[Xen-users] Kernel panics

[Yves Dorfsman <yves@xxxxxxxxx>]

Hi,

I'm knwe to XEN, and having the usual panic problem.
XEN (3.0.4.1) loads, then the kernel loads, then it says:
"Please append a correct "root=" boot option"
"Not syncying VFS unable to mount root fs on unknown-block(2,0)"
(sort of, I'm catching this just before it reboots !).

I've googled, and it seems that the typical two sources of this problems 
are invalid initrd and/or missing drivers in the kernel. So before I turn 
mad, I've got a bunch of questions I'd be very happy if somebody could 
help me with:
Do you HAVE to have an initrd, or if you managed to put all the necessary 
drivers in the kernel, you should be able to boot without an initrd ?
My root partition is formated with JFS. Can this be an issue, or as long 
as I have the JFS drivers in the kernel I should be fine ?
Is there a way to capture the console output, short of using the serial 
line (or a digital camera :-) ?
Or a way to make it stop and wait for a key to be pressed before it 
reboots ?
When I do use an initrd, I get a segfault from the linuxrc.
Depending what version of mkinitrd I use I get different results, a lot of 
the time I can't even mount the gunzip resulting file, and when I can 
mount it, I get a lot of empty directories.... Is there a better way of 
producing the initrd ?
Thanks.


Yves.
