O motivo parece ser específico dos processadores Intel com o passo B3 ou mais antigo . No meu caso, eu tive um dos processadores Intel Xeon X3210 B3 mais antigos. Concluir; Se você quiser rodar o Windows XP 32bit no Hyper-V com um processador Intel, certifique-se de ter um passo mais avançado que o B3. (Você precisará de suporte ao vTPR)
Operating systems prior to 2003 Server, which includes XP and 2000, do not have lazy IRQL. When an operating system without IRQL runs in Hyper-V on a processor without vTPR, disk performance is slow. Switching to a vTPR processor makes the problem go away. hughescj and I have seen this. The point is that the solution is not to rewrite an old operating system, but to use vTPR processors.
