* Implemented Suspend and Resume APIs. * Reused virsh functions for taking the Event Strings names from ENUM. * Merged all Domain Lifecycle events signals into one signal. Changed from v2: * Coding style issues. * Removed the Domain prefix for domain event type only in last patch. Katerina Koukiou (5): Implement Suspend method for Domain interface.

[libvirt] [PATCH] lxc: Use virDomainObjEndAPI after FindByName
by John Ferlan 02 Apr '18

For consistency, rather than open coding the Unref and Unlock, just use the virDomainObjEndAPI API.

[libvirt] [PATCH 0/4] vmx: allow more than 4 NICs (RHBZ#1560917)
by Pino Toscano 01 Apr '18

01 Apr '18

Hi, the VMX parser, used in the esx driver, has currently hardcoded 4 NICs possible, ignoring extra more than that. The following series removes this limitation, allowing to parse all the 10 NICs in the VMX of RHBZ#1560917. Thanks, Pino Toscano (4): vmx: check for present/enabled devices earlier vmx: allocate space for network interfaces if needed internal: add STRCASEPREFIX vmx: convert any amount of NICs src/internal.h | 1 + src/vmx/vmx.c | 150 +++++++++++----------- tests/vmx2xmldata/vmx2xml-esx-in-the-wild-8.vmx | 163 ++++++++++++++++++++++++ tests/vmx2xmldata/vmx2xml-esx-in-the-wild-8.xml | 89 +++++++++++++ tests/vmx2xmltest.c | 1 + 5 files changed, 325 insertions(+), 79 deletions(-) create mode 100644 tests/vmx2xmldata/vmx2xml-esx-in-the-wild-8.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-esx-in-the-wild-8.xml -- 2.14.3

[libvirt] Release of libvirt-4.2.0
by Daniel Veillard 01 Apr '18

01 Apr '18

Not April fool one, I made the release on time :-) It's signed in git and signed tarball and rpms are pushed to the usual place: ftp://libvirt.org/libvirt/ I also pushed a python binding 4.2.0 release which can be found at: ftp://libvirt.org/libvirt/python/ New features - Support building with Python 3 Python is required to build libvirt, and up until now only Python 2 could be used as an interpreter. All scripts used during build have now been made compatible with Python 3, which means both major releases of the language are fully supported. - qemu: Provide ccw address support for graphics and input devices Support the virtio-gpu-ccw device as a video device and virtio-{keyboard, mouse, tablet}-ccw devices as input devices on S390. Improvements - qemu: Add logging of guest crash information on S390 On S390, when the guest crashes and QEMU exposes the guest crash information, log the relevant data to the domain log file. - qemu: use arp table of host to get the IP address of guests Find IP address of a VM by arp table on hosts. If someone customizing IP address inside VM, it will be helpful. - Xen: Remove hard-coded scheduler weight The libxl driver was accidentally hard-coding the per-domain scheduler weight to 1000, silently ignoring any user-provided <shares> in <cputune>. The driver now honors <shares>, and defers setting a default value to Xen. Note that the Xen default is 256, so any domains started after this improvement will have one fourth the shares of previously started domains. If all domains must have equal CPU shares, administrators must manually set the weight of previously started domains to 256, or restart them. there is no documented bug fix but there is quite a few there too :-) Thanks everybody for your help getting this release, with patches, reviews, bug reports, documentation, etc. Enjoy !

[libvirt] [PATCH] qemu: Randomly deny starting domains
