v2v: Clarify the missing input format error message (RHBZ#1141723).
v2v: Prevent conversion of "blocked" and "paused" domains also.

Previously only "running" domains were blocked from conversion.
However "blocked" is essentially the same as running (on Xen it just
means the domain is running but waiting on an I/O resource).  And
"paused" domains probably shouldn't be converted either since their
disks are only crash-consistent.
run: Add p2v to the PATH.
v2v: Fix for 'grubby: bad argument --set-kernel: unknown option' (RHBZ#1141145).

I made a mistake while translating the Perl conversion code and
transcribed --set-default as --set-kernel.  grubby has no --set-kernel
option so it failed.

Thanks: Tingting Zheng
v2v: Add xvda -> sda etc mappings (RHBZ#1142004).

For Xen guests, a device can be presented twice as (eg) xvda and sda,
and therefore we should map any otherwise unmapped xvdX.

For non-Xen guests, this should have no effect.
Version 1.27.47.
sysprep: Clarify when --mount-options is used and what it does (RHBZ#1142186).
RHEL 7: Emphasize libguestfs-winsupport package (RHBZ#627468).

This RHEL-only patch changes the error messages when the
inspection code cannot find an operating system inside the guest
image.  For a Windows guest this may happen because the user has not
installed the separate 'libguestfs-winsupport' package.  Therefore we
emphasize that the user may need to install this package.

Notes:

(1) In RHEL there are two pieces of inspection code, the old Perl code
(deprecated upstream) and the new C core inspection API.  Therefore
this patch has to touch two places with essentially the same change.

(2) This patch doesn't try to be clever and detect if it was a Windows
guest.  This should reduce the chance of failure.

Output from (Perl) virt-inspector now looks like this:

 $ virt-inspector disk.img
 No operating system could be detected inside this disk image.

 This may be because the file is not a disk image, or is not a virtual machine
 image, or because the OS type is not understood by virt-inspector.

 If you feel this is an error, please file a bug report including as much
 information about the disk image as possible.

 RHEL notice
 -------------
 libguestfs will return this error for Microsoft Windows guests if the
 separate 'libguestfs-winsupport' package is not installed. If the
 guest is running Microsoft Windows, please try again after installing
 'libguestfs-winsupport'.

Output from guestfish (ie. C core inspection API) now looks like this:

 $ guestfish -i disk.img
 guestfish: no operating system was found on this disk

 RHEL notice
 -------------
 libguestfs will return this error for Microsoft Windows guests if the
 separate 'libguestfs-winsupport' package is not installed. If the
 guest is running Microsoft Windows, please try again after installing
 'libguestfs-winsupport'.
RHEL 7: Remove libguestfs live (RHBZ#798980).

This isn't supported in RHEL 7.
RHEL 7: Remove 9p APIs from RHEL (RHBZ#921710).
RHEL 7: Disable unsupported remote drive protocols (RHBZ#962113).

This disables support for unsupported remote drive protocols:

 * ftp
 * ftps
 * http
 * https
 * tftp
 * gluster
 * iscsi
 * rbd
 * sheepdog
 * ssh

Note 'nbd' is not disabled, and of course 'file' works.

We hope to gradually add some of these back over the lifetime of RHEL 7.
