[libvirt] [RFC v2 2/3] nvdimm: update qemu command-line generating for NVDIMM memory
by Luyao Zhong 30 Nov '18

30 Nov '18

According to the result parsing from xml, add corresponding properties into QEMU command line, including 'align', 'pmem', 'unarmed' and 'nvdimm-persistence'.

[libvirt] Entering freeze for libvirt-4.10.0
by Daniel Veillard 30 Nov '18

30 Nov '18

As planned I just tagged the RC1 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, https://ci.centos.org/view/libvirt/ seems mostly green so far things looks good, but as usual we need more testing especially on other OSes and architectures. If everything goes fine, I will push the RC2 on Thursday for a final release over the week-end or next Monday. In the meantime please give it some testing ! 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] [PATCH v2 00/13] Autoselect a DRM node for egl-headless and add it to cmdline
by Erik Skultety 29 Nov '18

29 Nov '18

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1628892. The problem is that we didn't put the DRI device into the namespace for QEMU to access, but that was only a part of the issue. The other part of the issue is that QEMU doesn't support specifying 'rendernode' for egl-headless yet (patches are already merged upstream for 3.1) Instead, QEMU's been autoselecting the DRI device on its own. There's no compelling reason for libvirt not doing that instead and thus prevent any permission-related issues.

[libvirt] [PATCH for-4.0 v3 0/2] virtio: Provide version-specific variants of virtio PCI devices
by Eduardo Habkost 29 Nov '18

29 Nov '18

Existing modern-only device types are not being touched by v3, as they don't need separate variants. However, I plan to implement separate cleanups in the code that calls virtio_pci_force_virtio_1(), first, and then propose additional changes (e.g. deprecating disable-legacy and disable-modern in those device types). Changes v2 -> v3: * Split into two separate patches (type registration helper and introduction of new types) * Rewrote virtio_pci_types_register() completely: * Replaced magic generation of type names with explicit fields in VirtioPCIDeviceTypeInfo * Removed modern_only field (not necessary anymore) * Don't register a separate base type unless necessary Changes v1 -> v2: * Removed *-0.9 devices. Nobody will want to use them, if transitional devices work with legacy drivers (Gerd Hoffmann, Michael S. Tsirkin) * Drop virtio version from name: rename -1.0-transitional to -transitional (Michael S. Tsirkin) * Renamed -1.0 to -non-transitional * Don't add any extra variants to modern-only device types (they don't need it) * Fix typo on TYPE_VIRTIO_INPUT_HOST_PCI (crash reported by Cornelia Huck) * No need to change cast macros for modern-only devices * Rename virtio_register_types() to virtio_pci_types_register() Original patch description: Many of the current virtio-*-pci device types actually represent 3 different types of devices: * virtio 1.0 non-transitional devices * virtio 1.0 transitional devices * virtio 0.9 ("legacy device" in virtio 1.0 terminology) That would be just an annoyance if it didn't break our device/bus compatibility QMP interfaces. With this multi-purpose device type, there's no way to tell management software that transitional devices and legacy devices require a Conventional PCI bus. The multi-purpose device types would also prevent us from telling management software what's the PCI vendor/device ID for them, because their PCI IDs change at runtime depending on the bus where they were plugged. This patch adds separate device types for each of those virtio device flavors: * virtio-*-pci: the existing multi-purpose device types * virtio-*-pci-transitional: virtio-1.0 device supporting legacy drivers * virtio-*-pci-non-transitional: modern-only Reference to previous discussion that originated this idea: https://www.mail-archive.com/qemu-devel@nongnu.org/msg558389.html Eduardo Habkost (2): virtio: Helper for registering virtio device types virtio: Provide version-specific variants of virtio PCI devices hw/virtio/virtio-pci.h | 78 +++++++-- hw/display/virtio-gpu-pci.c | 7 +- hw/display/virtio-vga.c | 7 +- hw/virtio/virtio-crypto-pci.c | 7 +- hw/virtio/virtio-pci.c | 267 ++++++++++++++++++++++------- tests/acceptance/virtio_version.py | 177 +++++++++++++++++++ 6 files changed, 453 insertions(+), 90 deletions(-) create mode 100644 tests/acceptance/virtio_version.py -- 2.18.0.rc1.1.g3f1ff2140

[libvirt] [PATCH] virsh: Strip XML declaration when extracting CPU XMLs
by Jiri Denemark 29 Nov '18

29 Nov '18

Since commit v4.3.0-336-gc84726fbdd all {hypervisor-,}cpu-{baseline,compare} commands use a generic vshExtractCPUDefXMLs helper for extracting individual CPU definitions from the provided input file. The helper wraps the input file in a <container> element so that several independent elements can be easily parsed from the file. This works fine except when the file starts with XML declaration (<?xml version="1.0" ... ?>) because the XML declaration cannot be put inside any element. In fact it has to be at the very beginning of the XML document without any preceding white space characters. We can just simply skip the XML declaration. https://bugzilla.redhat.com/show_bug.cgi?id=1595993 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- tools/virsh-host.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/tools/virsh-host.c b/tools/virsh-host.c index 16f504bafe..b7f86bdd91 100644 --- a/tools/virsh-host.c +++ b/tools/virsh-host.c @@ -1130,13 +1130,20 @@ vshExtractCPUDefXMLs(vshControl *ctl, xmlDocPtr xml = NULL; xmlXPathContextPtr ctxt = NULL; xmlNodePtr *nodes = NULL; + char *doc; size_t i; int n; if (virFileReadAll(xmlFile, VSH_MAX_XML_FILE, &buffer) < 0) goto error; - if (virAsprintf(&xmlStr, "<container>%s</container>", buffer) < 0) + /* Strip possible XML declaration */ + if (STRPREFIX(buffer, "<?xml") && (doc = strstr(buffer, "?>"))) + doc += 2; + else + doc = buffer; + + if (virAsprintf(&xmlStr, "<container>%s</container>", doc) < 0) goto error; if (!(xml = virXMLParseStringCtxt(xmlStr, xmlFile, &ctxt))) -- 2.19.1

This serie fixes a bug related to IPv{4,6} gateway settings when it is defined and used with multiple network definitions. Basically, this data is being carried on to the next network settings because the pointer is not being cleaned up/initialized properly. This serie add a new test case to cover this scenario too. It will be so important to network index implemented on LXC 3.X. v1-v2: Fixing tabs inside the code.

[libvirt] [RFC v2 1/3] nvdimm: introduce more config elements into xml for NVDIMM memory
by Luyao Zhong 28 Nov '18

28 Nov '18

1.alignsize The 'alignsize' option allows users to specify the proper alignment. 2.pmem The 'pmem' option allows users to specify whether the backend storage of memory-backend-file is a real persistent memory. 3.persistence The 'persistence' option allows users to set guest platform supported features. It has two values, 'mem-ctrl' and 'cpu'. 4.unarmed The 'unarmed' option allows users to mark vNVDIMM read-only. These options can be configured respectively or simultaneously in domain xml file, here is an example: <devices> ... <memory model='nvdimm' access='shared'> <source> <path>/dev/dax0.0</path> <alignsize unit='MiB'>2</alignsize> <pmem/> </source> <target> <size unit='MiB'>4094</size> <node>0</node> <label> <size unit='MiB'>2</size> </label> <persistence>cpu</persistence> <unarmed/>
