Running Xen at a colo

Running Xen at a colo

[devsubs]

>From reading the docs, installing Xen means getting the binary, installing it
and setting up your virtual servers.

I want to install Xen and send the machine to colocation provider. Does that
mean once I set it up and am able to logon at the colo provider, I will be
ready to create and manager domains?

i.e. does the Xen binary come with everything needed to run Xen?

You'll need various user space libraries and utilities installed in order to 
run the management utilities.  The Xen utilities are distributed with the 
binary installer but not all their dependencies.  See the FAQ for a list of 
Debian packages.  For other distros, you'll need to be sure you have the 
equivalents installed.

Cheers,
Mark

What I mean to ask is at what point will I cease to require physical access to
the machine in order to get virtual servers running?

How far into the process will I be able to send the machine to the colo
provider, ie the point at which getting an SSH prompt whenever the machine is
rebooted will enable me to manage processes?

After Linux Domain 0 is booted from Xen, you don't need any further
physical access.  (But actually it's also possible to have "normal"
Linux on a remote machine, do the grub setup etc and then reboot with
Xen.)

However, I'd suggest to simply test on a local machine first and then go
to the provider, just to make sure it works etc.

Regards,
Milan

Once you've installed Xen itself and XenLinux and they boot OK, with all your 
devices working you should be able to do everything else remotely (install 
the userspace prereqs, the Xen management tools, etc).

HTH,
Mark

And if you're really good, you can get the system booting Xen without 
physical access. Though serial console is, on occasion, a handy thing to 
have, once you've set everything up as it should be, you shouldn't need 
it again.

Indeed - it's theoretically possible to install Xen on a remote box, reboot 
and have it Just Work(TM).

Unfortunately if you make a mistake you've got to wait for someone at your 
provider to go boot your machine into something sensible again - speaking 
from experience, that makes sorting out mistakes rather time consuming.

Serial console is definitely nice to have if you can get it at your colo 
provider.

Cheers,
Mark
