[libvirt] [PATCH glib] Fix check for libvirt optional functions
by Daniel P. Berrange 28 Jul '16

28 Jul '16

The checks for virDomainOpenGraphicsFD and virNetworkGetDHCPLeases in configure are simply trying to compile and link a test program. This was assuming that libvirt was installed in /usr/lib & /usr/include, which is not always the case.

[libvirt] logging: Libvirtd could not create its own logfile, when the path /var/log/libvirt is not exist.
by weifuqiang 28 Jul '16

28 Jul '16

Hi all: Libvirtd could not create its own logfile, such as /var/log/libvirt/libvirtd.log, when the path /var/log/libvirt is not exist. It may be a problem,I think,so try to make patch when open file failed in virLogAddOutputToFile. or any better idea? ------------ Libvirtd just creates its logfile, such as /var/log/libvirt/libvirtd.log, DURING INSTALLATION. If the logfile(we mean its path here,that's /var/log/libvirt/) is deleted during its runtime, even if we restart libvirtd, such file would not be generated automatically, thus, the logs are all missing after then, it becomes impossible to debug problems after then as well. So, we try to mkdir the deleted path after restarting libvirtd. Or, any better idea? Thanks in advance. Wei Fuqiang

[libvirt] [PATCH] virconf: Fix config file path construction
by Erik Skultety 27 Jul '16

27 Jul '16

Since commit c4bdff19, the path to the configuration file has been constructed in the following manner: - if no config filename was passed to virConfLoadConfigPath, libvirt.conf was used as default - otherwise the filename was concatenated with "<config_dir>/libvirt/libvirt%s%s.conf" which in admin case resulted in "libvirt-libvirt-admin.conf.conf". Obviously, this non-existent config led to ignoring all user settings in libvirt-admin.conf. This patch requires the config filename to be always provided as an argument with the concatenation being simplified.

[libvirt] [PATCH] admin: Fix default uri config option name s/admin_uri_default/uri_default
by Erik Skultety 27 Jul '16

27 Jul '16

The original name 'admin_uri_default' was introduced to our code by commit dbecb87f. However, at that time we already had a separate config file for admin library but the commit mentioned above didn't properly adjust the config's option name. The result is that when we're loading the config, we check a non-existent config option (there's not much to do with the URIs anyway, since we only allow local connection). Additionally, virt-admin's man page documents, that the default URI can be altered by setting admin_uri_default option. So the fix proposed by this patch leaves the libvirt-admin.conf as is and adjusts the naming in the code as well as in the virt-admin's man page.

[libvirt] [PATCH] virsh: use virConnectGetDomainCapabilities with maxvcpus
by Shivaprasad G Bhat 27 Jul '16

27 Jul '16

The following patch fixes the maxvcpus output on PPC64. Earlier I tried fixing this in kvmGetMaxVcpus() which was later decided to be document not use the virConnectGetMaxVcpus() instead use the virConnectGetDomainCapabilities api. I have not implemented the suggestedcpus as mentioned in my previous patches in this yet. Previous series fixing the virConnectGetDomainCapabilities can be found here. https://www.redhat.com/archives/libvir-list/2016-June/msg01873.html --- Shivaprasad G Bhat (1): virsh: use virConnectGetDomainCapabilities with maxvcpus tools/virsh-host.c | 33 +++++++++++++++++++++++++++++---- 1 file changed, 29 insertions(+), 4 deletions(-) -- Signature

[libvirt] [PATCH sandbox] image: Rename 'create' and 'delete' to 'prepare' and 'purge'
by Daniel P. Berrange 27 Jul '16

27 Jul '16

Currently we have three virt-sandbox-image commands - 'create' - downloads a template and creates qcow2 - 'delete' - deletes template qcow2 files - 'run' - runs an instance of a template The 'run' command is generating a transient guest which disappears when it stops. We want to have the ability to create / delete persistent guests later, for which the command names "create" and "delete" are a natural fit. So to avoid clash, rename the existing "create" command to "prepare" and the "delete" command to "purge" --- libvirt-sandbox/image/cli.py | 28 ++++++++++++++-------------- 1 file changed, 14 insertions(+), 14 deletions(-) diff --git a/libvirt-sandbox/image/cli.py b/libvirt-sandbox/image/cli.py index 66854e4..3a5ccfa 100644 --- a/libvirt-sandbox/image/cli.py +++ b/libvirt-sandbox/image/cli.py @@ -68,13 +68,13 @@ def get_template_dir(args): tmpl = template.Template.from_uri(args.template) return "%s/%s" % (args.template_dir, tmpl.source) -def delete(args): +def purge(args): tmpl = template.Template.from_uri(args.template) source = tmpl.get_source_impl() source.delete_template(template=tmpl, templatedir=get_template_dir(args)) -def create(args): +def prepare(args): tmpl = template.Template.from_uri(args.template) source = tmpl.get_source_impl() source.create_template(template=tmpl, @@ -91,7 +91,7 @@ def run(args): # Create the template image if needed if not source.has_template(tmpl, template_dir): - create(args) + prepare(args) name = args.name if name is None: @@ -197,26 +197,26 @@ Example supported URI formats: """) return parser -def gen_delete_args(subparser): - parser = gen_command_parser(subparser, "delete", - _("Delete template data")) +def gen_purge_args(subparser): + parser = gen_command_parser(subparser, "purge", + _("Purge cached template")) requires_debug(parser) requires_template(parser) requires_template_dir(parser) - parser.set_defaults(func=delete) + parser.set_defaults(func=purge) -def gen_create_args(subparser): - parser = gen_command_parser(subparser, "create", - _("Create image from template data")) +def gen_prepare_args(subparser): + parser = gen_command_parser(subparser, "prepare", + _("Prepare local template")) requires_debug(parser) requires_template(parser) requires_connect(parser) requires_template_dir(parser) - parser.set_defaults(func=create) + parser.set_defaults(func=prepare) def gen_run_args(subparser): parser = gen_command_parser(subparser, "run", - _("Run an already built image")) + _("Run an instance of a template")) requires_debug(parser) requires_name(parser) requires_template(parser) @@ -248,8 +248,8 @@ def main(): parser = argparse.ArgumentParser(description="Sandbox Container Image Tool") subparser = parser.add_subparsers(help=_("commands")) - gen_delete_args(subparser) - gen_create_args(subparser) + gen_purge_args(subparser) + gen_prepare_args(subparser) gen_run_args(subparser) gen_list_args(subparser) -- 2.7.4

[libvirt] [PATCH v2 00/10] Remove caching of address sets
by Tomasz Flendrich 27 Jul '16

27 Jul '16

From: Tomasz Flendrich <Darge(a)users.noreply.github.com> These patches delete the caching of pci, virtioSerial and ccw address sets. I am deleting them, because they can be recalculated from the domain definition, and there's no point in keeping redundant data, especially because handling a persistent cache of addresses required using functions that released addresses. These functions aren't useful anymore, so they are dropped too. I know that USB addresses were added and that they are cached now. I am sure that they can be calculated on demand too though. If this gets accepted, I will rebase the other patches that depend on this one, making functions less dependant on qemu, and removing the code duplication. Changes in v2: * I rebased it, because there were some changes that added a usb address set. * virDomainReleaseDeviceAddress is no longer deleted, because it's used for usb addresses. It also means that in qemu_hotplug.c, this function's calls are not deleted anymore. * In qemu_hotplug.c, in one place, virDomainPCIAddressSetFree() was previously called after the "error:" label. I moved it to the "cleanup:", so the address set is freed even if an error occurs. * Add one missing free of pci address set, in qemuDomainAttachNetDevice().

[libvirt] [PATCH v2 00/10] Test persistent device attachment
by Tomasz Flendrich 27 Jul '16

27 Jul '16

Changes in v2: * rebased This patch requires another one, otherwise a small conflict appears: https://www.redhat.com/archives/libvir-list/2016-July/msg00402.html In qemu_driver.c, two functions were split to have less responsibility. They were also modified so that they could be used in qemuhotplugtest. Now instead of running different functions to attach different device types, a generic function is run. Hopefully this will result in more device types tested in the future. Suggestions on how to name these two new functions are very welcome. In the future, if one uses the following command: virsh attach-device --live --config the new device will have the same address assigned in both live and config domain. To make sure that everything will work properly after making these changes, I reworked qemuhotplug.c to work with attaching devices to persistent domains. So far, there is only one test for persistent attachment. I will add more testcases as soon as I hear some feedback on these changes. qemuhotplugtest.c should first be modified anyway, so that the three xmls's filenames (basis domain xml, device xml, expected xml) are stated explicitly instead of being calculated. This will allow for more flexibility in testing and less xml files duplicates. Tomasz Tomasz Flendrich (10): Change parameters to qemuDomainAttachDeviceLive Remove an unnecessary variable Split qemuDomainAttachDeviceFlags in two Narrow down a parameter Split qemuDomainDetachDeviceFlags in two Make qemu attach/detach functions public Narrow down a parameter to function Use more generic functions in qemuhotplugtest Make qemuhotplugtest work with persistent domains Add a persistent attachment testcase src/qemu/qemu_driver.c | 221 +++++++++++---------- src/qemu/qemu_driver.h | 14 ++ tests/qemuhotplugtest.c | 213 ++++++++++++-------- .../qemuhotplug-base-config+qemu-agent+config.xml | 45 +++++ .../qemuhotplug-base-config.xml | 40 ++++ 5 files changed, 349 insertions(+), 184 deletions(-) create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-config+qemu-agent+config.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-config.xml -- 2.7.4

[libvirt] [PATCH v5] libxl: implement virDomainBlockStats
by Joao Martins 27 Jul '16

27 Jul '16

Introduce initial support for domainBlockStats API call that allow us to query block device statistics. openstack nova uses this API call to query block statistics, alongside virDomainMemoryStats and virDomainInterfaceStats. Note that this patch only introduces it for VBD for starters. QDisk would come in a separate patch series. A new statistics data structure is introduced to fit common statistics among others specific to the underlying block backends. For the VBD statistics on linux these are exported via sysfs on the path: "/sys/bus/xen-backend/devices/vbd-<domid>-<devid>/statistics" To calculate the block devno libxlDiskPathToID is introduced. Each backend implements its own function to extract statistics and let there be handled the different platforms. VBD stats are exposed in reqs and number of sectors from blkback, and it's up to us to convert it to sector sizes. The sector size is gathered through xenstore in the device backend entry "physical-sector-size". BlockStatsFlags variant is also implemented which has the added benefit of getting the number of flush requests. Signed-off-by: Joao Martins <joao.m.martins(a)oracle.com> --- Changes since v4: - No need to handle virtpath as devid - return id = -1 instead - Rework compilation of BlockStatsVBD compilation on other platforms. - Use disk->dst as opposed to plain path to also cover the case when input virtpath is path to file.

[libvirt] [PATCH] qemu: Use legacy USB on ppc64
by Andrea Bolognani 26 Jul '16

26 Jul '16

Commit 8156493d8db9 changed libvirt so that '-device pci-ohci' would be used instead of '-usb' on ppc64 when no specific USB controller model had been specified in the guest configuration. While the device that ends up being presented by the guest is exactly the same, '-usb' causes it to be assigned to PCI address 00:00.0 while '-device pci-ohci', being subject to the regular PCI address assignment logic, will be at a different address. This PCI address mismatch breaks migration of existing guests to new libvirt versions. Luckily, when QEMU has switched its default '-usb' controller from pci-ohci to nec-usb-xhci (QEMU commit 57040d451315), it has done so without affecting older machine types, which means we can keep using '-usb' without risking guest ABI breakage.

[libvirt] [RFC] Switch to nftables from netfilter
by Michal Privoznik 26 Jul '16

26 Jul '16

Dear list, I've came across nftables [1]. They look very promising, more than old netfilter. It offers new features [2], from which I'd pick: - better performance under high traffic workloads - atomic filter/chain replacements - transactions I haven't investigated how much work will be required on our side if we try to implement the switch (well, for starters, we can have two subsystems living next to each other). I want to check what do you guys think before actually digging into the code. The nftables was merged into 3.13 Linux kernel and thus should be available on all major distros. Well, since we will have both subsystems available, we should be good to go. BTW: it's a bit shame that this nifty project hasn't received much more advertising. Looks cool so far.

[libvirt] [PATCH] qemu: Fix backwards compatibility of S390 guests
by Boris Fiuczynski 26 Jul '16

26 Jul '16

This patch reverts commit 73e4e10e62e4b1aea64b317be96af5e5488007d7 and thereby disabling the panic device autogeneration for S390 guests. In addition tests are patched as well. The reverted commit breaks backwards compatibility of S390 guests. As an example: A domain xml without a panic device can successfully be used to define on two hosts with different libvirt versions. Using this domain xml to define a domain on a host with libivrt v1.3.5 makes it impossible to migrate the domain to a host with libvirt v1.3.4 or older since libvirt v1.3.5 automatically added a panic device with model s390 which libvirt v1.3.4 or older rejects as unknown model.

[libvirt] Schedule for next release
by Daniel Veillard 26 Jul '16

26 Jul '16

About time to roll that one. I think we need to enter freese on Wednesday, then I can make rc2 on Friday, and hopefully we can push 2.1.0 on Monday or Tuesday next week. Raise a flag if that doesn't work :-) thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH v4] libxl: implement virDomainBlockStats
by Joao Martins 26 Jul '16

26 Jul '16

Introduce initial support for domainBlockStats API call that allow us to query block device statistics. openstack nova uses this API call to query block statistics, alongside virDomainMemoryStats and virDomainInterfaceStats. Note that this patch only introduces it for VBD for starters. QDisk would come in a separate patch series. A new statistics data structure is introduced to fit common statistics among others specific to the underlying block backends. For the VBD statistics on linux these are exported via sysfs on the path: "/sys/bus/xen-backend/devices/vbd-<domid>-<devid>/statistics" To calculate the block devno libxlDiskPathToID is introduced. Each backend implements its own function to extract statistics and let there be handled the different platforms. VBD stats are exposed in reqs and number of sectors from blkback, and it's up to us to convert it to sector sizes. The sector size is gathered through xenstore in the device backend entry "physical-sector-size". BlockStatsFlags variant is also implemented which has the added benefit of getting the number of flush requests. Signed-off-by: Joao Martins <joao.m.martins(a)oracle.com> --- Changes since v3: - No need for error in libxlDiskSectorSize() - Fix an identation issue. - Rework cleanup paths on libxlDiskSectorSize() - Do not unlock vm if libxlDomainObjEndJob() returns false and adjust to the newly introduced virDomainObjEndAPI() - Bump version to 2.1.0 Changes since v1: - Fix identation issues - Set ret to LIBXL_VBD_SECTOR_SIZE - Reuse VIR_STRDUP error instead of doing virReportError when we fail to set stats->backend - Change virAsprintf(...) error checking - Change error to VIR_ERR_OPERATION_FAILED when xenstore path does not exist and when failing to read stat. - Resolve issues with 'make syntax-check' with cppi installed. - Remove libxlDiskPathMatches in favor of using virutil virDiskNameParse to fetch disk and partition index. - Rename libxlDiskPathParse to libxlDiskPathToID and rework function to just convert disk and partition index to devno. - Bump version to 1.2.22 --- src/libxl/libxl_driver.c | 364 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 364 insertions(+) diff --git a/src/libxl/libxl_driver.c b/src/libxl/libxl_driver.c index f153f69..189bfb5 100644 --- a/src/libxl/libxl_driver.c +++ b/src/libxl/libxl_driver.c @@ -30,6 +30,7 @@ #include <math.h> #include <libxl.h> #include <libxl_utils.h> +#include <xenstore.h> #include <fcntl.h> #include <regex.h> @@ -72,6 +73,7 @@ VIR_LOG_INIT("libxl.libxl_driver");

[libvirt] [PATCH] qemu_monitor: search memballoon QOM device path using alias
by Pavel Hrdina 25 Jul '16

25 Jul '16

Commit 4a585a88 introduced searching QOM device path by alias, let's use it for memballoon too. This may speedup the search because in most cases we will find the correct QOM device path directly by using alias without the need for the recursion code.

[libvirt] Question about : Qemu: don't refuse to undefine a guest with NVRAM file
by Kevin Zhao 25 Jul '16

25 Jul '16

Hi Daniel, Thanks for your help about my bug fix. Now I find that I can't delete instance with nvram. The problem is really serious for AArch64, since it always needs uefi. I'm now working on this bug: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1567807, it's about Nova can't delete instance which has been booted by UEFI. I find that you have upload a patch in 2015: https://www.redhat.com/archives/libvir-list/2015-February/msg00915.html , to fix libvirt don't refuse to delete instance with NVRAM. I have a question that the patch status is ? I see that your patch has not been merged. Do we need to modify the Nova code to add support to delete nvram instance? Or just wait for Libvirt to fix? Maybe I can help when we need to modify Nova. Thanks Daniel ~ Looking forward to your response~

[libvirt] [PATCH] qemu_monitor_json: add support to search QOM device path by device alias
by Pavel Hrdina 25 Jul '16

25 Jul '16

Commit ce745914 introduced detection of actual video ram sizes to fix migration if QEMU decide to modify the values provided by libvirt. This works perfectly for domains with number of video devices up to two. If there are more than two video devices in the guest all the secondary devices in the XML will have the same memory values. This is because our current code search for QOM device path only by the device type name and all the secondary video devices has the same name "qxl". This patch introduces a new search function that will try to search a QOM device path using also device's alias if the alias is available. After that it will fallback to the old recursive code if the alias search found no results.

[libvirt] [PATCH v3] qemuhotplugtest: Add tests for ccw devices
by Tomasz Flendrich 25 Jul '16

25 Jul '16

There's a plan to rework the address handling, so testcases that verify hotplugging ccw devices will help in avoiding regression. In this commit, some files are duplicated because of the way qemuhotplug.c calculates the expected xml filenames. I plan on changing that to explicitly stating the basis domain xml, the device xml, and the expected xml. --- Changes in v3: * incorrect vde2 is removed in another .xml file, so that there are duplicates of aliases tests/qemuhotplugtest.c | 37 +++++++++++ .../qemuhotplug-ccw-virtio-1-explicit.xml | 8 +++ .../qemuhotplug-ccw-virtio-1-reverse.xml | 7 +++ .../qemuhotplug-ccw-virtio-2-explicit.xml | 8 +++ .../qemuhotplug-ccw-virtio-2.xml | 8 +++ .../qemuhotplug-ccw-virtio.xml | 8 +++ .../qemuhotplug-base-ccw-live+ccw-virtio.xml | 63 +++++++++++++++++++ ...ive-with-2-ccw-virtio+ccw-virtio-1-explicit.xml | 73 ++++++++++++++++++++++ ...live-with-2-ccw-virtio+ccw-virtio-1-reverse.xml | 73 ++++++++++++++++++++++ ...qemuhotplug-base-ccw-live-with-2-ccw-virtio.xml | 63 +++++++++++++++++++ ...-live-with-ccw-virtio+ccw-virtio-2-explicit.xml | 73 ++++++++++++++++++++++ ...-base-ccw-live-with-ccw-virtio+ccw-virtio-2.xml | 73 ++++++++++++++++++++++ .../qemuhotplug-base-ccw-live-with-ccw-virtio.xml | 63 +++++++++++++++++++ .../qemuhotplug-base-ccw-live.xml | 53 ++++++++++++++++ 14 files changed, 610 insertions(+) create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-1-explicit.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-1-reverse.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-2-explicit.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-2.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live+ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio+ccw-virtio-1-explicit.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio+ccw-virtio-1-reverse.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio+ccw-virtio-2-explicit.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio+ccw-virtio-2.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live.xml diff --git a/tests/qemuhotplugtest.c b/tests/qemuhotplugtest.c index f2e7567..0a5f068 100644 --- a/tests/qemuhotplugtest.c +++ b/tests/qemuhotplugtest.c @@ -73,6 +73,7 @@ qemuHotplugCreateObjects(virDomainXMLOptionPtr xmlopt, virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_VIRTIO_SCSI); virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_DEVICE_USB_STORAGE); + virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_VIRTIO_CCW); if (event) virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_DEVICE_DEL_EVENT); @@ -523,6 +524,42 @@ mymain(void) "device_del", QMP_OK, "chardev-remove", QMP_OK); + DO_TEST_ATTACH("base-ccw-live", "ccw-virtio", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + DO_TEST_DETACH("base-ccw-live", "ccw-virtio", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + DO_TEST_ATTACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + + DO_TEST_DETACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + DO_TEST_ATTACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2-explicit", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + + DO_TEST_DETACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2-explicit", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + /* Attach a second device, then detach the first one.

[libvirt] [PATCH v2] qemuhotplugtest: Add tests for ccw devices
by Tomasz Flendrich 22 Jul '16

22 Jul '16

These are a few simple and one complex testcases. The simple ones test attaching and detaching ccw devices with both implicitly and explicitly stated addresses. In the complex one, attaching and detaching a device should make the address free to reuse. I have plan to rework the address handling, so testcases that verify hotplugging ccw devices will help in avoiding regression. In this commit, some device files are duplicated because of the way qemuhotplug.c calculates the expected xml filenames. I plan on changing that to explicitly stating the basis domain xml, the device xml, and the expected xml. --- Changed in v2: * Add a newline to the end of qemuhotplug-ccw-virtio-2-explicit.xml, so that syntax-check doesn't complain. * Rename two files: remove the "explicit" word where the address is actually implicit.

[libvirt] gconfig: Add hostdev support v5
by Zeeshan Ali (Khattak) 22 Jul '16

22 Jul '16

It's back! :) Really intend to actually get it finished and merged this time around. Basically I mostly fixed all the minor issues in patch 3/5 (Add GVirConfigDomainHostdevPci) pointed out in last review, including treatment of on/off attributes (which is why the patch "libvirt-gconfig: Accept on/off as boolean attributes" has been dropped in this version).

[libvirt] [PATCH] nodedev: Add retry logic to read fibre channel files
by John Ferlan 22 Jul '16

22 Jul '16

https://bugzilla.redhat.com/show_bug.cgi?id=1319544 During processing of a vport_create event, udevEventHandleCallback will call udevProcessSCSIHost to read the fibre channel configuration files for wwpn, wwpn, and fabric_wwn; however, as it turns out those files may not have valid data. Rather than carry around invalid data, add some logic to re-read the files up to 5 times. If after 5 attempts things still fail, don't hold up processing any longer. The "ffffffffffffffff" value is what seems to be used to initialize the wwnn and wwpn files, while "0" or "ffffffffffffffff" have been used to initialize the fabric_wwn file (see bz 1240912 for some details). Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- This has been hanging in a local branch for a while. Figured I'd at the very least get some feedback and thoughts from others as to whether it's worth making the adjustments. Lots of details in the bz, the essentially the tester is bypassing the libvirt create vport mechanism, then wants to use the libvirt delete vHBA; however, the timing of things seems to have gotten clogged up and not all the fields in the vHBA are read properly thus the deletion cannot be done. A workaround to the issue is to run nodedev-dumpxml on the vHBA again and the data is read properly. This patch went with a retry mechanism to try and ensure the data we've read is correct.

[libvirt] [PATCH] lxc: Don't crash by forgetting to ref transient domains
by Martin Kletzander 22 Jul '16

22 Jul '16

So commit 306b3a8504 tried mimicking behaviour of commit 540c339a25, but added a virObjectRef(vm) only after virDomainObjListAdd() in lxcDomainDefineXMLFlags() and not in lxcDomainCreateXMLWithFiles(). That way undefining a domain that was started with different XML than defined will leave the domain object in a state with not enough references to then remove it. Hence any lxcDomainDestroyFlags() called afterwards crashes the daemon.

[libvirt] [PATCH RFC 0/5] lxc: Add save/restore support to lxc driver
by Katerina Koukiou 22 Jul '16

22 Jul '16

This patch series adds support for saving an running lxc domain's state into files with lxcDomainSave and restore afterwards from files with lxcDomainRestore. Usage: virsh save [domain-name] [domain-id or domain-uuid] [directory name] I use CRIU tool (https://criu.org/Main_Page) that offers checkpoint/restore functionality for containers in userspace. For the time, I have tried successfully the C/R procedure for simple sh containers and OS containers. I'll mention some notes/issues here: *I have working C/R only for non systemd hosts (on systemd host I was facing problems with CRIU). *I have not done anything for container networking. Thats should be done with --veth-pair IN=OUT option in CRIU. *In new distros, where efivars mountpoint exists, CRIU dump fails. *The only tty restored is /dev/tty1. I'll fix this in another patch, to allow more ttys. *Currently for things to work, I have slightly modified criu source. That is in criu master I have the following diff: diff --git a/criu/tty.c b/criu/tty.c index 302dd54..2226484 100644 --- a/criu/tty.c +++ b/criu/tty.c @@ -1394,8 +1394,10 @@ static int verify_info(struct tty_info *info) */ if (term_opts_missing_any(info)) { if (tty_is_master(info)) { + /* pr_err("Corrupted master peer %x\n", info->tfe->id); return -1; + */ } else if (!term_opts_missing_all(info)) { pr_err("Corrupted slave peer %x\n", info->tfe->id); return -1; Lastly, I have ready a patch that adds support for migration but I wait for feedback on this series, and I'll send the migration one later.

[libvirt] [PATCH v2] qemuhotplugtest: Add tests for ccw devices
by Tomasz Flendrich 21 Jul '16

21 Jul '16

There's a plan to rework the address handling, so testcases that verify hotplugging ccw devices will help in avoiding regression. In this commit, some device files are duplicated because of the way qemuhotplug.c calculates the expected xml filenames. I plan on changing that to explicitly stating the basis domain xml, the device xml, and the expected xml. --- Changes in v2: * the target dev in the first attachment is changed from vde2 to hda, so the device is now something hopefully valid and there are no duplicated aliases * the target dev in the second attachment is changed from vde to hdb, so now it's different than the device that was previously under this address. I did it to make sure that it's a completely new device. tests/qemuhotplugtest.c | 37 +++++++++++ .../qemuhotplug-ccw-virtio-1-explicit.xml | 8 +++ .../qemuhotplug-ccw-virtio-1-reverse.xml | 7 +++ .../qemuhotplug-ccw-virtio-2-explicit.xml | 8 +++ .../qemuhotplug-ccw-virtio-2.xml | 8 +++ .../qemuhotplug-ccw-virtio.xml | 8 +++ .../qemuhotplug-base-ccw-live+ccw-virtio.xml | 63 +++++++++++++++++++ ...ive-with-2-ccw-virtio+ccw-virtio-1-explicit.xml | 73 ++++++++++++++++++++++ ...live-with-2-ccw-virtio+ccw-virtio-1-reverse.xml | 73 ++++++++++++++++++++++ ...qemuhotplug-base-ccw-live-with-2-ccw-virtio.xml | 63 +++++++++++++++++++ ...-live-with-ccw-virtio+ccw-virtio-2-explicit.xml | 73 ++++++++++++++++++++++ ...-base-ccw-live-with-ccw-virtio+ccw-virtio-2.xml | 73 ++++++++++++++++++++++ .../qemuhotplug-base-ccw-live-with-ccw-virtio.xml | 63 +++++++++++++++++++ .../qemuhotplug-base-ccw-live.xml | 53 ++++++++++++++++ 14 files changed, 610 insertions(+) create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-1-explicit.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-1-reverse.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-2-explicit.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio-2.xml create mode 100644 tests/qemuhotplugtestdevices/qemuhotplug-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live+ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio+ccw-virtio-1-explicit.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio+ccw-virtio-1-reverse.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-2-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio+ccw-virtio-2-explicit.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio+ccw-virtio-2.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live-with-ccw-virtio.xml create mode 100644 tests/qemuhotplugtestdomains/qemuhotplug-base-ccw-live.xml diff --git a/tests/qemuhotplugtest.c b/tests/qemuhotplugtest.c index f2e7567..0a5f068 100644 --- a/tests/qemuhotplugtest.c +++ b/tests/qemuhotplugtest.c @@ -73,6 +73,7 @@ qemuHotplugCreateObjects(virDomainXMLOptionPtr xmlopt, virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_VIRTIO_SCSI); virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_DEVICE_USB_STORAGE); + virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_VIRTIO_CCW); if (event) virQEMUCapsSet(priv->qemuCaps, QEMU_CAPS_DEVICE_DEL_EVENT); @@ -523,6 +524,42 @@ mymain(void) "device_del", QMP_OK, "chardev-remove", QMP_OK); + DO_TEST_ATTACH("base-ccw-live", "ccw-virtio", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + DO_TEST_DETACH("base-ccw-live", "ccw-virtio", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + DO_TEST_ATTACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + + DO_TEST_DETACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + DO_TEST_ATTACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2-explicit", false, true, + "human-monitor-command", HMP("OK\\r\\n"), + "device_add", QMP_OK); + + DO_TEST_DETACH("base-ccw-live-with-ccw-virtio", "ccw-virtio-2-explicit", false, false, + "device_del", QMP_OK, + "human-monitor-command", HMP("")); + + /* Attach a second device, then detach the first one.

[libvirt] [RFC PATCH 0/2] nodeinfo: PPC64: Fix topology and siblings info on capabilities and nodeinfo
by Shivaprasad G Bhat 21 Jul '16

21 Jul '16

The nodeinfo output was fixed earlier to reflect the actual cpus available in KVM mode on PPC64. The earlier fixes covered the aspect of not making a host look overcommitted when its not. The current fixes are aimed at helping the users make better decisions on the kind of guest cpu topology that can be supported on the given sucore_per_core setting of KVM host and also hint the way to pin the guest vcpus efficiently. I am planning to add some test cases once the approach is accepted. With respect to Patch 2: The second patch adds a new element to the cpus tag and I need your inputs on if that is okay. Also if there is a better way. I am not sure if the existing clients have RNG checks that might fail with the approach. Or if the checks are not enoforced on the elements but only on the tags. With my approach if the rng checks pass, the new element "capacity" even if ignored by many clients would have no impact except for PPC64. To the extent I looked at code, the siblings changes dont affect existing libvirt functionality. Please do let me know otherwise. --- Shivaprasad G Bhat (2): nodeinfo: Reflect guest usable host topology on PPC64 Introduce capacity to virCapsHostNUMACellCPU to help vcpu pinning decisions src/conf/capabilities.c | 3 + src/conf/capabilities.h | 1 src/nodeinfo.c | 51 ++++++++++++++++++++++-- tests/vircaps2xmldata/vircaps-basic-4-4-2G.xml | 32 ++++++++------- tests/vircaps2xmltest.c | 1 5 files changed, 67 insertions(+), 21 deletions(-) -- Signature

[libvirt] [PATCH] Remove code duplication in domain_addr.c
by Tomasz Flendrich 21 Jul '16

21 Jul '16

Two functions, virDomainValidateDevicePCISlotsQ35 and virDomainValidateDevicePCISlotsPIIX3, had almost exactly the same code for verifying the PCI address of the primary video device. The only difference between them was the slot number. To avoid code duplication, I moved it to a new function: virDomainValidateVideoDevice. --- src/conf/domain_addr.c | 218 +++++++++++++++++++++---------------------------- 1 file changed, 94 insertions(+), 124 deletions(-) diff --git a/src/conf/domain_addr.c b/src/conf/domain_addr.c index 7abe44c..9a6f977 100644 --- a/src/conf/domain_addr.c +++ b/src/conf/domain_addr.c @@ -1391,6 +1391,82 @@ virDomainMachineIsI440FX(const virDomainDef *def) static int +virDomainValidateVideoDevice(virDomainDefPtr def, + virDomainPCIAddressSetPtr addrs, + virDomainPCIConnectFlags flags, + bool videoPrimaryEnabled, + unsigned int slot) +{ + int ret = -1;

[libvirt] RFC: disk tray opened event and changing media API cooperation
by Nikolay Shirokovskiy 21 Jul '16

21 Jul '16

Hi, all. I want to remove media if disk is ejected from guest. I can leverage tray opened event for it but this event generated if i change media thru API call too. Thus I can't just remove media on any such event. However it would be possible if libvirt do not propagate tray opened event that originates from qemuDomainUpdateDeviceFlags actions. On this way we need also to close tray back if it was originally closed so state visible to client is in sync with actual. I can imagine other cases when closing tray at the end of qemuDomainUpdateDeviceFlags will be useful. Say implementing a kind of changer in mgmt layer so that if guest ejects disk mgmt insert next media from some playlist. In this case tray should be closed so that guest will see that media is changed. In short I suggest: 1. close tray at the end of chaning/ejecting media 2. if tray is opened during the operation than mask this event from client Nikolay

[libvirt] Minor compile failure on OSX for libvirt 2.0.0
by Justin Clift 20 Jul '16

20 Jul '16

Hi all, There's a minor compile failure on OSX with libvirt 2.0.0: CC util/libvirt_util_la-virtime.lo CC util/libvirt_util_la-virtpm.lo util/virsystemd.c:524:26: error: use of undeclared identifier 'MSG_NOSIGNAL' if (sendmsg(fd, &mh, MSG_NOSIGNAL) < 0) ^ 1 error generated. make[3]: *** [util/libvirt_util_la-virsystemd.lo] Error 1 make[3]: *** Waiting for unfinished jobs....

[libvirt] [PATCHv2 0/3] Speed up hvsupport.pl
by Ján Tomko 20 Jul '16

This reduces the script execution time from 14.7s to 60 ms. Since this was by far the longest taking target from the docs/ directory and make does not parallelize across Makefiles, the savings are similar for a complete build from a fresh git checkout. The second patch shaves off 8.2s, the third 6.4s and the last one shaves off half of the remaining time. v2: * renamed parseAPIXML to getAPIFilenames * documented getAPIFilenames * comment in apibuild.py above the line that generates the data consumed by hvsupport.pl * more verbose commit messages Ján Tomko (3): hvsupport: use a regex instead of XML::XPath hvsupport: construct the group regex upfront hvsupport: skip non-matching lines early bootstrap.conf | 1 - docs/apibuild.py | 1 + docs/hvsupport.pl | 69 +++++++++++++++++++++++++++++++++++++------------------ 3 files changed, 48 insertions(+), 23 deletions(-) -- 2.7.3

[libvirt] [PATCH v4 0/7] Add support for LUKS encrypted devices
by John Ferlan 19 Jul '16

19 Jul '16

According to Dan's post commit response: http://www.redhat.com/archives/libvir-list/2016-July/msg00088.html to the v3 series: http://www.redhat.com/archives/libvir-list/2016-June/msg01935.html using a 'passphrase' usage is not desired, rather a 'volume' usage model should be used for LUKS. So patches 1 & 2 make those alterations to already pushed docs and tests Patch 3 then repurposes the 'passphrase' usage to a 'tls' usage type. I posted with this series since it removed the 'passphrase' usage and thus flushed out any errors in subsequent patches. I could hold off and repost it with the TLS changes that will also need to be made... Patches 4-7 were reviewed previously and had been given what I took as provisional ACK's; however, I reposted the changes after the most recent review "just in case". Fortunately (I guess) I didn't push them along with the other changes. In any case, there are once again posted here - the primary difference between what's posted in this series vs. what was posted previously is the change to use a "volume" secret plus a tweak to the qemuxml2argvtest to fix some issues found while making the change.

[libvirt] [PATCH] Debug: Record the VM PID in per-VM logs.
by Prerna Saxena 19 Jul '16

19 Jul '16

For certain situations such as Out-of-memory scenarios, it is helpful to record the QEMU PID in the per-VM logs, so that correlation with kernel-reported events is easier. While this is already recorded in libvirt daemon logs as a DEBUG message, I believe it merits more attention :-) Hence introducing it in per-VM log.

[libvirt] [PATCH] virt-admin: Output srv-threadpool-info data as unsigned int rather than signed
by Erik Skultety 19 Jul '16

19 Jul '16

Internally, all the data are represented as unsigned int, it is also documented in the header file that users should use our exported constants that also indicate that the data should be unsigned int. However, when polling for the current server threadpool's configuration, virt-admin uses an incorrect formatting parameter '%d' for printf. Instead, virt-admin should use formatting parameter '%u'.

[libvirt] [PATCH 0/7] Error path cleanup for hotplug and one function move/rename
by John Ferlan 19 Jul '16

19 Jul '16

During review of the LUKS series: http://www.redhat.com/archives/libvir-list/2016-July/msg00488.html it was noted that the error paths should use bools rather than goto failxxx type labels. So this series does that for a few of the affect APIs. There's also changes to qemuDomainAttachMemory since it seems it wasn't properly handling 'props' at least w/r/t how qemuDomainAttachRNGDevice would clean things up. Finally - another part of the review noted that the qemu command line comma escaping could be made more available since the storage driver would potentially need it to build the qemuimg command line. So I moved to virqemu and renamed.

[libvirt] [PATCH 0/9] Various patches as a result of Coverity
by John Ferlan 19 Jul '16

19 Jul '16

Been piling up a few Coverity changes, the later patches aren't anything critical, but the first few are newer and it seems more likely to be hit in common paths. In particular, the first 2 are from recent virconf changes.

[libvirt] Adding ips and routes to type="ethernet" devices
by Ruben Kerkhof 19 Jul '16

19 Jul '16

Hi all, I've been playing with the recently added support for adding ips and routes to a type"ethernet" kind of device. My goal is to get rid of bridging and use host routes (/32) combined with Bird for a pure layer3 setup. Something similar to what https://www.projectcalico.org/ is doing Instead of p2p addresses with peers they use device routes (ip route add 192.168.0.1/32 dev vnet0) combined with static arp entries. I am a bit stuck though. I've created the vm with a tap device: <interface type='ethernet'> <mac address='00:1a:4a:1b:d9:cc'/> <model type='virtio'/> <rom bar="off"/> <source> <ip address='192.168.42.41' family='ipv4' peer='192.168.42.42' prefix='32'/> <route family='ipv4' address='192.168.100.0' prefix='24' gateway='192.168.42.42'/> </source> </interface> After starting, the link stays down and no ips or routes are being created: root@test1: ~# ip link show dev vnet0 15: vnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether fe:1a:4a:1b:d9:cc brd ff:ff:ff:ff:ff:ff root@test1: ~# ip route show default via 10.10.5.1 dev br1010 10.10.5.0/24 dev br1010 proto kernel scope link src 10.10.5.2 I feel like I'm missing a step. Who is responsible for setting the link up, it this libvirtd, qemu, or do I need to write a qemu-ifup script? Any help is greatly appreciated. Kind regards, Ruben Kerkhof

[libvirt] [PATCH 00/10] Remove caching of address sets

These patches delete the caching of pci, virtioSerial and ccw address sets. I am deleting them, because they can be recalculated from the domain definition, and there's no point in keeping redundant data, especially because handling a persistent cache of addresses required using functions that released addresses. These functions aren't useful anymore, so they are dropped too.
