我正在尝试从 ISO 在 VM 中安装 CentOS 7，但一直收到错误libxl_dom.c:892:libxl__load_hvm_firmware_module: failed to read BIOS file: No such file or directory。这是我的配置：
name = 'CentOS'
builder = 'hvm'
memory = '512'
boot = 'dc'
disk = [ '/srv/xen/centos/xvda.img,,xvda,rw', '/srv/xen/centos/disk.iso,,xvdb,cdrom' ]
vif = [ '','mac=00:16:3E:13:37:01,bridge=xenbr1,ip=172.20.0.2/28' ]
我使用 /srv/xen/centos/xvda.img 创建了truncate -s 10G xvda.imgdisk.iso，下载地址为：http://mirror.chpc.utah.edu/pub/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1611.iso。这是我尝试创建域来安装 CentOS 时的调试输出：

这是怎么回事？我做错了什么吗？这是一个错误吗？
答案1
就我而言，我在 Arch Linux 上从 AUR 安装了 XEN，升级后出现了问题。
在版本 4.8.0-5 中，SeaBIOS 已从软件包中删除（请参阅此评论)，因为常规 Arch 存储库中有一个 SeaBIOS 版本。要解决此问题，只需通过运行 来安装它即可pacman -S seabios。
