Hi,
I'm trying to
use a PV guest VM on Xen to help debug Linux.Â
I was using
VirtualBox to help debug Linux kernel by redirecting the
output of the serial port of the VM to a file in the host. I
can do it in VirtualBox.
[Why do I
want to achieve this?]
It is much
faster to reboot a VM than rebooting the physical machine.
I don't need
another machine to physically connect to the serial port of
the development machine.
I want to use
Xen for as many things as possible. ;-)
I tried to
google a tutorial or manual about how to configure it, but
didn't find any. :-(
In my
understanding, I need to do the following things:
1) I need to
add a line (something like "serial=") in the guest's
configuration file to specify the serial port device to the
VM;Â
2) I need
some configuration to redirect the output of the serial device
to a file in domU;
3) After
that, I can configure the kernel command line in the VM to
dump the kernel message via the serial port of the VM. (I know
how to do this step.)
âDid anyone
have tried this before and have some configuration I can
refer to? orâ
âCould
anyone give me some references that describes how to
configure the above three steps? â
I really
appreciate any help or suggestion or comment.
