[libvirt] [PATCH v3] add a boot option to do strict boot
by Amos Kong 19 Mar '13

19 Mar '13

Seabios already added a new device type to halt booting. Qemu can add "HALT" at the end of bootindex string, then seabios will halt booting after trying to boot from all selected devices. This patch added a new boot option to configure if boot from un-selected devices. This option only effects when boot priority is changed by bootindex options, the old style(-boot order=..) will still try to boot from un-selected devices. v2: add HALT entry in get_boot_devices_list() v3: rebase to latest qemu upstream Signed-off-by: Amos Kong <akong(a)redhat.com> --- As we discussed in the past, we need to introduce a general query-config command to tell libvirt the supported options.

[libvirt] conftest segfault
by Gene Czarcinski 19 Mar '13

19 Mar '13

One of the libvirt tests (conftest) has been segfaulting for some time with no indication of a test failure other than a message in syslog. I verified this by building libvirt-1.0.3-1 with mock. Gene

[libvirt] [libvirt-designer 1/2] Fix libvirt caps -> libosinfo platform short id mapping

[libvirt] [PATCH 0/5]Add startupPolicy attribute support for hard disks
by Guannan Ren 19 Mar '13

19 Mar '13

The set of patches is trying to add 'startupPolicy' attribute support to the source element of hard disks. Policy levels are using the mandatory, requisite, optional levels as originally documented. For the 'optional' policy, there is a little difference from CDROM and Floppy which only drop its source path, for disks, if missing, the checking function will drop their definitions, because qemu doesn't allow missing source path for hard disk. If guest is using per-device boot element for its devices, after dropping one or more bootable device, the boot order will not be contiguous, the way here I use is to reorder them to make them contiguous. In this way, I introduce two new bit-operating functions virBitmapNextLastSetBit: Search for the last set bit before certain position. virBitmapNextLastSetBit: Search for the last clear bit before certain position.

[libvirt] [ANNOUNCE] libvirt-glib 0.1.6 release
by Daniel P. Berrange 18 Mar '13

18 Mar '13

I am pleased to announce that a new release of the libvirt-glib package, version 0.1.6, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Prefer g_strlcpy over strncpy - Fix potential crashes in some error handling cases - Fix typo in gvir_config_init docs which broke vala binding - Use 'transfer none' for argv parameter in all init functions - Ensure stream data parameters are annotated to be guint8 arrays, not gchar, since they're not NULL terminated strings. - Replace FSF address with URL in copyright headers - Add API for changing Spice compression parameters. libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not yet guaranteeing that libvirt-glib libraries are API/ABI permanently stable. As of the 0.0.8 release, we have tentatively frozen the API/ABI with the intent of being longterm stable hereafter, but there is still a small chance we might find flaws requiring an API/ABI change. The likelihood of this is low, however, and we will strive to avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH v8 0/3] DEVICE_DELETED event
by Michael S. Tsirkin 18 Mar '13

18 Mar '13

libvirt has a long-standing bug: when removing the device, it can request removal but does not know when the removal completes. Add an event so we can fix this in a robust way. First patch only adds the event with ID, second patch adds a path field. Split this way for ease of backport (stable downstreams without QOM would want to only take the first patch). Event without fields is still useful as management can use it to poll device list to figure out which device was removed. Signed-off-by: Michael S. Tsirkin <mst(a)redhat.com> If there are no more comments I'll stick this on my pci branch. Changes from v7: - none, v7 was malformed series sent by mistake Changes from v6: - make empty event use data: {}, Markus prefers this Changes from v5: - Emit an empty event on unnamed devices in patch 1/3, as suggested by Markus Changes from v4: - Add extra triggers and extra fields as requested by Markus Changes from v3: - Document that we only emit events for devices with and ID, as suggested by Markus Changes from v2: - move event toward the end of device_unparent, so that parents are reported after their children, as suggested by Paolo Changes from v1: - move to device_unparent - address comments by Andreas and Eric -- Anthony Liguori Michael S.
