[libvirt-tck] scripts: fix disk media change test
by Jim Fehlig 24 Mar '20

24 Mar '20

Since the introduction of the 'index' attribute of a disk's <source> element, test 207-disk-media-change.t is failing. The test is a bit flawed in that it compares initial and final domXML after changing the media of a cdrom disk device. The test only needs to check the final domXML to ensure the correct <source> path exists at the end of the test.

Propose to extend the capability of arm cpu driver
by Zhenyu Zheng 24 Mar '20

24 Mar '20

Hello Libvirt, With more and more ARM servers on the market and increasing amount of users, we got reported alot that Libvirt cannot provide as much function on ARM platform as on other platforms(mainly x86), some basic founctions are missing, such as showing cpu model details and features using ``virsh capabilities``, comparing cpus etc. So I would like to propose to extend the capability of ARM cpu driver. Since I'm quite new here, I searched through the mailing list and did not find much information on this, so I would like to know that will this be something that I could work on? BR, Zhenyu Zheng

TCK regression from blockdev change
by Jim Fehlig 24 Mar '20

24 Mar '20

Hi all, I noticed libvirt-tck test 207-disk-media-change.t is failing with 6.1.0, although I _think_ the failure has actually been around since the change to using blockdev in the qemu driver. The test essentially creates a minimal domain with a cdrom disk device, then calls attach_device a few times, changing the <source> of the disk. The last attach_device uses the same <source> as when the domain was created and expects the initial and final XML to be the same. For reference, here's a link to the test https://libvirt.org/git/?p=libvirt-tck.git;a=blob;f=scripts/domain/207-disk… However the test fails since the 'index' attribute of the <source> element is not the same between initial XML (index='1') and final XML (index='5'). Indeed with each attach operation the index is incremented. Should libvirt be fixed to always provide an index of 1 for this disk config? Or should we adjust the test case? I'm not so familiar with this functionality but I lean towards the former since attaching a disk with a missing source (no media) results in odd looking disk config <disk type='file' device='cdrom'> <driver name='qemu' type='raw' cache='none'/> <source index='4'/> <target dev='hdc' bus='ide'/> <readonly/> <alias name='ide0-1-0'/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> Regards, Jim

[PATCH v2 0/5] NVDIMM suport for pSeries guests
by Daniel Henrique Barboza 23 Mar '20

23 Mar '20

changes in v2, all of them affecting just pSeries guests: - added 'label' requirement - added code to align down the NVDIMM device previous version: https://www.redhat.com/archives/libvir-list/2020-March/msg00165.html This patch series adds NVDIMM suport for ppc64 guests, which consists on adding an extra 'uuid' element in the nvdimm command line and the target label size must always be provided in the memory definition. No changes were made in the existing NVDIMM support for x86 and other archs. Daniel Henrique Barboza (5): conf: Introduce optional 'uuid' element for NVDIMM memory formatdomain.html.in: document the new 'uuid' NVDIMM element conf, qemu: enable NVDIMM support for ppc64 formatdomain.html.in: document NVDIMM 'label' requirement for pSeries news.xml: document the new NVDIMM support for Pseries guests docs/formatdomain.html.in | 24 +++++++-- docs/news.xml | 11 ++++ docs/schemas/domaincommon.rng | 5 ++ src/conf/domain_conf.c | 44 ++++++++++++++-- src/conf/domain_conf.h | 3 ++ src/qemu/qemu_command.c | 7 +++ src/qemu/qemu_domain.c | 47 +++++++++++++++-- .../memory-hotplug-nvdimm-ppc64.args | 32 ++++++++++++ .../memory-hotplug-nvdimm-ppc64.xml | 50 +++++++++++++++++++ tests/qemuxml2argvtest.c | 4 ++ .../memory-hotplug-nvdimm-ppc64.xml | 50 +++++++++++++++++++ tests/qemuxml2xmltest.c | 2 + 12 files changed, 268 insertions(+), 11 deletions(-) create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-ppc64.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-ppc64.xml create mode 100644 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-ppc64.xml -- 2.24.1

Virtualbox Support for 6.x ?
by CDT CDT 23 Mar '20

23 Mar '20

Hello all, TL;DR: Is there any libvirt update regarding VBox 6.x planned until July 2020? I tried using libvirt 4.x / virsh with Virtualbox 6.1.4, which seem to not work. The output of virsh -V tells me that hypervisor should be able for that: Compiled with support for: Hypervisors: … VirtualBox … If I try to connect to a vbox session I get following error: error: failed to connect to the hypervisor error: internal error: unable to initialize VirtualBox driver API I already saw from different threads messages like this: libvirt version: 5.10.0 Libvirt doesn't support VirtualBox API version 6001000 regarding the libvirt changelog, only Virtualbox 5.2 is officially supported. Unfortunately, the support/maintenance for Virtualbox 5.2. ends in July 2020. Is there any libvirt update regarding VBox 6.x planned until July 2020? And is following combination in general possible: Libvirt + VBox + Windows Guest/VM ? Best regards Emanuel
