我需要创建一个具有 Q35 机器类型的 Windows VM。然而，尽管指定了 q35，但仍创建了 i440fx 机器。
创建于：
sudo virt-install \
--name wintest \
--boot uefi \
--ram 32768 \
--graphics spice \
--machine q35 \
--features kvm_hidden=on \
--hostdev 0a:00.0,address.type=pci,address.multifunction=on \
--machine pc \
--vcpus 4 \
--os-type windows \
--os-variant win10 \
--network bridge=br0 \
--console pty,target_type=serial \
--disk /home/boss/Downloads/Win10_1809Oct_English_x64.iso,device=cdrom \
--disk /home/boss/Downloads/virtio-win-0.1.164.iso,device=cdrom \
--disk path=/home/boss/testVM/wintest.img,bus=virtio,size=60

创建过程中命令行出现了一些错误，但我认为它们可能无关紧要，但它们是：

答案1
因为你无意中指定了--machine两次。
--machine q35 \
--features kvm_hidden=on \
--hostdev 0a:00.0,address.type=pci,address.multifunction=on \
--machine pc \
删除包含 的不适当行--machine pc \。
