Hi Mark,

Well, I don''t have all the installed packages you do, but it''s
close:

root@xenhost:~# dpkg -l | grep -i xen
ii  libxenstore3.0                      4.0.1-1                     Xenstore
communications library for Xen
ii  linux-image-2.6.32-5-xen-amd64      2.6.32-30                   Linux 2.6.32
for 64-bit PCs, Xen dom0 support
ii  xen-hypervisor-4.0-amd64            4.0.1-1                     The Xen
Hypervisor on AMD64
ii  xen-linux-system-2.6.32-5-xen-amd64 2.6.32-30                   Xen system
with Linux 2.6.32 on 64-bit PCs (meta-package)
ii  xen-utils-4.0                       4.0.1-1                     XEN
administrative tools
ii  xen-utils-common                    4.0.0-1                     XEN
administrative tools - common files
ii  xenstore-utils                      4.0.1-1                     Xenstore
utilities for Xen

Looks like I''m missing:
ii linux-image-xen-amd64 2.6.32+28 Linux for 64-bit PCs (meta-package), Xen dom0
support, Xen dom0 support
ii xen-qemu-dm-4.0 4.0.1-2 Xen Qemu Device Model virtual machine hardware
emulator

The second one isn''t a surprise as I didn''t install Qemu due
to the fact the processesor on my machine doesn''t support hardware
virtulaization, but maybe something is wrong that I don''t have the
first one. I installed it myself with apt-get and now I''ve got:

root@xenhost:~# dpkg -l | grep -i xen
ii  libxenstore3.0                          4.0.1-1                     Xenstore
communications library for Xen
ii  linux-image-2.6.32-5-xen-amd64          2.6.32-30                   Linux
2.6.32 for 64-bit PCs, Xen dom0 support
ii  linux-image-xen-amd64                   2.6.32+28                   Linux
for 64-bit PCs (meta-package), Xen dom0 support, Xen dom0 support
ii  xen-hypervisor-4.0-amd64                4.0.1-1                     The Xen
Hypervisor on AMD64
ii  xen-linux-system-2.6.32-5-xen-amd64     2.6.32-30                   Xen
system with Linux 2.6.32 on 64-bit PCs (meta-package)
ii  xen-utils-4.0                           4.0.1-1                     XEN
administrative tools
ii  xen-utils-common                        4.0.0-1                     XEN
administrative tools - common files
ii  xenstore-utils                          4.0.1-1                     Xenstore
utilities for Xen

Just to see, I tried xend start again, but got the same error.

Continuing with your instructions, I did an ls -la /proc and there was no xen so
I ran the echo ''none /proc/xen xenfs defaults 0 0'' >>
/etc/fstab command specified, ran dpkg-reconfigure xen-utils-common and (as xend
was already in my path) ran xend restart.  Same error, so I thought a reboot
might be in order.  Unfortunately, even after a reboot, xend would not start
with the same errors as before.

I guess my biggest question is, how important is the xen-qemu-dm-4.0 package if
your processor doesn''t support hardware virtualization?  Does it
support other functions for xen and should I install it anyway?

Thanks for the suggestions thus far,

Scott

install package.  WAY easier and not only did it install, it actually boots into
a Xen kernel!  :)  Might not sound like much of an accomplishment to others, but
it''s light years ahead of where I''ve been stuck.  I did an
install of Squeeze RC1 with the base system only and then used apt-get to
install ssh and then xen-linux-system-2.6.32-5-xen-amd64 (I didn''t
install xen-qemu-dm-4.0 because my processor doesn''t support hardware
virtualization; part of why I chose Xen over KVM).  It all worked like a charm.
No errors on install and the reboot brought me into a Xen kernel with no errors.

difficulty.  I can''t get xend to start.  I''ve researched
several of what looked like key phrases in the error output, but most of the
similar errors are either several years old and relate to Xen 3 and, for one
reason or another, don''t look applicable to my circumstances OR are
rooted in not having a Xen kernel started up which I have confirmed I have.
Does anyone have any suggestions on how to troubleshoot based upon the output
below?  I have looked through dmesg, messages and kern.log (the /var/log/xen
directory is empty as is /var/log/pycentral.log) and I can''t seem to
find anything that stands out.
