[PATCH] inspection: Fix fstab device mapping for >26 disks
by Matthew Booth
The regular expression matching disk name assumed that there was only a single
letter suffix. This change handles a naming scheme for any number of disks.

Libguestfs & ubuntu 11.10 problems
by KoDer
HI, All.
I face problems when try to use libguestfs in new ubuntu 11.10.
1) My current version of libguest (1.12.0, binaries taken from
libguestfs site) can't boot vm with new kernel.
You can find log of libguest-test-tool in attachment. I try force
it to boot 2.6.38-11 kernel instead of
3.0.0-12 (which is default), but get the same result (error)
2) I can't compile libguestfs from sources:
make libguestfs-1.12.7 leads to:
.........

[PATCH 1/9] Partially fix --disable-erlang
by misc＠zarb.org
From: Michael Scherer <misc(a)zarb.org>
Without this, configure will always enable erlang, no matter what
argument are passed. Now, we can disable it, even if configure still
need the erlang compiler for some obscure reason.

[PATCH 3/7] generator: Add new return types to ABI: RLenNode and RLenValue
by Alex Nelson
RLenNode and RLenValue are similar to RLenType, though with one less
argument. This required adding one processing function for OCaml and
Python.

Man pages for virt-p2v-server?
by Greg Scott
I just installed virt-v2v 0.8.3.1 on a Fedora 14 VM and was getting
ready to set up a P2V migration. But the virt-p2v-server man pages only
tell me about the GPL and that's it. Is the documentation for that
.conf file someplace else now? Or don't I need it anymore?
Thanks
