我正在运行 Manjaro KDE，并已成功设置了带有 GPU 直通的 Windows 10 VM，用于 Windows 事物，它运行良好，直到我注意到一个奇怪的行为。当我尝试重新启动 VM 时，甚至随机重新启动时（我整晚都开着它，早上就发生了这种情况），VM 会将其状态从正在运行切换到暂停。如果我尝试恢复，我会收到此错误：
Error unpausing domain: internal error: unable to execute QEMU command 'cont': Resetting the Virtual Machine is required
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 65, in cb_wrapper

if ret == -1: raise libvirtError ('virDomainResume() failed', dom=self)
libvirt.libvirtError: internal error: unable to execute QEMU command 'cont': Resetting the Virtual Machine is required
为了让它再次运行，我必须强制关闭然后重新启动。我尝试用 Google 搜索此错误，但结果并不确定。一些 reddit 帖子提到了 ioapic，但没有说明在哪里添加它或如何添加。
有人能帮我解决这个问题吗？这是 VM xml。

答案1
在寻找解决方案之后，我再次查看了启动时在“/etc/default/grub”中传递的内核参数。此文件中的相关行如下
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 amd_iommu=on iommu=pt pcie_ports=compat pci=nommconf"
最初，我没有设置 ，pcie_ports我相信auto是默认设置。阅读这篇文章时，我注意到还有两个选项：native（出现在我偶然发现的一些教程中，但它不能解决我的问题） 和compat。
设置pcie_ports=compat解决了我的 Windows 10 VM 的重启和关机问题。
我之所以设置这个，pci=nommconf是因为我有一台非常老旧的 HP 打印机，它有一个集成读卡器，在 Windows 中会产生很多错误，dmesg而且非常不稳定。有了这个，我可以更好地利用这台打印机。
我不确定这会对pcie_ports=compat我的主机操作系统产生什么影响！所以我很想知道是否有人可以对这个问题提供更多的解释！
