA с мини-Ubuntu 17.10 с менеджером окон i3.

В качестве дисплея я использую Spice, а видео - QXL. Я установил агента / клиента Spice у обоих гостей.

Бедные выступления одинаковы с 2 гостями. Опыт лагги, и если я играю видео на YouTube, у него много разрывов.

В том же хосте, если я запускаю виртуальную машину Win10 в Virtualbox, у меня гораздо лучшие графические характеристики, и автоматическое разрешение на основе гостевого окна работает.

Что я могу попытаться улучшить графические возможности?

Spice , как предложил @ byte-commander, я создал новую виртуальную машину с Debian 9. В этом
