Linux xd 5.10.0-16-amd64 #1 SMP Debian 5.10.127-1 (2022-06-30) x86_64 GNU/Linux
编辑2022-07-20
这个问题时有发生，目前，当 Xen 启动登陆 initramfs 时，我遇到了很多麻烦，请帮忙。
wiki 建议安装拇指驱动器或根目录（ mount -o remount,rw/root ）。
显然没有磁盘可见。完整的配置文件和dmesg等可以在Xen列表中找到，请：
https://lists.xenproject.org/archives/html/xen-users/2022-07/threads.html#00041
https://lists.xenproject.org/archives/html/xen-users/2022-07/msg00057.html
在我的 debian11 上，我安装了xen-hypervisor-4.14-amd64、xen-hypervisor-common、xen-system-amd64和xen-utils-4.14
但我无法启动 Xen，请帮忙。
理论上，安装Xen后，根据https://wiki.debian.org/Xen，我应该只运行：
dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
update-grub
不幸的是，引导中断和 grub 邮件列表在去年 3 月至 4 月期间对此进行了非常深入的争论 - 显然 multiboot2 不会解决这个问题：
https://www.mail-archive.com/[电子邮件受保护]/msg32020.html
显然所有问题都出在initrd。安装 Xen 后我需要重建吗initrd？我该怎么做？
我需要一些帮助，请。这还没有定论吗？是否有我可以使用的解决方法（在 Xen 上部分启动并在提示符下手动加载 Xen 工作所需的其余部分）？我应该如何进行？我将尝试在 grub、debian xen 软件包和 Xen 上将其注册为请求/错误 - 关于操作还有更多想法吗？
grub 邮件列表上的讨论指出了这一点：
https://wiki.debian.org/DebianInstaller/NetbootFirmware#The_Solution:_Add_Firmware_to_Initramfs
这看起来非常复杂且危险……这是前进的方向吗？
请问有人修补过 grub2 以便能够支持 Xen 所需的功能吗？
注意：我使用的是纯 Xen，而不是 Eve。

答案1
不幸的是 Xen 与该硬件不兼容。
为了可追溯性，这在 xen-devel 上进行了讨论：
https://xen.markmail.org/message/7jgv47pk5rsea4ef?q=+list:com%2Exensource%2Elists%2Exen-devel&page=6
该固件具有比 16 位更宽的段号，并且在启动期间 NVME 会对其进行调用，这是根本问题。
Xen 尚不兼容此类硬件。
正如 xen-devel 上的报道，一个好的灵魂总是有可能实现这个新功能（也许是一个新的超级调用 sun 函数）。或者所有硬件的发展足以让他们实现。
我将遵循人们的建议并迁移到带有 Quemu 的 KVM，因为不幸的是 Xen 与该硬件不兼容。
我还向 Acer 询问了 16 但 PCI 固件更新：
