Xen users - May 2013 - ERROR: Toolstack not specifed and nothing detected, bailing out!

I have just installed Xen by following
http://wiki.xen.org/wiki/Xen_Beginners_Guide

All in all pretty good, however it mentions using the xl toolset but when I
first installed only the xm toolset would work. This was great for creating
linux based domains but it gave me an error about hvm when I tried creating a
Windows domain.

I then apt-get install xen-tools-common and edited /etc/default/xen to specify
the xl toolset, rebooted and tried again.  This time when doing xl info the
system returned:

WARING:  Can''t find toolstack xl, fallback to default!
ERROR:  A different toolstack (xm) have been selected!

So I did apt-get remove xen-tools-common and rebooted and set /etc/default/xen
to defaults.  Now when I try xl or xm info I get: "ERROR:  Toolstack not
specifed and nothing detected, bailing out!"

And I''m stuck, I''ve googled the error but can''t find
anything and am not sure what to check now.

Thank you.

Ok now I did apt-get remove xen-tools then reinstalled, rebooted and now xm
works ok, when I try create a windows host I''m back to the following:

root@xen-1:~# xm create /etc/xen/windows8.cfg
Using config file "/etc/xen/windows8.cfg".
Error: Errors were found at line 2 while processing /etc/xen/windows8.cfg:
           builder=''hvm''

I''m sure this is because the guide I was following was using the xl
toolstack but it didn''t say how they enabled it..

Some of that wiki page strikes me as a bit odd, it looks a bit like
someone has done a search and replace xm->xl without considering the
context (Debian Squeeze, which uses xm by default)

Which Debian release are you using? If you are using Squeeze then IMHO
you should stick with xm.

You might have better luck with: http://wiki.debian.org/Xen

If on Squeeze did you install the qemu-dm-xen package?

Do you mean xen-utils-common? xen-tools-common is not a package which
exists in Debian and xen-tools is a 3rd party set of utilities for
working with Xen once you have it installed and working.

Even if you meant xen-utils-common I''m a bit confused what you have
done
here, are you trying to mix and match an installation from source with
the Debian binary package xen-tools-common? That isn''t going to work,
xen-tools-common is for use with the Debian binary package of Xen.

If you are installing from Debian packages only then I don''t understand
why you needed to install xen-tools-common by hand, since it should have
been pulled in by the dependencies when you install the xen-linux-system
package.

Likewise I don''t see how you were able to remove xen-utils-common
without also removing other critical xen packages.

Thanks Ian, 

Got it working again and am back to the original error:

root@xen-1:~# xm create /etc/xen/windows8.cfg
Using config file "/etc/xen/windows8.cfg".
Error: Errors were found at line 2 while processing /etc/xen/windows8.cfg:
           builder=''hvm''

here''s the config file:

kernel = "/usr/lib/xen-4.0/boot/hvmloader"
   builder=''hvm''
   memory = 4096
   vcpus=4
   name = "ovm-1734"
   vif = [''bridge=xenbr0'']
   disk =
[''phy:/dev/vg1/windows8,hda,w'',''file:/usr/src/windows8.iso,hdc:cdrom,r'']
   acpi = 1
   device_model = ''qemu-dm''
   boot="d"
   sdl=0
   serial=''pty''
   vnc=1
   vnclisten=""
   vncpasswd=""

I''m still getting my head around the system (clearly!) so apologies if
I''m messing up something too obvious...

xm apparently doesn''t tolerate leading spaces.

Which was news to me but when I removed a few experimentally it seemed
to accept those lines.

Oh wait, since xm parses these files as Python code its obvious why it
is whitespace sensitive. Stupid language...

Ian.

Aargh! As simple as that, you are a star - thank you!
