我已成功Fedora-Live-Workstation-x86_64-21-5.iso使用以下配置在 Xen 中启动 Fedora LiveCD 映像 ( )：
name = 'fedora_x86_64'
memory = 1024
disk = [
'file:/path/to/Fedora-Live-Workstation-x86_64-21-5.iso,xvdd:cdrom,r',
'phy:/dev/vgxen/lvfedora_x86_64,xvda,w'
]
vif = ['bridge=xenbr0']
bootloader = 'pygrub'
bootloader_args = [
'--kernel=/isolinux/vmlinuz0',
'--ramdisk=/isolinux/initrd0.img'
]
extra = 'root=live:CDLABEL=Fedora-Live-WS-x86_64-21-5 rootfstype=auto ro rd.live.image quiet rhgb rd.luks=0 rd.md=0 rd.dm=0 nomodeset'
最后一行是从/isolinux/isolinux.cfg标题为“以基本图形模式启动 Fedora Live”的菜单项中提取的。
然而，过了一会儿，我看到的只是以下内容：
Mounting Configuration File System...
[ OK ] Mounted Configuration File System.
[ OK ] Started Show Plymouth Boot Screen.
[ OK ] Reached target Paths.
[ OK ] Reached target Basic System.
又过了一段时间，我看到：
Starting Dracut Emergency Shell...
Warning: /dev/disk/by-label/Fedora-Live-WS-x86_64-21-5 does not exist
Warning: /dev/mapper/live-rw does not exist
Generating "/run/initramfs/rdsosreport.txt"
Entering emergency mode. Exit the shell to continue.
Type "journalctl" to view system logs.
You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot
after mounting them and attach it to a bug report.
