我想启动 Windows 10 的物理安装,因此我需要运行 xen HVM 版本。您有我可以遵循的教程吗?

我正在尝试在 ubuntu 20.04 上的 virt-manager 中使用 xen 创建一个新连接,因为我想创建一个 Windows 10 客户机,我将在其中传递我的显卡 RTX 2080 ti。这些是我已经完成的步骤:

  1. 我已经设置并配置了所有内容,使用 qemu 和 kvm 通过我的显卡,并且它可以正常工作。

  2. 我对 xen 做了一些如下配置:

a)创建此脚本:

!/bin/bash

if [ $# -eq 0 ]; then

echo "Require PCI devices in format: <domain>:<bus>:<slot>.<function>"

echo "Eg: $(basename $0) 0000:00:1b.0"

exit 1

fi

modprobe xen-pciback

for pcidev in $@; do

if [ -h /sys/bus/pci/devices/"$pcidev"/driver ]; then

echo "Unbinding $pcidev from" $(basename $(readlink /sys/bus/pci/devices/"$pcidev"/driver))

echo -n "$pcidev" > /sys/bus/pci/devices/"$pcidev"/driver/unbind

fi

echo "Binding $pcidev to pciback"

echo -n "$pcidev" > /sys/bus/pci/drivers/pciback/new_slot

echo -n "$pcidev" > /sys/bus/pci/drivers/pciback/bind

done

b)我一运行脚本,就收到此消息:

Binding 0000:01:00.0 to pciback


confirmed by :


root@ziomario-I9:/home/ziomario/Scrivania/# xl pci-assignable-list

0000:01:00.0

看起来不错,但是当我尝试使用 virt-manager 创建与 xen 的新连接时,我看到了以下错误:

xen 无法连接到 libvirt xen

我查看了 xen.log 文件,看到了以下内容:
