[Libvirt-announce] Entering freeze for libvirt-4.3.0
by Daniel Veillard 29 Apr '18

29 Apr '18

As planned I just tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems all fine with my limited testing and jenkins is all green: https://ci.centos.org/view/libvirt/ so so far thing looks good but that won't replace individual testing especially on other arches and OSes ! If thing go well I will push the RC2 over the week-end and target the final 4.3.0 release on Tues or Wed, in the meantime, plase give it some testing !

[Libvirt-announce] 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-announce] Entering freeze for libvirt-4.2.0
by Daniel Veillard 29 Mar '18

29 Mar '18

As planned I just tagged the RC1 in git and pushed the signed tarball and rpms at the usual place: ftp://libvirt.org/libvirt/ This seems fine with my minimal testing, and CI at https://ci.centos.org/view/libvirt/ looks pretty good (except libvirt-master-build, weird ...) so this should not be a problem but please give it some testing especially on other arches and platforms. If everything goes well, I will push rc2 on Thursday for a final release over the w.e., but please give it a try first ! thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[Libvirt-announce] ANNOUNCE: libvirt-dbus 0.0.1 released
by Pavel Hrdina 23 Mar '18

23 Mar '18

I'm happy to announce the release of libvirt-dbus 0.0.1. libvirt-dbus wraps libvirt API to provide high-level object-oriented API better suited for dbus-based applications. This is a first release which should be considered as unstable release since we don't promise API stability. You can download it here: https://libvirt.org/sources/dbus/libvirt-dbus-0.0.1.tar.gz This release contains a limited support of libvirt APIs as proof of concept, but we are planning to cover all relevant APIs. Thanks everybody who contributed! Pavel

[Libvirt-announce] Entering freeze for libvirt 4.1.0 release
by Daniel Veillard 28 Feb '18

28 Feb '18

I didn't sent a warning mail, but people reminded me that it's time to roll the releases, so I just tagged rc1 in git head and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Looks fine with my limited testing, amazingly https://ci.centos.org/view/libvirt/ is all green so things seems they should go smoothly, that said the devil is in the details so please give this RC1 some testing especially on other platforms and OSes ! It all goes well I will push rc2 on Wed and the final release early Fri, but in the meantime, please test it :-) thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[Libvirt-announce] Release of libvirt-4.0.0
by Daniel Veillard 19 Jan '18

19 Jan '18

First release of the year ! A bit late but it is now tagged in git and signed tarball and rpms are at the usual place: ftp://libvirt.org/libvirt/ I also pushed a release of the python bindings in git and at ftp://libvirt.org/libvirt/python/ This is a relatively small release, probably due to the end of year slowdown though there is some notable addition: * New features - tools: Provide bash completion support. Both virsh and virt-admin now implement basic bash completion support. - qemu: Refresh capabilities on host microcode update A microcode update can cause the CPUID bits to change; therefore, the capabilities cache should be rebuilt when such an update is detected on the host. - lxc: Set hostname based on container name * Improvements - CPU frequency reporting improvements The CPU frequency will now be reported by virsh nodeinfo and other tools for s390 hosts; at the same time; CPU frequency has been disabled on aarch64 hosts because there's no way to detect it reliably. - libxl: Mark domain0 as persistent - Xen: Add support for multiple IP addresses on interface devices - qemu: Add support for hot unplugging redirdev device * Bug fixes - qemu: Enforce vCPU hotplug granularity constraints QEMU 2.7 and newer don't allow guests to start unless the initial vCPUs count is a multiple of the vCPU hotplug granularity, so validate it and report an error if needed. thanks everybody for your help with this release, be it code, bug reports reviews, documentation, etc ... Enjoy the new release !

[Libvirt-announce] Entering freeze for libvirt-4.0.0
by Daniel Veillard 17 Jan '18

Hi all, as planned I just tagged the Release Candidate 1 in git for 4.0.0, I also pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ No issue found in my limited testing, weirdly the CI says master is red for 4 days but it build just fine here so there has to be something on jenkins: https://ci.centos.org/view/libvirt/ Please give it a try, I will likely push an RC2 end of Monday, and then we can have the final release around Wed if everything looks fine. Feedback on other architectures and OSes always welcome :-) thanks !

[Libvirt-announce] Release of libvirt-3.10.0
by Daniel Veillard 04 Dec '17

04 Dec '17

A little bit late but it's out, the new release is tagged in git and signed tarball and rpms have been pushed to the usual place: ftp://libvirt.org/libvirt/ I also pushed the corresponding release of python bindings at ftp://libvirt.org/libvirt/python/ This release brings a significant set of new features and noticeable improvements in addition to bug fixes: New features: - conf: Support defining distances between virtual NUMA cells A NUMA hardware architecture supports the notion of distances between NUMA cells. This can now be specified using the <distances> element within the NUMA cell configuration. Drivers which support this include Xen and QEMU. - Xen: Support defining vNUMA topology Xen now supports defining a virtual NUMA topology for VMs, including specifying distances between NUMA cells. - qemu: Add the ability to configure HPT resizing for pSeries guests The user can now decide whether HPT (Hash Page Table) resizing should be enabled, disabled or required instead of leaving it up to hypervisor defaults and negotiation between the guest and the host. - qemu: Add vmcoreinfo feature Starting with QEMU 2.11, the guest can save kernel debug details when this feature is enabled and the kernel supports it. It is useful to process kernel dump with KASLR enabled, and also provides various kernel details to crash tools. - conf: Move the auth and encryption definitions to disk source Allow parsing and formatting of the auth and encryption sub-elements to be a child of the source element. This will allow adding an auth sub-element to a backingStore or mirror elements as a means to track specific authentication and/or encryption needs. Improvements: - vbox: Add VirtualBox 5.2 support - vbox: Add support for configuring storage controllers The VirtualBox driver now supports the <controller> element in the domain XML for configuring storage controllers in VBOX VMs. Additionally, libvirt's domain XML schema was updated to allow optional model attribute for <controller type='ide'> which is used by the VBOX driver to set the IDE controller model to be one of 'piix4', 'piix4' (default), or 'ich6'. Finally, with this change dumpxml generates <controller> elements that correspond to current VBOX VM storage controller configuration. - vbox: Add support for attaching empty removable disks The VirutalBox driver now supports adding CD-ROM and floppy disk devices that do not have the disk source specified. Previously such devices were silently ignored. - vbox: Add support for attaching SAS storage controllers In VirtualBox, SCSI and SAS are distinct controller types whereas libvirt does not make such distinction. Therefore, the VBOX driver was updated to allow attaching SAS controllers via <controller type='scsi' model='lsisas1068'> element. If there are both SCSI and SAS controllers present in the VBOX VM, the domain XML can associate the disk device using the <address> element with the controller attribute, and optionally, set the port via unit attribute. - qemu: Generate predictable paths for qemu memory backends In some cases management applications need to know paths passed to memory-backend-file objects upfront. Libvirt now generates predictable paths so applications can prepare the files if they need to do so. - Shareable disks work properly with recent qemu Recent qemu versions added image locking to avoid potential corruption of disk images. This broke shareable disks with libvirt since the feature was turned on by default in qemu. Libvirt now enables sharing of those disks in qemu so that the image locking is not applied in that case. Additionally libvirt now checks that shareable disks have supported format (raw) to avoid metadata corruption. - Improve serial console behavior on non-x86 architectures ppc64, aarch64 and s390x guests were treating the <serial> and <console> elements differently from x86, in some cases presenting misleading information to the user. The behavior is now consistent across all architectures and the information reported is always accurate. Bug fixes: - vbox: Do not ignore failures to attach disk devices when defining The define now fails and reports an error if any of the controller or disk devices specified in the domain XML fail to attach to the VirtualBox VM. - vbox: Fix dumpxml to always output disk devices The VirtualBox driver was ignoring any disk devices in dumpxml output if there was a SAS storage controller attached to the VM. - vbox: Fix dumpxml to always generate valid domain XML When a VirtualBox VM has multiple disks attached, each to a different storage controller that uses 'sd' prefix for block device names e.g. one disk attached to SATA and one to SCSI controller, it no longer generates XML where both would have 'sda' device name assigned. Instead it properly assigns 'sda' and 'sdb' to those disks in the order of appearance. - Securely pass iSCSI authentication data Rather than supplying the authentication data as part of the iSCSI URL for a disk or host device, utilize the encrypted secret object to securely pass the authentication data. Thanks everybody for your help getting this release out, with ideas, patches, reviews, documentations, bug reports ... Enjoy this release, and please not that the next one (4.0.0) is scheduled for mid january !

As planned yesterday (but a bit late) I tagged Release Candidate 1 in git and pushed the signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work fine in my limited testing, but please give them a try especially for portability accross arches and platforms ! If things go well (and https://ci.centos.org/view/libvirt/ looks good !) then I will push RC2 on Fraiday and get the final 3.10.0 out on Monday, but please give it some testing and report ! thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/
