no login prompt in vm console

no login prompt in vm console
虚拟机终端没有登录提示

用xm console命令登录Xen创建的虚拟机, 屏幕上只显示启动时的信息, 没有登录提示, 按多次回车也有没反应, 如下:

Mounting other filesystems:  [  OK  ]
Starting sshd: [  OK  ]
Starting crond: [  OK  ]
Starting anacron: [  OK  ]
Starting atd: [  OK  ]
Starting Avahi daemon... [  OK  ]
Starting HAL daemon: [  OK  ]
Starting puppet: [  OK  ]
Starting smartd: [  OK  ]
INIT: version 2.86 reloading

按文档Console handling指示
需要在/etc/inittab增加一行xvc0, 并注释其它tty配置

co:2345:respawn:/sbin/agetty xvc0 9600 vt100-nav
#1:2345:respawn:/sbin/mingetty tty1
#2:2345:respawn:/sbin/mingetty tty2
#3:2345:respawn:/sbin/mingetty tty3
#4:2345:respawn:/sbin/mingetty tty4
#5:2345:respawn:/sbin/mingetty tty5
#6:2345:respawn:/sbin/mingetty tty6

在/etc/securetty增加一行

xvc0

修改完/etc/inittab后运行

init q

使之生效

再次连接虚拟机终端, 出现登录界面

# xm console 14
INIT: Sending processes the TERM signal

至于为何没有自动添加参数, 原因不明, 有可能是BUG
Bug 463855 - No login prompt after headless serial console installation with virtualization
Bug 448429 - xm console requires DomU getty modification to point to xvc0
