2.5.72 as VMware guest doesn't boot

2.5.72 as VMware guest doesn't boot

[Peter Braam]

Hi, 

I'm trying to boot a 2.5.72 guest in VMware workstation 3.2. 

It uncompresess the kernel, says it is booting linux, and that's the
end of the console messages.  

I have the feeling that I have possibly grossly misconfigured the
kernel. Does someone have a working .config file?

Just in case it's something more interesting, kgdb (which hasn't hit
it's initial breakpoint yet) shows:

(gdb) target remote /dev/ttys0
Remote debugging using /dev/ttys0
0x3c0a2965 in ?? ()

Thanks for any help.

Did you compile the VGA Console in the kernel ?

Kernel facilities for tracking file accesses

[J.C. Wren]

	Does any facility exist in the 2.4 and up kernels for logging *every* open, 
read, write, seek, close, etc call?  I'm trying to debug a problem in a 
package I don't have source to, and I'm trying to prove that it's not 
applying a configuration path option to files it's opening.  

	Ideally, I'd like a kernel module I can load that I can apply a regexp or 
limited pattern matchng to, and will log a selected group of operations as 
defined by a bitmask or other configuration option.  I would prefer something 
that monitors the entire system, rather than trying to sandbox this 
particular program (it runs as a daemon).

	Do the kernels have facilties for such tracking?

I'm currently working on Robert D. Russell's "Fast Kernel Tracing", see
his homepage http://www.cs.unh.edu/~rdr/ for the paper & distribution.
This is for kernel 2.4.0-test9, though.

The most recent version I'm working on is for 2.4.21, should support
on-the-fly log flushing and work on smp (not much tested though, it
began to work yesterday :) ). It might be ported to 2.5 without too
much work.

Hoping this might meet your needs,
Samuel Thibault

Can't you just use strace against the daemon?

How about the Linux Trace Toolkit?
