[libvirt] [PATCH] spec: Run all make jobs in parallel
by Andrea Bolognani 08 Nov '16

08 Nov '16

Commit e8861f69714f changed our spec file to compile and run tests in parallel. That's a very good step forward, but why stop there? Let's run *all* make jobs in parallel and really put those expensive cores to use! On my laptop, this shaves ~10s off 'make rpm'. --- libvirt.spec.in | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 5133936..a2c2f2f 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1210,9 +1210,9 @@ rm -fr %{buildroot} # Avoid using makeinstall macro as it changes prefixes rather than setting # DESTDIR.

[libvirt] [PATCH] Allow saving QEMU libvirt state to a pipe
by Roy Keene 08 Nov '16

08 Nov '16

All, Currently the "virsh save" command opens a file to save a domain's XML and memory state, does the save, and then re-opens the file to simulate seeking to the beginning to update the header to indicate that the file is complete. For pipes this is not possible, attempting to re-open the pipe will not connect you to the same consumer. Seeking is also not possible on a pipe. Attached is a patch that detects if the file being written to is not seekable, and if so writes the completed header initially, then writes the normal data, and avoids re-opening the file. This is useful to me for saving a VM state directly to Ceph RBD images without having an intermediate file. I've tested this patch successfully (against v1.3.5) for both saving and restoring a domain: # *( fifo="$(mktemp -u)"; mkfifo "${fifo}" && virsh save one-0 "${fifo}" & cat "${fifo}" | rbd import - rbd/test1234 & wait; rm -f "${fifo}" )* Domain one-0 saved to /tmp/tmp.HK4hChiQqB # # *( fifo="$(mktemp -u)"; mkfifo "${fifo}" && rbd export rbd/test1234 - > "${fifo}" & virsh restore "${fifo}" & wait; rm -f "${fifo}" ) * Exporting image: 100% complete...done.

[libvirt] qemu: domain notification for serial channel changes
by Matt Broadstone 08 Nov '16

08 Nov '16

Hi, I was in the process of implementing a custom qemu agent which communicates over virtio-serial channels, when I noticed that the only way to receive channel state change notifications was to poll the domstatus XML file. There does seem to be code in libvirt to monitor for serial change events (https://libvirt.org/git/?p=libvirt.git;a=blob;f=src/qemu/qemu_driver.c;h=38…) however it's hardcoded/specific to the qemu-ga (explicitly checking for ports named "org.qemu.guest_agent.0"). It occurs to me that while there was a class of events added for guest lifecycle changes, it might be a more generic solution to provide events for character device changes. Am I missing some existing functionality here? I'm a first-time poster here so I was hoping to both signal my intent to implement something more generic, as well as ping the community to see if there would be interest in this work or reasons why I shouldn't be doing this. Regards, Matt

[libvirt] [PATCH 00/17] Redo website layout and branding
by Daniel P. Berrange 07 Nov '16

07 Nov '16

The current libvirt website design dates from 2008 and has not changed significantly since. Compared to contemporary open source project websites it looks pretty dated and cluttered. This series incrementally changes the website to have a completely new layout and branding. Since the original adobe illustrator files are long since lost, this series introduces a newly created variant of the libvirt logo with Inkscape as an SVG file. The libvirt logo used a specific font with angled tops to letters like "l", "b" and "t" - this is the "Overpass" font, made available by Red Hat under an open source font license. The re-branding makes use of webfont support so that we can use this font across the entire libvirt website for a consistent look. The colors of the website CSS now exactly match the colors used in the logo in most places. The bigger change is in the layout, with the huge left hand sitemap nav bar being removed to give more space to the main content. The front page now directly links to the key pages that were shown to be highly visited in the apache web logs. Most of the rest of the links are now available from the "docs.html" page linked from "Learn" in the top nav bar. Another key change is that the download page now covers all language bindings, test suites, docs released by the project, not merely the core C library. Finally a new page "contribute.html" is added as the source of information useful to people wishing to get involved in the libvirt project. View the new site here https://berrange.fedorapeople.org/libvirt-new-website/ Note that the front page includes a feed of 4 most recent blog posts, however, if visiting over https:// this will be blocked by browsers. In firefox you can tell it to allow http:// content temporarily at which point the feed will appear. I'll be doing a proper fix by getting a TLS cert for virt-tools.org website setup. Daniel P.

[libvirt] [RFC 0/5] Qemu: s390: Cpu Model Support
by Jason J. Herne 05 Nov '16

05 Nov '16

Thanks for all your feedback up to this point. We've made some progress on this and we also have a few questions. Please let us know if we're on the right track or if we're off in the weeds on this. Here is what we have so far. Patch #1 updates s390's cpu driver to support some operations needed for cpu model support within Libvirt's existing infrastructure. Patch #2 removes s390's hard coded "host" model string. Jiri thought it made more sense to simply leave this blank. Path #3 adds qmp query-cpu-model-expansion command. Patch #4 probes Qemu's view of the host model (query-cpu-model-expansion), caches the response and uses it to fill in qemuCaps->hostCpuModel. Archs that do not implement query-cpu-model-expansion will continue to fill in qemuCaps->hostCpuModel from caps->host.cpu. Patch #5 updates qemuBuildCpuModelArgStr's VIR_CPU_MODE_HOST_MODEL case. It seems like all archs except PPC64 do not support host model mode. We add an s390 path here and get the guest cpu model from virQEMUCapsGetHostModel() which will get the model name from qemuCaps->hostCpuModel. NOTE: I just realized we'll need need to handle the case where virQEMUCapsGetHostModel returns NULL or the model is NULL or "". We probably should just throw an error and give up in that case. Here is a list of outstanding things to do and some questions. 1. virsh domcapabilities --emulatorbin flag This works today if the command is passed --emulatorbin /usr/bin/qemu-kvm. If no emulatorbin is given then Libvirt seems to choose /usr/bin/qemu-system-s390x my system which does not have kvm enabled. A kvm session is needed for s390 to properly compute the host model. A kvm session is only available for the qemu-kvm binary. Is the answer to tell our users to always supply --emulatorbin with /usr/bin/qemu-kvm argument? Or is there a more user friendly solution to this? 2. virsh baseline and compare support. Both of these commands, for s390 at least, will need to spin up a Qemu session with monitor to compute the result. The only place I see this done today is qemu_capabilities. Rather than blindly duplicate the code, I guess we should carve out some type of api for spinning up a monitor backed Qemu instance, yes? Also, neither compare nor baseline have the --emulatorbin flag. So we'll either need to add them or find an alternate solution. Any thoughts on this? 3.Support host passthrough mode. This essentially just means passing -cpu host to qemu. We know Qemu supports this for s390 today. But Libvirt claims it is not supported due to the following: In virQEMUCapsIsCPUModeSupported, our virt "type" is VIR_DOMAIN_VIRT_QEMU, and not VIR_DOMAIN_VIRT_KVM. virttype comes from domCaps and is set here: qemuConnectGetDomainCapabilities() The relevant code is: if (qemuHostdevHostSupportsPassthroughLegacy() || qemuHostdevHostSupportsPassthroughVFIO()) virttype = VIR_DOMAIN_VIRT_KVM; else virttype = VIR_DOMAIN_VIRT_QEMU; I'll admit, I have not been able to figure out why these checks are failing in my test environment, when I suspect they should be passing. But in my case it seems as though these relate to host device passthrough. How do they apply to cpu model passthrough. What am I missing? Thanks for your time. Collin L.

05 Nov '16

I am pleased to announce that a new release of the libvirt-glib package, version 1.0.0, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) Changes in this release: - Switch to new release numbering scheme, major digit incremented each year, minor for each release, micro for stable branches (if any) - Fix Libs.private variable in pkg-config file - Fix git introspection warnings - Add ability to set SPICE gl property - Add support for virtio video model - Add support for 3d accel property - Add support for querying video model - Add support for host device config for PCI devs - Add docs for more APIs - Avoid unused variable warnings - Fix check for libvirt optional features to use pkg-config - Delete manually written python binding. All apps should use PyGObject with gobjection introspection. - Add schema to be NULL on config objects - Preserve unknown devices listed in XML - Add further test coverage libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not currently guaranteeing that libvirt-glib libraries are permanently API/ABI stable. That said we do not expect to break the API/ABI for the forseeable future and will always strive avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.
