Ubuntu 12.04 64 비트 및 KVM을 사용하며 CPU는 Core i5 3.3GHz이며 8GB의 DDR3 RAM이 있습니다. KVM에서 Windows 7을 실행하는데 속도가 매우 느립니다. 동료는 동일한 PC 구성에서 Debian을 사용하며 Windows 7을 매우 빠르게 실행할 수 있습니다! 내 문제는 어디에 있습니까?

UPD : KVM을 설치하기 전에 Intel-VT를 활성화했습니다. VirtIO 드라이버를 성공적으로 설치했는데 몇 가지 성능을 제공했지만, 예를 들어 Windows에서 Firefox를 열 때 마우스도 매우 느리게 이동하고 GUI도 매우 느립니다.
