在主机 Linux 和客户机 Windows 上对 AMD Ryzen 进行嵌套虚拟化

在主机 Linux 和客户机 Windows 上对 AMD Ryzen 进行嵌套虚拟化

我有一台带有 QEMU KVM 的 Ubuntu 18 主机。虚拟机 Windows 10(已启用 hyper-v)

我想在 Windows VM 上运行 Android Studio 模拟器。

在主机上我有 kvm_amd nested=1

VM 设置 #1:

<vcpu placement='static'>8</vcpu>

<cpu mode='host-model' check='partial'>
  <model fallback='allow'/>
  <feature policy='disable' name='hypervisor'/>
</cpu>

使用此设置,Windows VM 具有:

  • 固件虚拟化:是
  • VM 监视模式扩展:否

虚拟机设置 #2:

<vcpu placement='static'>8</vcpu>
<cpu mode='host-passthrough' check='none'/>

使用此设置虚拟机具有:

  • 固件虚拟化:是
  • VM 监控模式扩展:是
  • 但虚拟机很慢,无法运行
  • 如果我将拓扑更改为默认值以外的其他值,VM 将进入启动循环

如果需要更多信息,请告诉我。你能帮助我吗?

我最终让 qemu-kvm 与 Windows 11 Professional 客户端以及 Hyper-V 和 Docker Desktop 顺利运行。

这是我的设置,也许对其他人有帮助。无意做广告!硬件:

Gigabyte X570 I AORUS PRO WIFI
BIOS-Version F37a (Virtualization enabled, Hyperthreading disabled)
AMD Ryzen 9 3950X 16-Core Processor
64Gb RAM

软件:

OS: Centos Stream 8
Kernel: 4.18.0-448.el8.x86_64
libvirt 8.0.0
QEMU 6.2.0

/etc/modprobe.d/kvm.conf

options kvm ignore_msrs=1
options kvm_amd nested=1

我安装了没有 SecureBoot 和 TPM 的 Windows 11 Pro。请 Google 提供详细信息。

Shift+F10 to launch cmd in windows setup regedit goto “HKEY_LOCAL_MACHINE\SYSTEM\Setup” 
right-click “New ⇒ Key ⇒ LabConfig” “New ⇒ DWORD (32-bit) ⇒ 
BypassTPMCheck ⇒ 1” same for “BypassRAMCheck” and “BypassSecureBootCheck”
