SubjectRE: VMWare Workstation 6 for debugging Linux Kernel (!)
Hi roland,
It's really an interesting feature, IMHO, maybe the UML would be no
more needed.
thanks very much;-)

Regards,

> Debugging Linux kernels with Workstation 6.0
> We just quietly added an exciting feature to Workstation 6.0. I believe it
> will make WS6 a great tool for Linux kernel development. You can now debug
> kernel of Linux VM with gdb running on the Host without changing anything in
> the Guest VM. No kdb, no recompiling and no need for second machine. All you
> need is a single line in VM's configuration file.

> To use the new feature, grab the latest build of WS6 here:

>
> Put this line into configuration file of your Linux VM:
>
> debugStub.listen.guest32=1
>
> Now whenever you run the virtual machine, you'll see the following on the
> Host console:
>
> VMware Workstation is listening for debug connection on port 8832.
>
> Run gdb on the Host, reference it to the kernel with symbols and attach to
> the virtual machine:
>
> % gdb
> (gdb) file vmlinux-2.4.21-27.EL.debug
> (gdb) target remote localhost:8832
>
> That's it. The VM is blocked now, so you can "continue" it and "^C" back to
> gdb. Breakpoints, single step, memory inspection - all this works as usual.
> If you have SMP VM, then each VCPU is mapped on a thread, so use "info
> threads" and "thread NN" to switch between them.

> The kernels with symbols are sadly lacking on most distributions, but if you
> use RHEL then this website may help (look for kernel-debuginfo rpm):

> The gdb support in WS6 is experimental, so there may be rough edges here and
> there. Please post on community forums if something doesn't work right or if
> you have a suggestion:

> There are more debugging specific features in WS6 (for example, you can use
> gdb hand-in-hand with Record/Replay!). I will describe them shortly.
