[libvirt] ANNOUNCE: libvirt-glib release 0.2.0
by Daniel P. Berrange 15 Dec '14

15 Dec '14

I am pleased to announce that a new release of the libvirt-glib package, version 0.2.0, 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) Changes in this release: - Support keyboard input device config - Annotate some unused parameters - Add support for new graphics attach API 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 currently guaranteeing that libvirt-glib libraries are permanently API/ABI stable. That said we do not expect to break the API/ABI for the forseeable future and will always strive 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] qemu: Auto generate a controller when attach hostdev and chr device
by Luyao Huang 15 Dec '14

15 Dec '14

https://bugzilla.redhat.com/show_bug.cgi?id=1174154 When we use attach-device add a hostdev or chr device which have a iscsi address or others (just like guest agent, subsys iscsi disk...), we will find there is no basic controller for our new attached device. Somtimes this will make guest cannot start after we add them (although they can start at the second time).

[libvirt] [PATCH V2 0/3] qemu: support update graphic device persistently
by Wang Rui 15 Dec '14

15 Dec '14

We can change vnc password by using virDomainUpdateDeviceFlags API with live flag. But it can't be changed with config flag. v1: https://www.redhat.com/archives/libvir-list/2014-November/msg00627.html diff to v1: according to Jan's suggestion, 1. (patch 1/3) change error number to VIR_ERR_OPERATION_UNSUPPORTED 2. (patch 3/3) add 'VIR_DOMAIN_XML_SECURE' to flags in initialization. 3. (patch 3/3) Introduce a new function qemuDomainFindGraphicsIndex. Free the old graphics def and replace it with the new one as what we did for DEVICE_NET.

[libvirt] [PATCH] conf: fix virDomainLeaseIndex cannot work when both parameter have lockspaces present

[libvirt] [PATCH] conf: fix crash when match a network iscsi hostdev with a host iscsi hostdev
by Luyao Huang 15 Dec '14

15 Dec '14

https://bugzilla.redhat.com/show_bug.cgi?id=1174053 When we use attach-device to coldplug a network iscsi hostdev, libvirt will check if there is already a device in XML. But if the 'b' is a host iscsi hostdev and 'a' is a network iscsi hostdev , libvirtd will crash in virDomainHostdevMatchSubsysSCSIiSCSI, because 'b' doesn't have a hostname. Add a check in virDomainHostdevMatchSubsys, if the a's protocol and b's protocol is not the same. backtrace like this: 0 0x00007f850d6bc307 in virDomainHostdevMatchSubsysSCSIiSCSI at conf/domain_conf.c:10889 1 virDomainHostdevMatchSubsys at conf/domain_conf.c:10911 2 virDomainHostdevMatch at conf/domain_conf.c:10973 3 virDomainHostdevFind at conf/domain_conf.c:10998 4 0x00007f84f6a10560 in qemuDomainAttachDeviceConfig at qemu/qemu_driver.c:7223 5 qemuDomainAttachDeviceFlags at qemu/qemu_driver.c:7554 Signed-off-by: Luyao Huang <lhuang(a)redhat.com> --- src/conf/domain_conf.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 5cf0b1a..eb63c93 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -11184,7 +11184,9 @@ static int virDomainHostdevMatchSubsys(virDomainHostdevDefPtr a, virDomainHostdevDefPtr b) { - if (a->source.subsys.type != b->source.subsys.type) + if (a->source.subsys.type != b->source.subsys.type || + (a->source.subsys.type == VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI && + a->source.subsys.u.scsi.protocol != b->source.subsys.u.scsi.protocol)) return 0; switch (a->source.subsys.type) { -- 1.8.3.1

[libvirt] [PATCH 0/3] Fix starting/stopping of netdevs when starting/stopping CPUs
by Laine Stump 15 Dec '14

15 Dec '14

The first two patches provide a cleaner, more complete fix to a fix that was recently pushed for https://bugzilla.redhat.com/show_bug.cgi?id=1081461 While the original patch does fix the symptoms in the report, applying these two additional patches handle some situations that weren't addressed by the original. Patch 3 fixes a similar problem with tap devices when the newly added macTableManager='libvirt' is used. It should make migration of guests with this new type of network connection work properly with no loss of network connectivity (including once post-copy migration is working).
