That said, distros can ease the pain by backporting the libvirt patches for starting qemu from QMP rather than -help into current libvirt releases, although that becomes a matter for distros rather than this lis= t. >=20 > By the time 1.3 goes out, there should be a libvirt release with the > necessary support so if your using distro packages, you'll never notice= =2E Libvirt 1.0.0 will land in early November, and fully supports qemu.git, so you are correct that a released libvirt will be available prior to qemu 1.3: https://www.redhat.com/archives/libvir-list/2012-October/msg00403.html Additionally, there will probably be a release candidate in the next 48 hours, where you can use that tarball (rawhide will most certainly pick it up), so the pain of using libvirt.git to develop qemu.git will not last much longer. --=20 Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --------------enig36EA23FAF0C06031B035C09D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iQEcBAEBCAAGBQJQhpZ1AAoJEKeha0olJ0NqRH4H/R5UQcSGzIMRwuJp2GR1GeiX QK8aUPcTrD3koDPr0eKcXkJb2kBXV1EkILyM2GDkvDNMSkGbB6Qq+tIHqEjbQF5E Vy1UXyOeklnwp5s3QtWnz6g4Q2VxI5W1J8KFF/UEbcB2VdgoOU4dmdPBE59uuHse RxmG58gNp9TEP1vJq7IulKsFM5f4uA+bExuvTCe1lfFq6zxEJjsWb/O4L3MpJS4r /AmfWxqcSY3LPYqtxL3Av8ZoGcIxE9ecH3StDhBTDKw2OMOdAQ9KTQCoq6O4gJRL Vnmorca5F2eTX77SyMtsbSbH34O2B3KNi9paqmk92mJXhIa9rdL6P0eipXrXnfw= =dNUs -----END PGP SIGNATURE----- --------------enig36EA23FAF0C06031B035C09D--
