by Carlos Munoz 22 Dec '14

22 Dec '14

Hi, The migration of the libvirt project translations to Zanata is now complete. Translators can start working now at https://fedora.zanata.org/project/view/libvirt To use Zanata, you need to 1. Register in https://fedora.zanata.org 2. If you are not the maintainer of your project yet, contact the admin to add you as maintainer. 3. Follow the instruction http://zanata.org/help/cli/cli-configuration/ 4. Place the attached zanata.xml in the root directory of repository 5. (Optional) integrate "zanata push" and "zanata pull" to your build scripts. If you have any questions , feel free to contact the Zanata dev team. Regards, -- Carlos A. Munoz Software Engineering Supervisor Engineering - Internationalization Red Hat

[libvirt] [PATCH] docs: split typedef and struct definition for apibuild.py
by Claudio Bley 20 Dec '14

20 Dec '14

The members of struct virSecurityLabel[1] and struct virSecurityModel[2] were not shown in the libvirt API docs because the corresponding <field> elements were missing from the libvirt-api.xml. The reason is that apibuild.py does not cope well with typedef's using inline struct definitions. It fails to associate any info about the struct with the typedef and consequently cannot write out the members of the struct. Splitting the typedef and the struct definition into seperate statements as it is done for other structs works around this problem. [1]: http://libvirt.org/html/libvirt-libvirt-host.html#virSecurityLabel [2]: http://libvirt.org/html/libvirt-libvirt-host.html#virSecurityModel --- Seems I had to run "make" twice inside the docs folder before the changes were picked up. Besides, my email address has changed. If this this patch gets ACKed, I'd also adjust the AUTHORS file in a separate trivial patch. include/libvirt/libvirt-host.h | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) diff --git a/include/libvirt/libvirt-host.h b/include/libvirt/libvirt-host.h index 53b529f..0704672 100644 --- a/include/libvirt/libvirt-host.h +++ b/include/libvirt/libvirt-host.h @@ -108,12 +108,13 @@ typedef virStream *virStreamPtr; * a virSecurityLabel is a structure filled by virDomainGetSecurityLabel(), * providing the security label and associated attributes for the specified * domain. - * */ -typedef struct _virSecurityLabel { +typedef struct _virSecurityLabel virSecurityLabel; + +struct _virSecurityLabel { char label[VIR_SECURITY_LABEL_BUFLEN]; /* security label string */ int enforcing; /* 1 if security policy is being enforced for domain */ -} virSecurityLabel; +}; /** * virSecurityLabelPtr: @@ -142,12 +143,13 @@ typedef virSecurityLabel *virSecurityLabelPtr; * a virSecurityModel is a structure filled by virNodeGetSecurityModel(), * providing the per-hypervisor security model and DOI attributes for the * specified domain. - * */ -typedef struct _virSecurityModel { +typedef struct _virSecurityModel virSecurityModel; + +struct _virSecurityModel { char model[VIR_SECURITY_MODEL_BUFLEN]; /* security model string */ char doi[VIR_SECURITY_DOI_BUFLEN]; /* domain of interpetation */ -} virSecurityModel; +}; /** * virSecurityModelPtr: -- 2.2.0

[libvirt] [PATCH] Drop hle feature for Haswell CPUs
by Guido Günther 19 Dec '14

19 Dec '14

The intel-microcode 3.20140913.1 update disables TSX-NI (transactional memory instructions). When a server running libvirt is rebooted with this update, libvirt no longer considers the machine to have a Haswell CPU: # virsh capabilities | grep -A1 '<arch>x86_64' <arch>x86_64</arch> <model>SandyBridge</model> Since Intel disables the feature on their CPUs we shouldn't check for it as well to keep VMs using Haswell working.

[libvirt] [PATCH] virsh: add transient interfaces check for iface-unbridge
by Lin Ma 19 Dec '14

19 Dec '14

iface-unbridge(netcf interface backend) checks multiple interfaces attaching based on static configuration. If guests interfaces(says tun/tap devices) are attaching to the bridge, iface-unbridge doesn't check them, It causes the bridge is removed although it's in use by other guests.

[libvirt] virSecurityLabel
by Claudio Bley 19 Dec '14

19 Dec '14

Hi. Looking at the API docs, the virSecurityLabel is one of the undisclosed structs, making its members not publicly available. Is this a mistake? It seems the a virSecurityLabel or virSecurityLabelPtr retrieved by the virDomainGetSecurityLabel et. al. would be rather useless without being able to inspect the contents of the returned struct. Especially since the docs mention something about a 'label' field. Thanks. -- Claudio
