you. There seems to be a problem with EPEL repo libguestfs-1.0.85-1.el5.5 rpm
(x86_64) - for example it is very slow with VM filesystem copy as it does not
make use of KVM acceleration (running plain qemu).

/dev/kqemu and ofcourse its not there in case of CentOS/RHEL (5.4).  Im not yet
entirely sure why it does not use KVM - but I guess it can be missing from build
already. We are trying to rebuild src rpm on CentOS 5.4 but encountering still
some (probably dependency) problems.

libguestfs lets you edit virtual machines.  Supports shell scripting,
bindings from many languages.  http://et.redhat.com/~rjones/libguestfs/

As you noted, the answer is this line -- it's running the wrong qemu.

The simplest fix is just to change qemu by setting
LIBGUESTFS_QEMU=/usr/bin/qemu-kvm (see:
http://libguestfs.org/guestfs.3.html#qemu_wrappers)

In broader terms, I think this is an issue with how libguestfs is
built:

http://cvs.fedoraproject.org/viewvc/EL-5/libguestfs/libguestfs.spec?view=markup

http://kojipkgs.fedoraproject.org/packages/libguestfs/1.0.85/1.el5.9/data/logs/x86_64/build.log

  checking for qemu-kvm... no
  checking for qemu-system-x86_64... /usr/bin/qemu-system-x86_64
  checking for guestfwd support in /usr/bin/qemu-system-x86_64... no

Apparently we need to BuildRequire kvm (not qemu-system-x86) on EL-5.
I'll have a look at fixing this.

In your ~/.rpmmacros file, add this line:

%libguestfs_buildnet   1

It's a gnulib bug.  I'm not sure what, but you can generally skip
these, or report the bug directly to the gnulib upstream:
