Hi Andy,
thanks for the reply.
OK, so I purged all the xen-related packages and configs, and installed grub-legacy and
linux-image-686-pae. dpkg-query -l |grep xen returns nothing
/boot/grub/menu.lst looks OK, but to be safe I backed it up and generated a new one with
update-grub, and zeroed out /boot/grub2/grub.cfg
still, same problem when I drop back into console, destroy the running instance, and try
to boot.
Using config file "/etc/xen/travelkazoo.conf”.
Error: Boot loader didn't return any data!
Here are the non-default entries in /boot/grub/menu.lst:
title Debian GNU/Linux, kernel 3.2.0-4-686-pae
root
kernel /boot/vmlinuz-3.2.0-4-686-pae root= ro
initrd /boot/initrd.img-3.2.0-4-686-pae
title Debian GNU/Linux, kernel 3.2.0-4-686-pae (single-user mode)
root
kernel /boot/vmlinuz-3.2.0-4-686-pae root= ro single
initrd /boot/initrd.img-3.2.0-4-686-pae
Anything else you can suggest for me to try?
Best,
-John

Hi,
I’ve updated my VPS to Wheezy. Unfortunately, I can’t get it to boot.
Xen console returns
Booting instance: travelkazoo
Using config file "/etc/xen/travelkazoo.conf".

This indicates that the /boot/grub/menu.lst file cannot be parsed.
Maybe it does not exist, or contains the wrong things. On wheezy it
would be provided by the package grub-legacy.
I am not very familiar with xen - am I supposed
to run xm create in /etc/xen?
Nope, you don't even need an /etc/xen directory; the reference to
/etc/xen/travelkazoo.conf above is the config file of your VPS on
BitFolk's server.
My previous squeeze system’s backups do not have
a travelkazoo.conf file in /etc/xen. xm create /etc/xen/travelkazoo.conf doesn’t work.
xend does not exist, even though I have xen-linux-system-686-pae installed, which is
supposed to include it. So it obviously cannot run.
A guest virtual machine running under Xen does not require xend,
that's purely for the host (dom0) machine. In fact since Debian
lenny you require no Xen-specific software whatsoever.
For Debian wheezy the correct kernel package is linux-image-686-pae
which will pull in the specific kernel linux-image-3.2.0-4-686-pae.
xen utils installed is version 4.1, as is
xen-hypervisor-4.1-i386 (arch is i386). update-grub2 works fine, /boot/grub2/grub.cfg
exists and looks plausible, I’ve moved /etc/grub.d/10_linux to 50_linux so 20_linux_xen is
first in line once I run update-grub2. I’ve been searching like mad and can’t seem to
find anything else to try.
You should not be sing grub2, so this is probably the problem. You
need a /boot/grub/menu.lst which is provided by grub-legacy.
grub-legacy was probably removed during upgrade. If you install
grub-legacy it will probably want to remove grub2, which is fine.
It sounds like booting into rescue VM, chroot into install and
install grub-legacy will most likely fix things.
Can someone please give me a hint what I’m
missing, or do I need to reinstall squeeze from scratch and restore from backup? :(
Worst case would be to install Debian wheezy from scratch. Notes for
that are here:
https://tools.bitfolk.com/wiki/Self-install
but I don't think it will come to that.
Here are all relevant packages installed:
ii libc6-xen:i386 2.13-38+deb7u1 i386
Embedded GNU C Library: Shared libraries [Xen version]
ii libxen-4.1 4.1.4-3+deb7u1 i386
Public libs for Xen
ii libxenstore3.0 4.1.4-3+deb7u1 i386
Xenstore communications library for Xen
ii linux-image-2.6-xen-686 2.6.32+29 i386
Linux 2.6 for modern PCs (meta-package), Xen dom0 support
ii linux-image-2.6.32-5-xen-686 2.6.32-48squeeze4 i386
Linux 2.6.32 for modern PCs, Xen dom0 support
rc linux-modules-2.6.18-6-xen-686 2.6.18.dfsg.1-26etch2 i386
Linux 2.6.18 modules on i686
ii xen-hypervisor-4.0-amd64 4.0.1-5.11 i386
The Xen Hypervisor on AMD64
ii xen-hypervisor-4.1-i386 4.1.4-3+deb7u1 i386
Xen Hypervisor on i386
ii xen-linux-system-3.2.0-4-686-pae 3.2.57-3+deb7u2 i386
Xen system with Linux 3.2 on modern PCs (meta-package)
ii xen-linux-system-686-pae 3.2+46 i386
Xen system with Linux for modern PCs (meta-package)
ii xen-system-i386 4.1.4-3+deb7u1 i386
Xen System on i386 (meta-package)
None of the above are required. You can remove them all and install
linux-image-686-pae.
Cheers,
Andy
