Re: xen not booting from lvm

[gary%duzan.org@localhost]

=> I'm having an issue trying to move an existing xen guest from a file
=> to lvm. The config file is below. The /dev/vg0/fooarchive,raw is
=> fractionally larger than the original file (lvm rounded it up to 14G),
=> and I've dd'ed across the data (reported exact size of original file
=> transferred) and verified at least the start is identical (re-run dd
=> and running a cmp now)
=>
=> name = "fooarchive"
=> memory = "1000"
=> disk = [ '/dev/vg0/fooarchive,raw,xvda,rw' ]
=> # disk = [ '/opt/xen/fooarchive,raw,xvda,rw' ]
=> vif = [ 'mac=02:00:00:00:01:04, bridge=bridge0', ]
=> bootloader = "/usr/pkg/bin/pygrub"
=> vcpus = 1
=>
=> The image is a 32bit Ubuntu 14.0 LTS guest. Booting from the /opt/xen
=> runs fine, while from /dev/vg0 shows the Ubuntu boot menu (Press enter
=> to boot the selected OS...) then hangs. Running on NetBSD-7 STABLE
=> from 8th Feb. amd64, xen 45-4.5.2
=>
=> Has anyone seen anything similar or have any ideas?

   Perhaps try "phy" instead of "raw", and/or "/dev/mapper/vg0-fooarchive"
instead of "/dev/vg0/fooarchive". That's what I use on my xen 4.5
setup. I also use the new style, so "phy:/dev/mapper/vg0-lnx,xvda,w".

   Good luck...
