libvirt-guests invokes functions in gettext.sh, so we need to
require gettext package in spec file.
Demo with the fix:
% rpm -q gettext
package gettext is not installed
% rpm -ivh libvirt-client-0.8.8-1.fc14.x86_64.rpm
error: Failed dependencies:
gettext is needed by libvirt-client-0.8.8-1.fc14.x86_64

[note to self - it might be possible to drop the nc dependency in the
future, once I finish my conversion from -migration exec: to -migration

Maybe worth adding a comment before this line, justifying the requires
(just like we did before the nc requirement):
# Needed by libvirt-guests init script
ACK with that nit addressed.

Does your conversion affect how libvirt uses ssh for general communication?
Pretty sure I've seen some part of libvirt (other than migration) use
nc + ssh for general communication to remote qemu (ie with qemu+ssh://).

git grep '"nc"' has two hits:
src/qemu/qemu_migration.c: const char *args[] = { "nc", "-U",
unixfile, NULL };
Will still need to exist for qemu 0.10.x and 0.11.x (so we'd need it for
RHEL 5.6, but not for Fedora or RHEL 6; we've already got other
RHEL-version-related checks in the specfile to make that a conditional
dependency).
src/remote/remote_driver.c: cmd_argv[j++] = strdup (netcat ?
netcat : "nc");
Oh wow - we need to convert remote_driver.c over to virCommand.
However, that's the only other use of "nc", and it involves running nc
on the remote host, not on the local host, so you _don't_ need to
'Requires: nc' just because you installed libvirt-client; rather, it
seems like it should be libvirt (the server package) that should be
requiring nc.
In other words, I think we have a missing dependency if you install
libvirt but not libvirt-client; the reality is that both packages should
require nc (and libvirt-client can make the dependency conditional if I
improve migration on newer qemu).

Would like to confirm it and make patch if it is needed indeed.

libvirt requires libvirt-client, so its impossible to install
it without libvirt-client already present.
