Hi,

I have put that line in to the config file but now it freezes even before it starts to boot the OS. Here is the complete output after running xm create with "extra = 'xencons=tty'" in my config file:

[root@localhost vm]# xm create -c test4.cfg

However, an update: I just tried booting it in to different run-levels using the 'extra' command in the config file, and it will boot in to run-level 1 but nothing higher. Still nothing in the log files or anything though.

Cheers,

Andrew

Try to boot with extre='xencons=tty' in config file or xencons=tty in
kernel line when using pygrub.

BR,

Betreff: [Xen-users] DomU freezes during boot

Hi,

I am trying to boot a freshly installed DomU (using xen-tools and rinse) 
of CentOS 5 64bit. It starts booting the operating system but it freezes 
every time after starting SSH:

INIT: version 2.86 booting
                Welcome to  CentOS release 5.2 (Final)

Nothing comes up, it just stops there. I have tried mounting the HDD 
image of the domU on my host to access the log files but there does not 
appear to be anything of use. This is the dmesg log file on the domU:
