[libvirt] [PATCH] spice: expose the disable file transfer option
by Francesco Romani 06 Jan '14

06 Jan '14

spice-server offers an API to disable file transfer messages on the agent channel between the client and the guest. This is supported in qemu through the disable-agent-file-xfer option.

[libvirt] [PATCHv2] Fix explicit usage of default video PCI slots
by Ján Tomko 06 Jan '14

06 Jan '14

Do not leave the PCI address of the primary video card set to the legacy default (0000:00:02.0) if we're doing two-pass allocation. Since QEMU 1.6 (QEMU_CAPS_VIDEO_PRIMARY) we allow the primary video card to be on other slots than 0000:00:02.0 (as we use -device instead of -vga). However we fail to assign it an address if: * another device explicitly uses 0000:00:02.0 and * the primary video device has no address specified On the first pass, we have set the address to default, then checked if it's available, leaving it set even if it wasn't. This address got picked up by the second pass, resulting in a conflict: XML error: Attempted double use of PCI slot 0000:00:02.0 (may need "multifunction='on'" for device on function 0) Also fix the test that was supposed to catch this. --- v1: https://www.redhat.com/archives/libvir-list/2013-December/msg01125.html v2: no functional change rewrote the commit message to mention that this only happens with QEMU 1.6 and (hopefully) explain what 'this' is more clearly src/qemu/qemu_command.c | 50 +++++++++++++++++++++--------------------------- tests/qemuxml2argvtest.c | 3 ++- 2 files changed, 24 insertions(+), 29 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index d723dc8..2a64cd1 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -2379,7 +2379,6 @@ qemuValidateDevicePCISlotsPIIX3(virDomainDefPtr def, size_t i;

[libvirt] ANNOUNCE: Oz 0.12.0 release
by Chris Lalancette 03 Jan '14

03 Jan '14

All, I'm pleased to announce release 0.12.0 of Oz. Oz is a program for doing automated installation of guest operating systems with limited input from the user. Release 0.12.0 is a bugfix and feature release for Oz. Some of the highlights between Oz 0.11.0 and 0.12.0 are: * Fixes to concurrent oz-install invocations * Python 3 compatibility in the test suites * Support for Ubuntu 12.04.3 * Support for Mageia * Allow a MAC address to be passed in (instead of auto-generated) * Support for RHEL5.10 * Support for Ubuntu 13.10 * Use lxml instead of libxml2 for XML document processing (it has much better error messages) * Remove the unused "tunnels" functionality * Support FreeBSD 10.0 * Remove deprecated functions from the Guest class * Speed up guest customization on guests that support NetworkManager * Follow subprocess commands as they are executed (makes debugging easier) * Ensure that any paths from the user are absolute, otherwise things don't work properly * Add support for OpenSUSE 13.1 * Add support for Fedora 20 * Add support for RHEL-7 A tarball and zipfile of this release is available on the Github releases page: https://github.com/clalancette/oz/releases . Packages for Fedora-19, Fedora-20, and EPEL-6 have been built in Koji and will eventually make their way to stable. Instructions on how to get and use Oz are available at http://github.com/clalancette/oz/wiki . If you have questions or comments about Oz, please feel free to contact me at clalancette at gmail.com, or open up an issue on the github page: http://github.com/clalancette/oz/issues . Thanks to everyone who contributed to this release through bug reports, patches, and suggestions for improvement. Chris Lalancette
