XenLinux: network access?

XenLinux: network access?

[Adhamh Findlay]

By default does XenLinux have ssh enabled?

I'd like to be able to use grub to boot into XenLinux and then configure 
that domains from there over ssh.  I don't know and can't tell from the 
docs if XenLinux has dhcp and ssh...

XenoLinux here means *kernel*. Whether you have ssh, dhcpd etc,
depends on which linux distribution you use. Add corresponding init.d
scripts to the default run-level.

ssh has nothing to do with Xen/Linux -- it's purely a matter for
how your distro filesystem is configured. The answer is probably 'yes'.

The default Xen/Linux kernel dhcp configured, but normally its
possible to use a user-space dhcp server (just like any other
linux system).

This depends on the Linux distribution you have installed, not on
XenLinux.

If your distribution doesn't have SSH enabled, you can use the virtual console 
to log in and configure it.  Alternatively, you can mount the virtual 
machine's filesystem in your normal Linux environment and tweak the settings 
there.

Xen is the product, XenLinux is the kernel. Okay, what is the difference 
between the xen.gz file and the vmlinuz-2.6.9-xen0 file?

I searched in the docs and couldn't find this distinction.  Its likely a 
linuxism that I don't understand.

Re: XenLinux: network access?

[Mark A. Williamson]

xen.gz is Xen itself - it runs at the highest privilege level and manages 
memory, CPU time and some low level hardware initialisation

vmlinuz-2.6.9-xen0 is a Linux kernel that has been built to run on top of Xen.  
It handles device drivers, the network stack, filesystems, etc.  It provides 
services to applications you run.

The distribution you run on top of the XenLinux kernel (which is on top of Xen 
itself) will be something like Debian, SuSE, Mandrake, Fedora, etc.  Things 
like SSH, FTP, HTTP servers will be provided by your distribution.

This is not 'linuxism', but 'xenism'.

xen.gz is the image of Xen virtual  machine monitor. Xen runs on "bare
metal", and is the very first thing loaded by grub. vmlinuz-2.6.9-xen0
is the image for XenoLinux kernel. It's loaded by Xen at the end of
Xen booting process.
