[libvirt] [PATCH for-QEMU-4.1] Declare -realtime as deprecated
by Thomas Huth 15 Apr '19

15 Apr '19

The old -realtime mlock=on|off parameter does exactly the same as the new -overcommit mem-lock=on|off parameter. Additionally, "-realtime" does not activate any additional "realtime" capabilities as the name might indicate. We should avoid to confuse the users this way, so let's deprecate the old -realtime option.

[libvirt] [PATCH 00/36] CPU driver enhancements and MSR features
by Jiri Denemark 15 Apr '19

15 Apr '19

In addition to usual CPUID bits, some CPU features started to be reported in IA32_ARCH_CAPABILITIES MSR. This series adds support for such CPU features. However, the last patch which actually adds definitions for some MSR features to the cpu_map should not be pushed yet as the QEMU interface for MSR features is not complete yet. If a domain with some MSR features enabled would be started, all of them would be marked as disabled in the live domain configuration (even though they were actually enabled by QEMU) and they would disappear during migration.

[libvirt] [PATCH] network: only reload firewall after firewalld is finished restarting
by Laine Stump 12 Apr '19

12 Apr '19

The network driver used to reload the firewall rules whenever a dbus NameOwnerChanged message for org.fedoraproject.FirewallD1 was received. Presumably at some point in the past this was successful at reloading our rules after a firewalld restart. Recently though I noticed that once firewalld was restarted, libvirt's logs would get this message: The name org.fedoraproject.FirewallD1 was not provided by any .service files After this point, no networks could be started until libvirtd itself was restarted. The problem is that the NameOwnerChanged message is sent twice during a firewalld restart - once when the old firewalld is stopped, and again when the new firewalld is started. If we try to reload at the point the old firewalld is stopped, none of the firewalld dbus calls will succeed. The solution is to check the new_owner field of the message - we should reload our firewall rules only if new_owner is non-empty (it is set to "" when firewalld is stopped, and some sort of epoch number when it is again started).

[libvirt] [PATCH] network: clear cached error if we successfully create firewall chains

This commit failed to account for fact that we may invoke networkPreReloadFirewallRules() many times while libvirtd is running. For example when firewalld is restarted. When this happens the original failure may no longer occurr and we'll successfully create our top level chains. We failed to clear the cached error resulting in us failing to start virtual networks.

[libvirt] [PATCH] qemu: Label uniqDir when probing capabilities
by Martin Kletzander 12 Apr '19

12 Apr '19

This does not cause a problem in usual scenarios thanks to us allowing CAP_DAC_OVERRIDE for the qemu process, however in some scenarios this might be an issue because the directory is created with mkdtemp(3) which explicitly creates that with 0700 permissions and qemu running as non-root cannot access that. The scenarios include: - Builds without CAPNG - Running libvirtd in a container [1] - and possibly others.

[libvirt] [PATCH v2] maint: Add filetype annotations to Makefile.inc.am
by Andrea Bolognani 12 Apr '19

12 Apr '19

Vim has trouble figuring out the filetype automatically because the name doesn't follow existing conventions; annotations like the ones we already have in Makefile.ci help it out. Signed-off-by: Andrea Bolognani <abologna(a)redhat.com> --- Changes from [v1]: * drop emacs annotation; * switch from filetype=make to filetype=automake.

[libvirt] RFC: remove qemu commandline parsing?
by Cole Robinson 12 Apr '19

12 Apr '19

qemu/qemu_parse_command.c powers 'sudo virsh domxml-from-native qemu-argv', parsing a qemu command line and attempting to turn it into libvirt domain XML. Some history: RFE: https://www.redhat.com/archives/libvir-list/2009-April/msg00266.html Patches: https://www.redhat.com/archives/libvir-list/2009-May/msg00321.html danpb blog post about related qemu-attach: https://www.berrange.com/posts/2011/07/13/attaching-libvirt-to-an-externall… At the time it was added, the parser was pretty comprehensive WRT to what libvirt XML features were available at the time. However it's quite hopelessly out of date these days and has been for a long time. As an example, the only -device it knows to parse is virtio-balloon, and it doesn't know anything about -netdev. So the parser can really only handle typical old style qemu options. AFAICT The original motivation for adding this and qemu-attach was providing a more straightforward path for direct qemu users to switch to libvirt. Googling does provide some cases of users successfully converting very simple qemu invocations to libvirt XML. But at least from my experience I don't think these features every really moved the needle in this respect. If anything, it's been that managing qemu has only grown more complex over time, which has made libvirt and tools that use it all the more compelling over launching your own qemu command line (for end users, think manually setting up usb2 with qemu directly). But IMO all that is kind of beside the point. I don't think it's debatable that the code is largely unused, and it hasn't seen many material improvements in the last 5 years, with zero plans to improve it on the horizon. It's 2000+ lines of text processing code living in every libvirtd instance. Deleting it all and making the qemu_driver.c APIs just return errors seems like an easy win considering we are trying to make libvirtd more modular and have a smaller footprint to facilitate usecases like kubevirt Thoughts? - Cole

[libvirt] [PATCH] lib: Don't use virReportSystemError() if virCommandRun() fails
by Michal Privoznik 12 Apr '19

12 Apr '19

Firstly, virCommandRun() does report an error on failure (which in most cases is more accurate than what we overwrite it with). Secondly, usually errno is not set (or gets overwritten in the cleanup code) which makes virReportSystemError() report useless error messages. Drop all virReportSystemError() calls in cases like this (I've found three occurrences).

[libvirt] [PATCH 0/7] vbox: drop support for many old versions
by Daniel P. Berrangé 12 Apr '19

12 Apr '19

Per this link: https://www.virtualbox.org/wiki/Download_Old_Builds VirtualBox 6.0 (active maintenance) VirtualBox 5.2 (active maintenance) VirtualBox 5.1 (no longer supported, support ended 2018/04) VirtualBox 5.0 (no longer supported, support ended 2017/05) VirtualBox 4.3 (no longer supported, support ended 2015/12) VirtualBox 4.2 (no longer supported, support ended 2015/12) VirtualBox 4.1 (no longer supported, support ended 2015/12) VirtualBox 4.0 (no longer supported, support ended 2015/12) We can certainly drop all the 4.x versions. The host OS those are officially supported on are very outdated: eg https://www.virtualbox.org/wiki/Download_Old_Builds_4_3 Linux Hosts: Ubuntu 13.04 ("Raring") / 13.10 ("Saucy") / 14.04 ("Trusty") / 14.10 ("Utopic") i386 | AMD64 Ubuntu 12.10 ("Quantal") i386 | AMD64 Ubuntu 12.04 ("Precise") i386 | AMD64 Ubuntu 10.04 LTS ("Lucid") i386 | AMD64 Debian 7 ("Wheezy") i386 | AMD64 Debian 6 ("Squeeze") i386 | AMD64 openSUSE 12.3 / 13.1 i386 | AMD64 openSUSE 11.4 / 12.1 / 12.2 i386 | AMD64 SUSE Linux Enterprise Server 11 (SLES11) i386 | AMD64 SUSE Linux Enterprise Server 10 (SLES10) i386 | AMD64 Fedora 18 ("Spherical Cow") / Fedora 19 ("Schrödingers Cat") i386 | AMD64 Fedora 17 ("Beefy Miracle") i386 | AMD64 Mandriva 2011.0 i386 | AMD64 Oracle Linux 6 ("OL6") / Red Hat Enterprise Linux 6 ("RHEL6") / CentOS 6 i386 | AMD64 Oracle Linux 5 ("OL5") / Red Hat Enterprise Linux 5 ("RHEL5") / CentOS 5 i386 | AMD64 All distributions i386 | AMD64 Although the catch all "All distributions" suggest it might work with newer distros, they are clearly a second tier from a support POV. All these explicitly targetted distros are outside libvirt's support policy. There is a question as to whether to delete 5.0 and 5.1 support from libvirt. There are no remainining #ifdef VBOX_API_VERSION conditionals in the vbox_tmpl.h file related to code differences between 5.0, 5.1 and 5.2, so keeping them is not a maint burden in code. The main burden is distributing the large vbox_CAPI_v5_0.h and vbox_CAPI_v5_1.h files which are ~1 MB in size (uncompressed) or ~85 kb (xz compressed). IOW versions 5.0 and 5.1 increase the release tarballs by a small amount, but nothing that is too unreasonable vs the overall size of 14 MB for libvirt source. Thus I have kept 5.0 and 5.1 support. VirtualBox 6.0 came out in Dec 2018 and given past practice it would not suprise me if that has API changes impacting libvirt. So some interested party might want to look at supporting that in libvirt. Daniel P.

[libvirt] [PATCH v3 0/7] extend virsh domstate to show additional information
by Bjoern Walk 12 Apr '19

12 Apr '19

This patch series introduces the ability to save additional information for the domain state and exposes this information in virsh domstate. For example in the case of QEMU guest panic events, we can provide additional information like the crash reason or register state of the domain. This information usually gets logged in the domain log but for debugging it is useful to have it accessible from the client. Therefore, let's introduce a new public API function, virDomainGetStateParams, an extensible version of virDomainGetState, which returns the complete state of the domain, including newly introduced additional information. Let's also extend virsh domstate and introduce a new parameter --info to show the domain state, reason and additional information when available. virsh # domstate --info guest-1 crashed (panicked) s390.core = 0 s390.psw-mask = 0x0002000180000000 s390.psw-addr = 0x000000000010f146 s390.reason = disabled-wait v2 -> v3: * try to find a reasonable naming-scheme for parameters * make state/reason in virDomainGetStateParams optional * use new API only when requested * print additional information per line for easier consumption v1 -> v2: * refactored the public API according to discussions to provide a more machine-parsable interface Bjoern Walk (7): qemu: monitor: move event data structure to domain qemu: domain: store and update panic info lib: introduce virDomainGetStateParams function remote: implement remoteDomainGetStateParams qemu: implement qemuDomainGetStateParams virsh: domstate: report detailed state if available news: add entry for virDomainGetStateParams docs/news.xml | 11 +++ include/libvirt/libvirt-domain.h | 76 +++++++++++++++++ src/driver-hypervisor.h | 9 ++ src/libvirt-domain.c | 62 ++++++++++++++ src/libvirt_public.syms | 5 ++ src/qemu/qemu_domain.c | 80 +++++++++++++++++- src/qemu/qemu_domain.h | 47 +++++++++++ src/qemu/qemu_driver.c | 126 +++++++++++++++++++++++++++- src/qemu/qemu_monitor.c | 53 +----------- src/qemu/qemu_monitor.h | 48 ++--------- src/qemu/qemu_monitor_json.c | 20 ++--- src/qemu/qemu_process.c | 2 +- src/remote/remote_daemon_dispatch.c | 50 +++++++++++ src/remote/remote_driver.c | 48 +++++++++++ src/remote/remote_protocol.x | 22 ++++- src/remote_protocol-structs | 13 +++ tools/virsh-domain-monitor.c | 94 +++++++++++++++++++-- tools/virsh.pod | 5 +- 18 files changed, 651 insertions(+), 120 deletions(-) -- 2.19.1

[libvirt] [PATCH v5] tests: perform cross compiler builds on GitLab CI
by Daniel P. Berrangé 12 Apr '19

GitLab CI provides some shared build runners that use Docker containers.

[libvirt] [PATCH 0/4] Add 'label' arg to VIR_ENUM_IMPL
by Cole Robinson 11 Apr '19

11 Apr '19

This is a different take on an RFE I posted in July: https://www.redhat.com/archives/libvir-list/2018-July/msg01815.html The goal of this series is to get us close to being able to raise errors from ToString and FromString functions directly. This will allow us to drop many hundreds of lines of error reporting and accompanying translator load. The first attempt above added a new macro, VIR_ENUM_IMPL_LABEL, which would take a string label, like 'domain type' for virDomainType enum. The generated ToString and FromString functions for that enum would now raise errors containing the label. Redundant error reporting could now be stripped out piece by piece as individual enums are converted. Thinking some more though I don't really like this strategy. Calling code won't have an easy way to know whether ToString/FromString functions are the type that raise errors or not, which could lead to new code accidentally omitting them and failing to raise an error. It could also stretch out the time that the code base is in a half transitioned state. This series is a slightly different direction. VIR_ENUM_IMPL now always takes a label, but for now we don't actually raise any errors. Later at a chosen time we can enable error reporting in the code and begin removing duplicate error reporting. The only downside is that until the transition is complete, there may be cases of double error reporting, but that's the lesser of two evils compared to the previous approach IMO. So the feedback I'm looking for: - Is this worth doing? (danpb+mprivozn said as much for first posting) - Is this approach acceptable? - Review of the strings added in the last patch Notes: - This is on top of pkrempa's virenum.c patches on list - The last two patches are separated to make review easier, but they will be committed together - When enabled, one notable case this will make error reporting worse is virTristate usage. But I think if we manually implement *TOString/FromString wrappers in that case we can require callers to pass in an identifying string. Something to think about for later Cole Robinson (4): Always put _LAST enums on second line of VIR_ENUM_IMPL cfg.mk: Only force _LAST enum on VIR_ENUM_IMPL second line util: Add 'label' field to VIR_ENUM_IMPL Add string labels to all VIR_ENUM_IMPL calls cfg.mk | 6 +- docs/apibuild.py | 12 ++ src/access/viraccessperm.c | 20 +- src/conf/capabilities.c | 3 +- src/conf/cpu_conf.c | 21 +- src/conf/device_conf.c | 3 +- src/conf/domain_capabilities.c | 3 +- src/conf/domain_conf.c | 333 +++++++++++++++++++----------- src/conf/interface_conf.c | 2 +- src/conf/netdev_vlan_conf.c | 3 +- src/conf/network_conf.c | 11 +- src/conf/node_device_conf.c | 12 +- src/conf/numa_conf.c | 7 +- src/conf/nwfilter_conf.c | 21 +- src/conf/snapshot_conf.c | 6 +- src/conf/storage_adapter_conf.c | 2 +- src/conf/storage_conf.c | 18 +- src/libxl/libxl_domain.c | 3 +- src/locking/lock_daemon.c | 3 +- src/logging/log_daemon.c | 3 +- src/lxc/lxc_domain.c | 7 +- src/lxc/lxc_native.c | 3 +- src/network/leaseshelper.c | 3 +- src/qemu/qemu_agent.c | 4 +- src/qemu/qemu_capabilities.c | 3 +- src/qemu/qemu_command.c | 27 ++- src/qemu/qemu_domain.c | 12 +- src/qemu/qemu_driver.c | 6 +- src/qemu/qemu_firmware.c | 6 +- src/qemu/qemu_migration.c | 3 +- src/qemu/qemu_migration_cookie.c | 2 +- src/qemu/qemu_migration_params.c | 9 +- src/qemu/qemu_monitor.c | 8 +- src/qemu/qemu_monitor_json.c | 10 +- src/remote/remote_daemon.c | 3 +- src/util/vircgroup.c | 3 +- src/util/vircgroupbackend.c | 3 +- src/util/vircgroupv1.c | 3 +- src/util/vircgroupv2.c | 3 +- src/util/virconf.c | 3 +- src/util/virenum.c | 28 ++- src/util/virenum.h | 15 +- src/util/virerror.c | 3 +- src/util/virfirewall.c | 3 +- src/util/virfirewalld.c | 6 +- src/util/virgic.c | 3 +- src/util/virhook.c | 20 +- src/util/virkeycode.c | 3 +- src/util/virlog.c | 3 +- src/util/virmdev.c | 3 +- src/util/virnetdev.c | 6 +- src/util/virnetdevmacvlan.c | 3 +- src/util/virnetdevvportprofile.c | 6 +- src/util/virpci.c | 9 +- src/util/virperf.c | 3 +- src/util/virprocess.c | 3 +- src/util/virresctrl.c | 12 +- src/util/virsecret.c | 3 +- src/util/virstorageencryption.c | 4 +- src/util/virstoragefile.c | 17 +- src/util/virsysinfo.c | 3 +- src/util/virtypedparam.c | 3 +- src/util/virutil.c | 1 - src/vmware/vmware_conf.c | 3 +- src/vmx/vmx.c | 3 +- tests/group-qemu-caps.pl | 2 +- tests/virkeycodetest.c | 3 +- tools/virsh-domain-monitor.c | 24 +-- tools/virsh-domain.c | 56 ++--- tools/virsh-host.c | 3 +- tools/virsh-network.c | 10 +- tools/virsh-nodedev.c | 2 +- tools/virsh-pool.c | 4 +- tools/virsh-secret.c | 2 +- tools/virsh-volume.c | 5 +- tools/virt-admin.c | 2 +- tools/virt-host-validate-common.c | 3 +- 77 files changed, 561 insertions(+), 334 deletions(-) -- 2.21.0

[libvirt] [PATCH] build: set --without-firewalld-zone in configure commandline for Fedora 30
by Laine Stump 11 Apr '19

11 Apr '19

The firewalld package in Fedora 30 didn't get support for rich rule priorities, which is required by the libvirt zonefile that's installed when the build is configured with --with-firewalld-zone, so we need to set --without-firewalld-zone for that version of Fedora. The needed feature is already upstream in firewalld, so it just needs another upstream release to be there. Let's be optimistic and assume that will happen prior to F31.

[libvirt] [PATCH v4 0/7] Facilitate running libvirt builds via docker containers
by Daniel P. Berrangé 11 Apr '19

11 Apr '19

For a while QEMU has provided simple make rules for building QEMU inside standard docker container environments. This provides an equivalent mechanism for libvirt inspired by QEMU's. QEMU actually builds the container images on developer's machines locally. Libvirt already hosts pre-built images on quay.io, so that is used directly as it is quicker to download them than to build them locally. This also ensures the container contents match what the live CI system is using, as opposed to building an image with newer packages. Changed in v4: - Re-add cross-compilation patches now that containers exist - Add CI_ prefix on all variables to avoid clashing with automake defined variables - Fix path given to -f arg for ci-check target - Remove dead code - Fix check for submodule checkout existing - Ensure macOS Homebrew is updated Changed in v3: - Lots of new variables & variable renames - Rename to top level Makefile.ci - Rename make targets to have @ separator for the image - Refactor macOS travis config Changed in v2: - Drop cross-compilation patches temporarily. The cross-compiler images are not yet built on quay.io and rather than creating and bulding many more images manually, I'm working on script to automate setup of quay.io images - Many changes to the make rules to make it possible to use them from Travis CI to match its currently testing setup - Modify Travis CI config to use the new make rules for consistency Daniel P. Berrangé (7): tests: add targets for building libvirt inside Docker containers travis: convert Ubuntu, CentOS & MinGW builds to use new make rules travis: use declarative syntax for Homebrew packages travis: remove display of test-suite.log from macOS travis: put macOS script inline in the macOS matrix entry tests: add cross compiler images to CI test help output tests: perform cross compiler builds on GitLab CI .gitignore | 1 + .gitlab-ci.yml | 74 +++++++++++++++++ .travis.yml | 78 +++++------------ Makefile.am | 2 + Makefile.ci | 222 +++++++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 321 insertions(+), 56 deletions(-) create mode 100644 .gitlab-ci.yml create mode 100644 Makefile.ci -- 2.20.1

[libvirt] [PATCH v2 0/3] docs: add advanced search capability
by Daniel P. Berrangé 11 Apr '19

11 Apr '19

Andrea suggested it would be nice to redirect the search box to a local search page which then let the user submit a site-restricted search to google for website vs wiki vs mailing lists. I took a slightly different approach here, and instead simply popup an extra set of radio buttons below the main search field. This lets the user select the site to search straightaway without the intermediate page. Changed in v2: - Add missing rules for installing javascript - Use mediawiki search - Search dev & users lists separately - Whitespace fixes Daniel P.

[libvirt] [PATCH] security: apparmor: make vhost-net access a static rule
by Christian Ehrhardt 10 Apr '19

10 Apr '19

So far we were detecting at guest start if any devices needed vhost net and only if that was true added a rule for /dev/vhost-net. It turns out that it is an absolutely valid case to start a guest without any vhost-net networking but later on wanting to hotplug such a device which then would be denied by apparmor. Unfortunately there also is no security labeling callback involved other than the one to /dev/net/tun. But on the other hand vhost-net is no more new and considered rather safe. Therefore drop the old detection and just add it as a static rule.

[libvirt] [PATCH] tests: Fix MinGW build for domaincapstest
by Andrea Bolognani 10 Apr '19

10 Apr '19

Commit 5b9819eedc71 started using the virFileWrapper APIs in the test program, and correctly called them only in the section of code guarded by WITH_QEMU; however, a single call to the virFileWrapperClearPrefixes() function ended up in the hypervisor-agnostic section, causing a build failure on MinGW. Move the call to the QEMU-only section; while at it, also drop the virFileWrapperRemovePrefix() calls, which are entirely redundant since we'd drop all prefixes immediately afterwards anyway. Signed-off-by: Andrea Bolognani <abologna(a)redhat.com> --- Another approach would be to simply drop the call to virFileWrapperClearPrefixes(), but there really is no point in removing prefixes one by one when we can just clear all of them in one fell swoop. tests/domaincapstest.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/tests/domaincapstest.c b/tests/domaincapstest.c index 3ee95a4b58..a9922e1edb 100644 --- a/tests/domaincapstest.c +++ b/tests/domaincapstest.c @@ -451,9 +451,7 @@ mymain(void) "x86_64", VIR_DOMAIN_VIRT_KVM); virObjectUnref(cfg); - virFileWrapperRemovePrefix(SYSCONFDIR "/qemu/firmware"); - virFileWrapperRemovePrefix(PREFIX "/share/qemu/firmware"); - virFileWrapperRemovePrefix("/home/user/.config/qemu/firmware"); + virFileWrapperClearPrefixes(); #endif /* WITH_QEMU */ @@ -476,8 +474,6 @@ mymain(void) DO_TEST_BHYVE("fbuf", "/usr/sbin/bhyve", &bhyve_caps, VIR_DOMAIN_VIRT_BHYVE); #endif /* WITH_BHYVE */ - virFileWrapperClearPrefixes(); - return ret; } -- 2.20.1

[libvirt] [PATCH 0/4] qemu: Honor memory mode='strict'
by Michal Privoznik 10 Apr '19

10 Apr '19

If there's a domain configured as: <currentMemory unit='MiB'>4096</currentMemory> <numatune> <memory mode='strict' nodeset='1'/> </numatune> but there is not enough memory on NUMA node 1 the domain will start successfully because we allow it to allocate memory from other nodes. This is a result of some previous fix (v1.2.7-rc1~91). However, I've tested my fix successfully on a NUMA machine with F29 and recent kernel. So the kernel bug I'm mentioning in 4/4 is probably fixed then and we can drop the workaround.

[libvirt] [jenkins-ci PATCH 0/7] Update libosinfo/osinfo-db-tools dependencies
by Fabiano Fidêncio 10 Apr '19

This patch set updates both libosinfo and osinfo-db-tools deps. The changes done are, basically: libosinfo: - drop gnome-common - drop intltool osinfo-db-tools: - drop gnome-common - drop intltool - add python3 - add python3-pytest - add python3-requests Together with those changes: - gnome-common has been dropped from the mappings as the only consumers were libosinfo and osinfo-db-tools. - `make check` is not ran for CentOS 7 anymore, as the osinfo-db-tools testes depend on python3.

[libvirt] [PATCH] build-aux: ensure all scripts are included in EXTRA_DIST
by Daniel P. Berrangé 09 Apr '19

09 Apr '19

Few of the scripts in build-aux are included in EXTRA_DIST. This is not a serious problem since they are primarily tools intended for developers upstream, and downstream builds won't need them. Having them missing, however, complicates downstream patching because it means patches that are auto-exported from git will fail to apply if they include a change to a file in build-aux/. By bundling all these scripts in the dist we make patching more straightforward. Signed-off-by: Daniel P.

[libvirt] [PATCH 0/6] readline: Drop obsolete code, add pkg-config support
by Andrea Bolognani 09 Apr '19

09 Apr '19

This series drops a bunch of compatibility code that's no longer necessary to support our target platforms and introduces support for getting readline's CFLAGS and LIBS via pkg-config, which in turn makes it possible to automatically enable the feature on FreeBSD. There are a couple of caveats: * while most of the existing kludges are dropped, a new one had to be introduced :( The upsides are that the new kludge is small and straightforward, and that there's an expiration date on it already, since a patch making it unnecessary has already been provided for upstream readline; * autodetection on macOS still doesn't work because of a downstream packaging issue, but that's not any worse than the current situation anyway.

[libvirt] [PATCH v2 0/6] lxc: Add suport to virConnectGetAllDomainStats
by Julio Faracco 09 Apr '19

09 Apr '19

This series has a collection of new methods to enable support for virConnectGetAllDomainStats() to LXC driver. The only difference is Disk Stats. It needs to consider only the host file system operations as a valid block device. So, other disks should start with index 1..N. Other difference is an implementation of Kernel Memory CGroup to grab this info from each LXC container. - v1-v2: Added suggestions made by Peter Krempa.

[libvirt] [PATCH] snapshot: Fix use-after-free during snapshot delete
by Eric Blake 08 Apr '19

08 Apr '19

Commit b647d2195 introduced a use-after-free situation when the caller is trying to delete a snapshot and its children: if the callback function deletes the parent, it is no longer safe to query the parent to learn which children also need to be deleted (where we previously saved deleting the parent for last). To fix the problem, while still maintaining support for topological visits of callback functions, we have to stash off any information needed for later traversal prior to using a callback function (virDomainMomentForEachChild already does this, it is only virDomainMomentActOnDescendant that was running into problems). Sadly, the testsuite did not cover the problem at the time. Worse, even though I later added commit 280a2b41e to catch problems like this, and even though that test is indeed sufficient to detect the problem when run under valgrind or suitable MALLOC_PERTURB_ settings, I'm guilty of not running the test in such an environment. Thus, v5.2.0 has a regression that could have been prevented had we used the testsuite to its full power. On the bright side, deleting snapshots requires ACL domain:snapshot, which is arguably as powerful as domain:write, so I don't think this use-after-free forms a security hole. At some point, it would be nice to convert virDomainMomentObj into a virObject, at which point, the solution is even simpler: add virObjectRef/Unref around the callback. But as that will require auditing even more places in the code, I went with the simplest patch for the regression fix.

[libvirt] CFP: KVM Forum 2019
by Paolo Bonzini 06 Apr '19

06 Apr '19

================================================================ KVM Forum 2019: Call For Participation October 30-November 1, 2019 - Lyon Convention Center - Lyon, France (All submissions must be received before June 15, 2019 at 23:59 PST) ================================================================= KVM Forum is an annual event that presents a rare opportunity for developers and users to meet, discuss the state of Linux virtualization technology, and plan for the challenges ahead. We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2019. At this highly technical conference, developers driving innovation in the KVM virtualization stack (Linux, KVM, QEMU, libvirt) can meet users who depend on KVM as part of their offerings, or to power their data centers and clouds. KVM Forum will include sessions on the state of the KVM virtualization stack, planning for the future, and many opportunities for attendees to collaborate. As we celebrate ten years of KVM development in the Linux kernel, KVM continues to be a critical part of the FOSS cloud infrastructure. This year, KVM Forum is joining Open Source Summit in Lyon, France. Selected talks from KVM Forum will be presented on Wednesday October 30 to the full audience of the Open Source Summit. Also, attendees of KVM Forum will have access to all of the talks from Open Source Summit on Wednesday. https://events.linuxfoundation.org/events/kvm-forum-2019/program/call-for-p… Suggested topics: * Scaling, latency optimizations, performance tuning, real-time guests * Hardening and security * New features * Testing KVM and the Linux kernel: * Nested virtualization * Resource management (CPU, I/O, memory) and scheduling * VFIO: IOMMU, SR-IOV, virtual GPU, etc. * Networking: Open vSwitch, XDP, etc. * virtio and vhost * Architecture ports and new processor features QEMU: * Management interfaces: QOM and QMP * New devices, new boards, new architectures * Graphics, desktop virtualization and virtual GPU * New storage features * High availability, live migration and fault tolerance * Emulation and TCG * Firmware: ACPI, UEFI, coreboot, U-Boot, etc. Management and infrastructure * Managing KVM: Libvirt, OpenStack, oVirt, etc. * Storage: Ceph, Gluster, SPDK, etc.r * Network Function Virtualization: DPDK, OPNFV, OVN, etc. * Provisioning ======================== SUBMITTING YOUR PROPOSAL ======================== Abstracts due: June 15, 2019 Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length up to 45 minutes. Submit your proposal here: https://events.linuxfoundation.org/events/kvm-forum-2019/program/call-for-p… Please only use the categories "presentation" and "panel discussion" You will receive a notification whether or not your presentation proposal was accepted by August 12, 2019. Speakers will receive a complimentary pass for the event. In case your submission has multiple presenters, only the primary speaker for a proposal will receive a complimentary event pass. For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, focus on work that needs to be done, difficulties that haven't yet been solved, and on decisions that other developers should be aware of. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2019_BOF Let people you think who might be interested know about your BOF, and encourage them to add their names to the wiki page as well. Please add your ideas to the list before KVM Forum starts. PANEL DISCUSSIONS If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your the abstract. We will request full biographies if a panel is accepted. ============== HOTEL / TRAVEL ============== This year's event will take place at the Lyon Conference Center. For information on hotels close to the conference, please visit https://events.linuxfoundation.org/events/kvm-forum-2019/attend/venue-trave…. Information on conference hotel blocks will be available later in Spring 2019. ================= DATES TO REMEMBER ================= Submission deadline: Saturday, June 15 at 23:59 PST Notification: Monday, August 12 Schedule announced: Friday, August 16 Slides due date: Wednesday, October 23 Event dates: Wednesday, October 30 - Friday, November 1 Thank you for your interest in KVM. We're looking forward to your submissions and seeing you at the KVM Forum 2019 in October! -your KVM Forum 2019 Program Committee Please contact us with any questions or comments at kvm-forum-2019-pc(a)redhat.com

[libvirt] [PATCH] tests: fix mocking of stat() / lstat() functions
by Daniel P. Berrangé 05 Apr '19

05 Apr '19

Quite a few of the tests have a need to mock the stat() / lstat() functions and they are taking somewhat different & inconsistent approaches none of which are actually fully correct. This is shown by fact that 'make check' fails on 32-bit hosts. Investigation revealed that the code was calling into the native C library impl, not getting intercepted by our mocks. The POSIX stat() function might resolve to any number of different symbols in the C library. The may be an additional stat64() function exposed by the headers too. On 64-bit hosts the stat & stat64 functions are identical, always refering to the 64-bit ABI. On 32-bit hosts they refer to the 32-bit & 64-bit ABIs respectively. Libvirt uses _FILE_OFFSET_BITS=64 on 32-bit hosts, which causes the C library to transparently rewrite stat() calls to be stat64() calls. Libvirt will never see the 32-bit ABI from the traditional stat() call. We cannot assume this rewriting is done using a macro. It might be, but on GLibC it is done with a magic __asm__ statement to apply the rewrite at link time instead of at preprocessing. In GLibC there may be two additional functions exposed by the headers, __xstat() and __xstat64(). When these exist, stat() and stat64() are transparently rewritten to call __xstat() and __xstat64() respectively. The former symbols will not actally exist in the library at all, only the header. The leading "__" indicates the symbols are a private impl detail of the C library that applications should not care about. Unfortunately, because we are trying to mock replace the C library, we need to know about this internal impl detail. With all this in mind the list of functions we have to mock will depend on several factors - If _FILE_OFFSET_BITS is set, then we are on a 32-bit host, and we only need to mock stat64 and __xstat64. The other stat / __xstat functions exist, but we'll never call them so they can be ignored for mocking. - If _FILE_OFFSET_BITS is not set, then we are on a 64-bit host and we should mock stat, stat64, __xstat & __xstat64. Either may be called by app code. - If __xstat & __xstat64 exist, then stat & stat64 will not exist as symbols in the library, so the latter should not be mocked. The same all applies to lstat() These rules are complex enough that we don't want to duplicate them across every mock file, so this centralizes all the logic in a helper file virmockstathelper.c that should be #included when needed. The code merely need to provide a filename rewriting callback called virMockStatRedirect(). Optionally VIR_MOCK_STAT_HOOK can be defined as a macro if further processing is needed inline.

[libvirt] [PATCH 0/2] docs: add advanced search capability
by Daniel P. Berrangé 05 Apr '19

05 Apr '19

Andrea suggested it would be nice to redirect the search box to a local search page which then let the user submit a site-restricted search to google for website vs wiki vs mailing lists. I took a slightly different approach here, and instead simply popup an extra set of radio buttons below the main search field. This lets the user select the site to search straightaway without the intermediate page. Daniel P.

Andrea's ChangeLog patches reminder me that I attempted something similarish once, and also tried to drop our custom website search: http://www.redhat.com/archives/libvir-list/2016-May/msg01616.html danpb recommended I just make our search bar use google instead but I never made the attempt. 3 years later here it is. Patch #1 makes the switch but doesn't remove anything Patch #2 drops index.py, the search indexer Patch #3 drops search.php and all the references to it. libvirt.org/search.php is still a valid URL so this may break some links, even though at the moment the page prints virtually nothing except some boilerplate text.

[libvirt] [PATCH] network: drop back compat code loading actual bridge name

[libvirt] Reproducible VM start bug which affects libvirt 5.1.0 and 5.2.0
by Frank Schreuder 04 Apr '19

04 Apr '19

Hello, I am currently running into a reproducible libvirt bug which affects libvirt 5.1.0 and 5.2.0. There seem to be a racecondition in the nwfilter-define and virsh start commands. Several times a day I'm not able to start a VM anymore with the following error message: error: Failed to start domain test error: internal error: Failed to apply firewall rules /sbin/iptables -w -I FORWARD 1 -j libvirt-in: iptables v1.6.0: Couldn't load target `libvirt-in':No such file or directory To fix this issue I have to restart libvirt. Some iptable chains are missing, which is probably caused by a nwfilter-define operation. I'm able to reproduce this bug within 2 hours by running 2 loops. One loop is defining nwfilters and the second loop is destroying and starting multiple VMs. I found an entry in the changelog of libvirt 5.1.0, which seems related to this bug: Create private chains for virtual network firewall rules Historically firewall rules for virtual networks were added straight into the base chains. This works but has a number of bugs and design limitations. To address them, libvirt now puts firewall rules into its own chains. Note that with this change the filter, nat and mangle tables are required for both IPv4 and IPv6. So far I am not able to reproduce this bug on libvirt 5.0.0. Is there any information I can provide to the mailinglist to help debug and/or fix this bug? I am also willing to test patches. With kind regards, Frank Schreuder

[libvirt] [PATCH v3 00/36] network: refactor to decouple virt drivers from network driver
by Daniel P. Berrangé 04 Apr '19

04 Apr '19

An update to v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00681.html v2: https://www.redhat.com/archives/libvir-list/2019-February/msg01581.html Currently the network driver registers a set of callbacks with the virt driver in order to handle allocating/releasing network ports associated with guest NICs. This series introduces a virNetworkPortPtr object and associated XML that describes a network port.

[libvirt] [PATCH] docs: stop advertizing FTP or HTTP for downloads of libvirt

[libvirt] CfP VHPC19: HPC Virtualization-Containers: Paper due May 1, 2019 (extended)
by VHPC 19 03 Apr '19

03 Apr '19

==================================================================== CALL FOR PAPERS 14th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '19) held in conjunction with the International Supercomputing Conference - High Performance, June 16-20, 2019, Frankfurt, Germany. (Springer LNCS Proceedings) ==================================================================== Date: June 20, 2019 Workshop URL: http://vhpc.org Paper Submission Deadline: May 1, 2019 (extended) Springer LNCS, rolling abstract submission Abstract/Paper Submission Link: https://edas.info/newPaper.php?c=25685 Call for Papers Containers and virtualization technologies constitute key enabling factors for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Various virtualization-containerization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; lastly, unikernels provide for many virtualization benefits with a minimized OS/library surface. I/O Virtualization in turn allows physical network interfaces to take traffic from multiple VMs or containers; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology is furthermore enabling virtualization of HPC infrastructures. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC, containers-virtualization and the cloud.

[libvirt] Release of libvirt-5.2.0
by Daniel Veillard 03 Apr '19

03 Apr '19

It's out, a bit late but the signed tarball and rpms are at the usual place and it's tagged in git: ftp://libvirt.org/libvirt/ I also pushed the python bindings, with only a single patch since 5.1.0 at: ftp://libvirt.org/libvirt/python/ Note that it's a release with rather large changes, new features and removal of some deprecated init scripts, and as usual a large amount of improvement and bug fixes: New features: - Add Storage Pool Capabilities output Add support to list an enumerated list of supported Storage Pools via the virConnectGetCapabilities API when connected via a Storage Driver. Add support to get a more detailed list XML output Storage Pool Capabilities vis the virConnectGetStoragePoolCapabilites API. - qemu: Support virtio-{non-}transitional device models virtio-transitional and virtio-non-transitional model values were added to the QEMU driver for the following devices: disk, interface, filesystem, rng, vsock, memballoon, controller type scsi, controller type virtio-serial, input bus virtio type passthrough, hostdev type scsi_host. These new models can be used to give fine grained control over what virtio device version is presented to the guest. - qemu: Enable firmware autoselection Libvirt allows users to provide loader path for some time now. However, this puts some burden on users because they need to know what firmware meets their requirements. Now that QEMU ships firmware description files this burden can be moved onto libvirt. It is as easy as setting the firmware attribute in the os element (accepted values are bios and efi). Moreover, libvirt automatically enables domain features needed for firmware it chooses. - snapshots: Add support for topological listings A new flag VIR_DOMAIN_SNAPSHOT_LIST_TOPOLOGICAL is available for the various snapshot listing APIs such as virDomainListAllSnapshots(). For drivers that support the flag, the listed snapshots are guaranteed to be sorted such that parents occur before children. - Xen: Add support for max grant frames setting Add support for Xen's max_grant_frames setting by adding a new xenbus controller type with a maxGrantFrames attribute. E.g. <controller type='xenbus' maxGrantFrames='64'/> - qemu: Add support for parallel migration With QEMU 4.0.0 libvirt can enable parallel migration which causes the memory pages to be processed in parallel by several threads and sent to the destination host using several connections at the same time. This may increase migration speed in case a single thread is unable to saturate the network link. Removed features: - Drop support for Upstart and "Red Hat" init scripts Not a single one of the platforms we target still uses Upstart, and the Upstart project itself has been abandoned for several years now; the same is true for the "Red Hat" (really System V) init scripts, since RHEL 7 and later releases use systemd. Improvements: - Report class information for PCI node device capability. - Split setup of IPv4 and IPv6 top level chain The requirement resulting from private chains improvement done in v5.1.0 was refined so that only tables from corresponding IP version are required. This means that if a network doesn't have IPv6 enabled then those tables are not required. - Don't default to building the QEMU driver Historically, the QEMU driver has been special in that it was enabled by default, with the option to explicitly opt-out of it; starting now, we're enabling it opportunistically if we detect that all requirements are available, just like we do with other drivers. Bug fixes: - virt-host-validate: Fix IOMMU check on s390x - qemu: Allow creating pSeries guests with graphics and no USB mouse It's now possible to prevent libvirt from automatically adding a USB mouse to pSeries guests by including a USB tablet in the input XML: doing so is desiderable as using a tablet results in a much better user experience when working with GUIs. - qemu: Set $HOME and XGD variables for qemu:///system guests This avoids files being accidentally created under / or the guests not being able to start because they lack the necessary permissions to write to that location. Thanks everybody for your contributions for this release, be it with bug reports, patches, reviews, documentation, etc... Enjoy the release !

[libvirt] deadlock in remoteDispatchDomainUndefine vs daemonStreamHandleAbort
by Christian Ehrhardt 03 Apr '19

03 Apr '19

Hi, I happened to analyze a bug [1] report I got from a friend and for quite a while it was rather elusive. But I now finally got it reproducible [2] enough to share it with the community. The TL;DR of what I see is: - an automation with python-libvirt gets a SIGINT - cleanup runs destroy and further undefine - the guest closes FDs due to SIGINT and/or destroy which triggers daemonStreamHandleAbort - those two fight over the lock There I get libvirtd into a deadlock which ends up with all threads dead [4] and two of them fighting [3] (details) in particular. The to related stacks summarized are like: daemonStreamHandleWrite (failing to write) -> daemonStreamHandleAbort (closing things and cleaning up) -> ... virChrdevFDStreamCloseCb virMutexLock(&priv->devs->lock); # there is code meant to avoid such issues emitting "Unable to close" if a lock is held # but the log doesn't show this triggering with debug enabled #10 seems triggered via an "undefine" call remoteDispatchDomainUndefine ... -> virChrdevFree ... -> virFDStreamSetInternalCloseCb -> virObjectLock(virFDStreamDataPtr fdst) -> virMutexLock(&obj->lock); # closing all streams of a guest (requiring the same locks) While that already feels quite close I struggle to see where exactly we'd want to fix it. But finally having a repro-script [2] I hope that someone else here might be able to help me with that. After all it is a race - on my s390x system it triggers usually <5 tries, while on x86 I have needed up to 18 runs of the test to hang. Given different system configs it might be better or worse for you. FYI we hit this with libvirt 4.0 initially but libvirt 5.0 was just the same. I haven't built 5.1 or a recent master, but the commits since 5.0 didn't mention any issue that seems related. OTOH I'm willing and able to build and try suggestions if anyone comes up with ideas.
