Found an undocumented prereq: libfile-slurp-perl (debian package)
anyways; I had a look at what was in the back of my mind as 'the iscsi
thing' <> xt 4.0/4.1. It's basically all about --image-dev --swap-dev
# Physical volumes
# root = '/dev/full-dev ro'

disk = [ 'phy:/dev/iscsi/iqn.2008-10.net.hostice:is0.vps31/part,sda1,w'
> That looks OK except for a missing "]".
pre-4.1 there used to be an issue where a device like
wouldn't come through when used with the xen-create-image command. So
not really iscsi specific. Just very ..:.::..:-ish
Anyways. Steve fixed that between 4.0 and 4.1.
What I used to do (experimenting) was use an iscsi share for vm's which
needed to be able to instantly migrate. It wasn't anything special. Some
pre-shared targets of either 9 or 18GB / 1 or 2GB swap. I needed those
shares to be used with xen-create-image obviously.
As I said before I quit using this setup after a few random disconnects
which crashed vm's and even forced a couple of Dom0 reboots. (sort of
undesired behaviour as far as I'm concerned)
