[libvirt] ANNOUNCE: Oz 0.13.0 release
by Chris Lalancette 07 Mar '15

07 Mar '15

All, I'm pleased to announce release 0.13.0 of Oz. Oz is a program for doing automated installation of guest operating systems with limited input from the user. Release 0.13.0 is a bugfix and feature release for Oz. Some of the highlights between Oz 0.12.0 and 0.13.0 are: - For Fedora, if the user specifies a version, but that isn't supported yet, try the last supported version (in this case), as that will often work. - Fix a regression where we forgot to force the qcow2 image type - Allow installs that use more than one installation device - Add support for RHEL 6.5 - Rename OEL-6 to OL-6 - Add support for Ubuntu 14.04 - Add Windows 8.1 support - Add CentOS-7 support - Add the ability to specify kernel parameters in the TDL - Make sure to remove dhcp leases from guests after the install - Fix support for FreeBSD - Add in support for TDL "precommands"; these are commands that are run *before* package installation - Fix up file locking - Add support for RHEL 5.11 - Remove Ubuntu ssh keys at the end of installation - Add support for Ubuntu 14.10 - Add support for XInclude, for merging various TDLs together - Add Fedora 21 support - Add support for ppc64 and ppc64le A tarball and zipfile of this release is available on the Github releases page: https://github.com/clalancette/oz/releases . Packages for Fedora-20, Fedora-21, Fedora-22, EPEL-6, and EPEL-7 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

[libvirt] [PATCH v4 0/9] Introduce display of IOThreads Information
by John Ferlan 06 Mar '15

06 Mar '15

v3: http://www.redhat.com/archives/libvir-list/2015-February/msg00593.html Changes since v3: (from code reviews) - Updated to use 1.2.14 not 1.2.13 - Change struct from virDomainIOThreadsInfo to virDomainIOThreadInfo - Remove the resources and nresources from virDomainIOThreadInfo and of course all associated code as well as changing the remote struct from iothreads_* to iothread_ - Create separate routines for virDomainGetIOThreadsInfo, virDomainGetIOThreadPin, and virDomainPinIOThread... and of course all the accompanying code - Use EnterMonitor instead of EnterMonitorAsync Still need to generate a v3 of the python code, but I'll wait for this to be reviewed first. John Ferlan (9): Implement public API for virDomainGetIOThreadsInfo remote: Implement the remote plumbing for virDomainGetIOThreadsInfo qemu: Implement the qemu driver fetch for IOThreads virsh: Add 'iothreadsinfo' command Implement public API for getting/setting specific IOThread pinning remote: Plumbing for getting/setting specific IOThread pinning domain: Introduce virDomainIOThreadsPin{Add|Del} qemu: Add support to get/set specific IOThread pinning data virsh: Add iothreadpin command daemon/remote.c | 123 ++++++++- include/libvirt/libvirt-domain.h | 41 ++- src/conf/domain_conf.c | 64 +++++ src/conf/domain_conf.h | 10 + src/driver-hypervisor.h | 24 +- src/libvirt-domain.c | 227 ++++++++++++++++- src/libvirt_private.syms | 2 + src/libvirt_public.syms | 8 + src/qemu/qemu_driver.c | 526 +++++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 143 ++++++++++- src/remote/remote_protocol.x | 61 ++++- src/remote_protocol-structs | 43 ++++ src/rpc/gendispatch.pl | 2 + tools/virsh-domain.c | 216 ++++++++++++++++ tools/virsh.pod | 38 +++ 15 files changed, 1521 insertions(+), 7 deletions(-) -- 2.1.0

[libvirt] ANNOUNCE: Libvirt Designer version 0.0.2 released
by Daniel P. Berrange 06 Mar '15

06 Mar '15

I'm pleased to announce the second release of the libvirt designer library, version 0.0.2 ftp://ftp.libvirt.org/libvirt/designer/libvirt-designer-0.0.2.tar.gz The release is signed ftp://ftp.libvirt.org/libvirt/designer/libvirt-designer-0.0.2.tar.gz.asc with the GPG key having the fingerprint DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) In this release: - Bumped soname & version for ABI change - Remove use of deprecated libosinfo calls - Fix various memory leaks - Treat errors loading the libosinfo DB as non-fatal as some data may be successfully loaded - Improve building of libosinfo short-id from libvirt capabilities information - Expose the libosinfo DB object via a property on the domain object - Don't set PKG_CONFIG_PATH for g-ir-scanner - Auto-generate list of AUTHORS - Avoid redefining _FORTIFY_SOURCE macro - Fix & add gtk-doc introspection annotation - Add Vala APi binding - Add support for floppy & CDROM devices - Use libvirt style libtool versioning csheme - Add API to set list of installed drivers - Add API for querying supported devices - Remove many bogus assumptions in disk bus handling - Populate clock settings, input devices & console - Add API for enabling sound devices - Add AP ifor enabling choice of graphics backends - Add SPICE agent if using SPICE - Add API for enabling USB redirection - Add API for enabling smartcard devices - Add API for enabling video devices - Import latest compiler warnings from gnulib - Avoid using deprecated libvirt-gconfig APIs - Rename virtxml binary to virt-designer - Add API for choosing network backend type - Add further test cases for validing domain builder - Always build test programs The libvirt-designer library builds on top of the libvirt-gconfig and libosinfo libraries, to provide an API that assists applications in building guest domain configurations based on libosinfo policy. The intention is that it be usable from applications such as virt-manager and GNOME boxes which currently duplicate this kind of policy based configuration logic between them. It is still at an early experimental stage of development so it is liable to have further ABI incompatible changes in future releases, which will require recompiling applications and possibly source level changes too. Thanks to all the people who contributed towards this new release.

[libvirt] [PATCH v2 0/3] unify memtune value representation in libvirt
by Pavel Hrdina 06 Mar '15

06 Mar '15

The first patch rewrites virsh memtune command to accept 0 as valid value instead of ignoring it. In the second patch I'll introduce a simple helper to crop the *_limit values to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED as its used several times while reading values from cgroups and also a helper to check whether the memory limits are set or not. The last patch actually changes the internal representation of unlimited memtune settings. More detailed description is in commit message. My motivation to change it completely is to prevent future bugs with those limits.

[libvirt] [PATCH v8 0/4] Introduce API to query IP addresses for given domain
by Nehal J Wani 06 Mar '15

06 Mar '15

This feature has been requested for a very long time. Since qemu guest agent and leaseshelper give us reliable results, now the wait is over. The RFC was first proposed by Michal Privoznik: http://www.redhat.com/archives/libvir-list/2012-February/msg00437.html A patch was submitted, using structs: https://www.redhat.com/archives/libvir-list/2012-June/msg00220.html Another patch was submitted, using XML: https://www.redhat.com/archives/libvir-list/2012-June/msg00904.html Neither of the patches were accepted, probably due to lack of extensibility and usability. Hence, we thought of using virTypedParameters for reporting list of interfaces along with their MAC address and IP addresses. The RFC can be found here: https://www.redhat.com/archives/libvir-list/2013-July/msg00084.html The idea of extensibility was rejected and rendered out of scope of libvirt. Hence, we were back to structs. This API is called virDomainInterfaceAddresses which returns a dynamically allocated array of virDomainInterface struct. The great disadvantage is once this gets released, it's written in stone and we cannot change or add an item into it. The virsh CLI supports two methods: * Return information (list of all associated interfaces with MAC address and IP addresses) of all of the domain interfaces by default (if no interface name is provided) * Return information for the specified interface (if an interface name is provided) v8: * qemuDomainInterfaceAddresses: redo logic related to flags * Make sure that NIC(s) on guest is/are using libvirt virtual network before querying leaseshelper * domifaddr: change --network option from VSH_OT_DATA to VSH_OT_STRING v7: * Enable support for DHCP lease file parsing method * http://www.redhat.com/archives/libvir-list/2014-December/msg00866.html v6: * Inclusion of flags, readonly check for guest agent connection * Correction of memory leaks, other small nits. * https://www.redhat.com/archives/libvir-list/2013-September/msg00350.html v5: * s/virDomainInterfacesAddresses/virDomainInterfaceAddresses. * Case for IP aliasing handled using virHashTable. * New test cases added, involving multiple and 0 IP addresse(s) per interface. * IP prefix changed from int to unsigned int. * Changes to practice libvirt habits. * https://www.redhat.com/archives/libvir-list/2013-September/msg00003.html v4: * Various style nits, indentation errors, memory leaks fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg01265.html v3: * Upper bounds to number of interfaces and addresses per interface introduced. * Change from array of structs to array of pointers * ifaces_count moved from function argument to return value * Changes in variable names * Test cases added for qemuAgentGetInterfaces. * https://www.redhat.com/archives/libvir-list/2013-August/msg01215.html v2: * Logical errors, memory leaks and few other errors fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg00631.html v1: * http://www.redhat.com/archives/libvir-list/2013-July/msg01553.html Nehal J Wani (4): domifaddr: Implement the public APIs domifaddr: Implement the remote protocol domifaddr: Implement the API for qemu domifaddr: Add virsh support daemon/remote.c | 134 ++++++++++++++++++++++++++ include/libvirt/libvirt-domain.h | 27 ++++++ src/driver-hypervisor.h | 5 + src/libvirt-domain.c | 129 +++++++++++++++++++++++++ src/libvirt_public.syms | 6 ++ src/qemu/qemu_agent.c | 202 +++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 4 + src/qemu/qemu_driver.c | 173 +++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 100 +++++++++++++++++++ src/remote/remote_protocol.x | 36 ++++++- src/remote_protocol-structs | 24 +++++ tests/qemuagenttest.c | 188 ++++++++++++++++++++++++++++++++++++ tools/virsh-domain-monitor.c | 141 +++++++++++++++++++++++++++ tools/virsh.pod | 16 ++++ 14 files changed, 1184 insertions(+), 1 deletion(-) -- 2.1.0
