Saya menggunakan Ubuntu 12,04 64-bit dan KVM, CPU saya adalah Core i5 3.3 GHz dan saya memiliki 8 GB RAM DDR3. Saya menjalankan Windows 7 di KVM dan ini sangat lambat. Rekan kerja saya menggunakan Debian pada konfigurasi PC yang sama dan dapat menjalankan Windows 7 dengan sangat cepat! Di mana bisa masalah saya?

UPD : Saya telah mengaktifkan Intel-VT sebelum menginstal KVM. Saya telah berhasil menginstal driver VirtIO, dan itu memberi saya beberapa kinerja, tetapi, misalnya, ketika saya membuka Firefox di Windows, bahkan mouse bergerak sangat lambat, dan GUI juga sangat lambat.
