  • Thread-topic: Blocking problem with booting the domU

Hello List,

My domU stops at the point, where it should start the init-process and gives no 
hint, why:
[....]
Xen virtual console successfully installed as xvc0
Event-channel device installed.
netfront: Initialising virtual ethernet driver.
i2c /dev entries driver
NET: Registered protocol family 17
xen-vbd: registered block device major 8
blkfront: sda5: barriers enabled
registered taskstats version 1
XENBUS: Device with no driver: device/vkbd/0
XENBUS: Device with no driver: device/vfb/0
XENBUS: Device with no driver: device/console/0
XFS mounting filesystem sda5
VFS: Mounted root (xfs filesystem) readonly.
Freeing unused kernel memory: 172k freed
udevd version 128 started
[end]

Now it idles and does nothing. If i connect via vnc, i get only the qemu 
console, don't know why?!
The domU-config:
------------------------------------------
xen0 ~ # cat /etc/xen/suse-default
name    = "suse-default";
memory  = 1024;
cpus = "0-7";
vcpus = 8;

kernel = "/boot/vmlinuz_domU"
extra=" root=/dev/sda5"

disk = [ 'file:/VirtualMachines/Templates/Suse_hda5,sda5,w' ]
vif = [ "mac=00:16:3e:1b:65:10" ];

vfb = [ 'type=vnc,vncunused=1' ]
vnc = 1
vncconsole = 0
keymap = "de"
------------------------------------------
As the kernel is "homemade" i am assuming that there must be something more 
that should be activated than only the xen-frontend-configs?

I want to have a smallest possible kernel, only containing the features i'ld 
need to boot into the paravirtualized image, so i deactivated most.

So what is happening between "freeing memory" and "starting init" that i could 
have broke?

Kind regards, Florian
