[libvirt] [PATCH] virQEMUCapsInitQMP: Don't dispose locked @vm
by Michal Privoznik 10 Mar '15

10 Mar '15

When creating qemu capabilities, a dummy virDomainObj is created just because our monitor code expects that. However, the object is created locked already. Then, under cleanup label, we simply unref the object which results in whole domain object to be disposed. The object lock is destroyed subsequently, but hey - it's still locked: ==24845== Thread #14's call to pthread_mutex_destroy failed ==24845== with error code 16 (EBUSY: Device or resource busy) ==24845== at 0x4C3024E: pthread_mutex_destroy (in /usr/lib64/valgrind/vgpreload_helgrind-amd64-linux.so) ==24845== by 0x531F72E: virMutexDestroy (virthread.c:83) ==24845== by 0x5302977: virObjectLockableDispose (virobject.c:237) ==24845== by 0x5302A89: virObjectUnref (virobject.c:265) ==24845== by 0x1DD37866: virQEMUCapsInitQMP (qemu_capabilities.c:3397) ==24845== by 0x1DD37CC6: virQEMUCapsNewForBinary (qemu_capabilities.c:3481) ==24845== by 0x1DD381E2: virQEMUCapsCacheLookup (qemu_capabilities.c:3609) ==24845== by 0x1DD30F8A: virQEMUCapsInitGuest (qemu_capabilities.c:744) ==24845== by 0x1DD31889: virQEMUCapsInit (qemu_capabilities.c:1020) ==24845== by 0x1DD7DD36: virQEMUDriverCreateCapabilities (qemu_conf.c:888) ==24845== by 0x1DDC57C0: qemuStateInitialize (qemu_driver.c:803) ==24845== by 0x53DC743: virStateInitialize (libvirt.c:777) ==24845== Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/qemu/qemu_capabilities.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 8193805..dce40e0 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -3394,7 +3394,10 @@ virQEMUCapsInitQMP(virQEMUCapsPtr qemuCaps, if (monpath) ignore_value(unlink(monpath)); VIR_FREE(monpath); - virObjectUnref(vm); + if (vm) { + virObjectUnlock(vm); + virObjectUnref(vm); + } virObjectUnref(xmlopt); if (pid != 0) { -- 2.0.5

[libvirt] [PATCH 0/6] Follow-up patches for IOThread API/display
by John Ferlan 10 Mar '15

10 Mar '15

Based on jtomko's review of the IOThread series and my foray into the libvirt-perl bindings, these patches make the following adjustments: Patch 1 - Found while generating the virsh iothreadpin description, the vcpupin description had a few missing words Patch 2 - While working on the libvirt-perl bindings - I found I was a bit overaggressive with my GetIOThreadsInfo interface with regard to checking ReadOnly unnecessarily Patch 3 - Adjust the IOThread CPU Affnity algorithm based on jtomko's review comments Patch 4 - Fallout because I ran the patches through my Coverity checker. Patch 5 - Similar to IOThread - adjust the GetVcpuInfo CPU Affinity algorithm for the returned cpumap Patch 5 - Similar to IOThread - adjust the GetEmulatorInfo CPU Affinity algorithm for the returned cpumap John Ferlan (6): Fix syntax for vcpupin description Remove ReadOnly check for GetIOThreadsInfo qemu: Change/Fix IOThread CPU affinity bitmap manipulation qemu: Resolve Coverity CHECKED_RETURN issue qemu: Change qemuDomainGetVcpuPinInfo bitmap manipulation qemu: Change qemuDomainGetEmulatorPinInfo bitmap manipulation src/libvirt-domain.c | 1 - src/qemu/qemu_driver.c | 177 +++++++++++++++++++++---------------------------- tools/virsh.pod | 4 +- 3 files changed, 76 insertions(+), 106 deletions(-) -- 2.1.0

[libvirt] [PATCH] qemu: don't fill in nicindexes for session mode libvirtd
by Laine Stump 10 Mar '15

10 Mar '15

Commit 4bbe1029f fixed a problem in commit f7afeddc by moving the call to virNetDevGetIndex() to a location common to all interface types (so that the niceindex array would be filled in for macvtap as well as tap interfaces), but the location was *too* common, as the original call to virNetDevGetIndex() had been in a section qualified by "if (cfg->privileged)". The result was that the "fixed" libvirtd would try to call virNetDevGetIndex() even for session mode libvirtd, and end up failing with the log message: Unable to open control socket: Operation not permitted To remedy that, this patch qualifies the call to virNetDevGetIndex() in its new location with cfg->privileged.

[libvirt] [PATCH] virnet*: Don't unlock object in dispose
by Michal Privoznik 10 Mar '15

10 Mar '15

As of bba93d40 all of our RPC objects are derived from virObjectLockable. However, during rewrite some errors sneaked in. For instance, the dispose functions to virNetClient and virNetServerClient objects were not only freeing allocated memory, but unlocking themselves. This is wrong. Object should never disappear while locked.

http://people.redhat.com/~lersek/ovmf-whitepaper-c770f8c.txt (An official Red Hat whitepaper PDF edition, for graphical displays, is in the works. As time and technical hurdles allow, both the plain text and the PDF editions shall appear under <http://www.linux-kvm.org/page/OVMF> too, replacing the stale article currently visible there.) Feedback is welcome. For public feedback, please trim the address list to <edk2-devel(a)lists.sourceforge.net> and yours truly; my intent is to spam qemu-devel, linux-efi and libvir-list just this once. (Appropriate levels of embarrassment are already being felt for spamming those.) Thanks Laszlo

[libvirt] [PATCH v2] qemu: bulk stats: implement (cpu) tune group.
by Francesco Romani 09 Mar '15

09 Mar '15

Management applications, like oVirt, may need to setup cpu quota limits to enforce QoS for domains. For this purpose, management applications also need to check how domains are behaving with respect to CPU quota. This data is available using the virDomainGetSchedulerParameters API. This patch adds a new group to bulk stats API to obtain the same information.

[libvirt] [PATCH] sanlock: Don't spam logs with "target pid not found"
by Jiri Denemark 09 Mar '15

09 Mar '15

Commit v1.2.4-52-gda879e5 fixed issues with domains started before sanlock driver was enabled by checking whether a running domain is registered with sanlock and if it's not, sanlock driver is basically ignored for the domain. However, it was checking this even for domain which has just been started and no sanlock_* API was called for them yet. This results in cmd 9 target pid 2135544 not found error messages to appear in sanlock.log whenever we start a new domain. This patch avoids this useless check for freshly started domains.

[libvirt] [PATCH] tests: fix qemuxml2argvtest to be arch independent
by Pavel Hrdina 09 Mar '15

09 Mar '15

Commit 5aee81a0 introduced a new test for disk-serial. The test fails on i686 arch because there is no need to add "-cpu qemu32" to command line. To fix the test update emulator in XML to "/usr/bin/qemu" so we don't add the "-cpu qemu32" to command while running the test on i686 or x86_64 host.

[libvirt] [PATCH] libvirt-domain.h: changing some unsigned int parameters to the respective enum type.
by Julio Faracco 09 Mar '15

09 Mar '15

Recently, some code were cleaned ups. Now, some parameters are being converted to its respective enum type. For example, there are many functions that are using int or unsigned int types instead enum types. So, this kind of cleaning up can be necessary.

[libvirt] [RFC PATCH v2 0/4] Enable spapr-pci-vfio-host-bridge controllers for VFIO passthrough support
by Shivaprasad G Bhat 09 Mar '15

09 Mar '15

The following series of patches enable spapr-pci-vfio-host-bridge controllers on PPC64-pseries machine which is required for supporting host device passthrough using VFIO. There were some initial enablement work on the same at http://www.redhat.com/archives/libvir-list/2013-September/msg00838.html. On pseries(ppc64), the vfio host devices(will refer as hostdevs here on) cannot be assigned to the default emulated pci-host-bus(phb) controller(like the default pci.0). The hostdevs goto spapr-pci-vfio-host-bridge. The hostdevs belonging to the same iommu group share the same spapr-pci-vfio-host-bridge. Henceforth, new spapr-pci-host-bridge needs to be added for every hostdev belonging to any new iommu group. The hostdevs should be attached to their respective spapr-pci-vfio-host-bridge. Libvirt today adds all the devices to the default pci domain. The patch series take care to add the new controller. A new pci domain in the guest per controller is created. The hostdevs get their pci address in the respective domain. The patch series taskes care of device addressing in vfio hostdevs, SR-IOV interfaces and network interfaces from SRIOV virtual function pools.

[libvirt] ANNOUNCE: Oz 0.13.0 release
by Chris Lalancette 07 Mar '15

07 Mar '15

All, I'm pleased to announce release 0.13.0 of Oz. Oz is a program for doing automated installation of guest operating systems with limited input from the user. Release 0.13.0 is a bugfix and feature release for Oz. Some of the highlights between Oz 0.12.0 and 0.13.0 are: - For Fedora, if the user specifies a version, but that isn't supported yet, try the last supported version (in this case), as that will often work. - Fix a regression where we forgot to force the qcow2 image type - Allow installs that use more than one installation device - Add support for RHEL 6.5 - Rename OEL-6 to OL-6 - Add support for Ubuntu 14.04 - Add Windows 8.1 support - Add CentOS-7 support - Add the ability to specify kernel parameters in the TDL - Make sure to remove dhcp leases from guests after the install - Fix support for FreeBSD - Add in support for TDL "precommands"; these are commands that are run *before* package installation - Fix up file locking - Add support for RHEL 5.11 - Remove Ubuntu ssh keys at the end of installation - Add support for Ubuntu 14.10 - Add support for XInclude, for merging various TDLs together - Add Fedora 21 support - Add support for ppc64 and ppc64le A tarball and zipfile of this release is available on the Github releases page: https://github.com/clalancette/oz/releases .

[libvirt] [PATCH v4 0/9] Introduce display of IOThreads Information
by John Ferlan 06 Mar '15

06 Mar '15

v3: http://www.redhat.com/archives/libvir-list/2015-February/msg00593.html Changes since v3: (from code reviews) - Updated to use 1.2.14 not 1.2.13 - Change struct from virDomainIOThreadsInfo to virDomainIOThreadInfo - Remove the resources and nresources from virDomainIOThreadInfo and of course all associated code as well as changing the remote struct from iothreads_* to iothread_ - Create separate routines for virDomainGetIOThreadsInfo, virDomainGetIOThreadPin, and virDomainPinIOThread... and of course all the accompanying code - Use EnterMonitor instead of EnterMonitorAsync Still need to generate a v3 of the python code, but I'll wait for this to be reviewed first. John Ferlan (9): Implement public API for virDomainGetIOThreadsInfo remote: Implement the remote plumbing for virDomainGetIOThreadsInfo qemu: Implement the qemu driver fetch for IOThreads virsh: Add 'iothreadsinfo' command Implement public API for getting/setting specific IOThread pinning remote: Plumbing for getting/setting specific IOThread pinning domain: Introduce virDomainIOThreadsPin{Add|Del} qemu: Add support to get/set specific IOThread pinning data virsh: Add iothreadpin command daemon/remote.c | 123 ++++++++- include/libvirt/libvirt-domain.h | 41 ++- src/conf/domain_conf.c | 64 +++++ src/conf/domain_conf.h | 10 + src/driver-hypervisor.h | 24 +- src/libvirt-domain.c | 227 ++++++++++++++++- src/libvirt_private.syms | 2 + src/libvirt_public.syms | 8 + src/qemu/qemu_driver.c | 526 +++++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 143 ++++++++++- src/remote/remote_protocol.x | 61 ++++- src/remote_protocol-structs | 43 ++++ src/rpc/gendispatch.pl | 2 + tools/virsh-domain.c | 216 ++++++++++++++++ tools/virsh.pod | 38 +++ 15 files changed, 1521 insertions(+), 7 deletions(-) -- 2.1.0

[libvirt] ANNOUNCE: Libvirt Designer version 0.0.2 released
by Daniel P. Berrange 06 Mar '15

06 Mar '15

I'm pleased to announce the second release of the libvirt designer library, version 0.0.2 ftp://ftp.libvirt.org/libvirt/designer/libvirt-designer-0.0.2.tar.gz The release is signed ftp://ftp.libvirt.org/libvirt/designer/libvirt-designer-0.0.2.tar.gz.asc with the GPG key having the fingerprint DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) In this release: - Bumped soname & version for ABI change - Remove use of deprecated libosinfo calls - Fix various memory leaks - Treat errors loading the libosinfo DB as non-fatal as some data may be successfully loaded - Improve building of libosinfo short-id from libvirt capabilities information - Expose the libosinfo DB object via a property on the domain object - Don't set PKG_CONFIG_PATH for g-ir-scanner - Auto-generate list of AUTHORS - Avoid redefining _FORTIFY_SOURCE macro - Fix & add gtk-doc introspection annotation - Add Vala APi binding - Add support for floppy & CDROM devices - Use libvirt style libtool versioning csheme - Add API to set list of installed drivers - Add API for querying supported devices - Remove many bogus assumptions in disk bus handling - Populate clock settings, input devices & console - Add API for enabling sound devices - Add AP ifor enabling choice of graphics backends - Add SPICE agent if using SPICE - Add API for enabling USB redirection - Add API for enabling smartcard devices - Add API for enabling video devices - Import latest compiler warnings from gnulib - Avoid using deprecated libvirt-gconfig APIs - Rename virtxml binary to virt-designer - Add API for choosing network backend type - Add further test cases for validing domain builder - Always build test programs The libvirt-designer library builds on top of the libvirt-gconfig and libosinfo libraries, to provide an API that assists applications in building guest domain configurations based on libosinfo policy. The intention is that it be usable from applications such as virt-manager and GNOME boxes which currently duplicate this kind of policy based configuration logic between them. It is still at an early experimental stage of development so it is liable to have further ABI incompatible changes in future releases, which will require recompiling applications and possibly source level changes too. Thanks to all the people who contributed towards this new release.

[libvirt] [PATCH v2 0/3] unify memtune value representation in libvirt
by Pavel Hrdina 06 Mar '15

06 Mar '15

The first patch rewrites virsh memtune command to accept 0 as valid value instead of ignoring it. In the second patch I'll introduce a simple helper to crop the *_limit values to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED as its used several times while reading values from cgroups and also a helper to check whether the memory limits are set or not. The last patch actually changes the internal representation of unlimited memtune settings. More detailed description is in commit message. My motivation to change it completely is to prevent future bugs with those limits.

[libvirt] [PATCH v8 0/4] Introduce API to query IP addresses for given domain
by Nehal J Wani 06 Mar '15

06 Mar '15

This feature has been requested for a very long time. Since qemu guest agent and leaseshelper give us reliable results, now the wait is over. The RFC was first proposed by Michal Privoznik: http://www.redhat.com/archives/libvir-list/2012-February/msg00437.html A patch was submitted, using structs: https://www.redhat.com/archives/libvir-list/2012-June/msg00220.html Another patch was submitted, using XML: https://www.redhat.com/archives/libvir-list/2012-June/msg00904.html Neither of the patches were accepted, probably due to lack of extensibility and usability. Hence, we thought of using virTypedParameters for reporting list of interfaces along with their MAC address and IP addresses. The RFC can be found here: https://www.redhat.com/archives/libvir-list/2013-July/msg00084.html The idea of extensibility was rejected and rendered out of scope of libvirt. Hence, we were back to structs. This API is called virDomainInterfaceAddresses which returns a dynamically allocated array of virDomainInterface struct. The great disadvantage is once this gets released, it's written in stone and we cannot change or add an item into it. The virsh CLI supports two methods: * Return information (list of all associated interfaces with MAC address and IP addresses) of all of the domain interfaces by default (if no interface name is provided) * Return information for the specified interface (if an interface name is provided) v8: * qemuDomainInterfaceAddresses: redo logic related to flags * Make sure that NIC(s) on guest is/are using libvirt virtual network before querying leaseshelper * domifaddr: change --network option from VSH_OT_DATA to VSH_OT_STRING v7: * Enable support for DHCP lease file parsing method * http://www.redhat.com/archives/libvir-list/2014-December/msg00866.html v6: * Inclusion of flags, readonly check for guest agent connection * Correction of memory leaks, other small nits. * https://www.redhat.com/archives/libvir-list/2013-September/msg00350.html v5: * s/virDomainInterfacesAddresses/virDomainInterfaceAddresses. * Case for IP aliasing handled using virHashTable. * New test cases added, involving multiple and 0 IP addresse(s) per interface. * IP prefix changed from int to unsigned int. * Changes to practice libvirt habits. * https://www.redhat.com/archives/libvir-list/2013-September/msg00003.html v4: * Various style nits, indentation errors, memory leaks fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg01265.html v3: * Upper bounds to number of interfaces and addresses per interface introduced. * Change from array of structs to array of pointers * ifaces_count moved from function argument to return value * Changes in variable names * Test cases added for qemuAgentGetInterfaces. * https://www.redhat.com/archives/libvir-list/2013-August/msg01215.html v2: * Logical errors, memory leaks and few other errors fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg00631.html v1: * http://www.redhat.com/archives/libvir-list/2013-July/msg01553.html Nehal J Wani (4): domifaddr: Implement the public APIs domifaddr: Implement the remote protocol domifaddr: Implement the API for qemu domifaddr: Add virsh support daemon/remote.c | 134 ++++++++++++++++++++++++++ include/libvirt/libvirt-domain.h | 27 ++++++ src/driver-hypervisor.h | 5 + src/libvirt-domain.c | 129 +++++++++++++++++++++++++ src/libvirt_public.syms | 6 ++ src/qemu/qemu_agent.c | 202 +++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 4 + src/qemu/qemu_driver.c | 173 +++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 100 +++++++++++++++++++ src/remote/remote_protocol.x | 36 ++++++- src/remote_protocol-structs | 24 +++++ tests/qemuagenttest.c | 188 ++++++++++++++++++++++++++++++++++++ tools/virsh-domain-monitor.c | 141 +++++++++++++++++++++++++++ tools/virsh.pod | 16 ++++ 14 files changed, 1184 insertions(+), 1 deletion(-) -- 2.1.0

I read this in the context of direct device assignment: "All of the guest's memory must kept permanently in memory. This is because the guest may program the device with any address in its address space and the hypervisor has no way of handling a DMA page fault" is it still true? Thanks, Regards,

[libvirt] [PATCH v3 0/9] Introduce display of IOThreads Information
by John Ferlan 05 Mar '15

05 Mar '15

v2 here: http://www.redhat.com/archives/libvir-list/2015-February/msg00562.html Changes over v2: Patches 1-4 * Add "resources" and "nresources" in order to return the resources that are using an IOThread * Fixed memory leak - neglected to free the qemuMonitorIOThreadsInfoPtr 'iothreads' in patch 3 Patches 5-9 (NEW) * Patches 5 & 6 implement the API/remote protocol for virDomainSetIOThreads * Patch 7 implements a couple of helper function - copies of existing vcpupin functions * Patch 8 implements the qemu backend qemuDomainSetIOThreads in order to allow setting IOThread pin data either for live or config. Heavily lifted from existing vcpu code * Patch 9 implements the virsh command options in order to set the pinning on a specific thread. As a side effect/benefit one can now display just one IOThread if so desired. All the changes are sufficient to satisfy the following bz: https://bugzilla.redhat.com/show_bug.cgi?id=1135491 John Ferlan (9): Implement public API for virDomainGetIOThreadsInfo remote: Implement the remote plumbing for virDomainGetIOThreadsInfo qemu: Implement the qemu driver fetch for IOThreads virsh: Add 'iothreads' command Implement public API for virDomainSetIOThreads remote: Implement remote plumbing for virDomainSetIOThreads domain: Introduce virDomainIOThreadsPin{Add|Del} qemu: Add qemuDomainSetIOThreads virsh: Allow setting of the iothread pin daemon/remote.c | 99 +++++++- include/libvirt/libvirt-domain.h | 48 +++- src/conf/domain_conf.c | 64 +++++ src/conf/domain_conf.h | 10 + src/driver-hypervisor.h | 16 +- src/libvirt-domain.c | 149 ++++++++++- src/libvirt_private.syms | 2 + src/libvirt_public.syms | 7 + src/qemu/qemu_driver.c | 519 +++++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 94 ++++++- src/remote/remote_protocol.x | 48 +++- src/remote_protocol-structs | 33 +++ src/rpc/gendispatch.pl | 1 + tools/virsh-domain.c | 154 ++++++++++++ tools/virsh.pod | 20 ++ 15 files changed, 1257 insertions(+), 7 deletions(-) -- 2.1.0

[libvirt] [PATCH] domain_conf: Format <pvpanic/> without address correctly
by Michal Privoznik 05 Mar '15

05 Mar '15

We have something like pvpanic device. However, in some cases it does not have any address assigned, in which case we produce this ugly XML (still valid though): <devices> <emulator>/usr/bin/qemu</emulator> ... <panic> </panic> </devices> Lets format "<pvpanic/>" instead.

[libvirt] [PATCH 0/3] unify memtune value representation in libvirt
by Pavel Hrdina 05 Mar '15

05 Mar '15

The first patch rewrites virsh memtune command to accept 0 as valid value instead of ignoring it. In the second patch I'll introduce a simple helper to crop the *_limit values to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED as its used several times while reading values from cgroups. The last patch actually changes the internal representation of unlimited memtune settings. More detailed description is in commit message. My motivation to change it completely is to prevent future bugs with those limits.

[libvirt] [PATCH v2] qemu: Allow spaces in disk serial

https://bugzilla.redhat.com/show_bug.cgi?id=1195660 There's been a bug report appearing on the qemu-devel list, that libvirt is unable to pass spaces in disk serial number [1]. Not only our RNG schema forbids that, the code is not prepared either. However, with a bit of escaping (if needed) we can allow spaces there. 1: https://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04041.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- diff to v1: - Switch from virBufferEscapeShell to virBufferEscape docs/schemas/domaincommon.rng | 2 +- src/qemu/qemu_command.c | 5 ++-- .../qemuxml2argvdata/qemuxml2argv-disk-serial.args | 7 ++++++ .../qemuxml2argvdata/qemuxml2argv-disk-serial.xml | 27 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 5 ++++ 5 files changed, 43 insertions(+), 3 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index f41ca43..09bd921 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -5067,7 +5067,7 @@ </define> <define name="diskSerial"> <data type="string"> - <param name="pattern">[A-Za-z0-9_\.\+\-]+</param> + <param name="pattern">[A-Za-z0-9_\.\+\- ]+</param> </data> </define> <define name="bridgeMode"> diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index fb3d5ab..25b6499 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -2633,7 +2633,7 @@ qemuBuildIoEventFdStr(virBufferPtr buf, } #define QEMU_SERIAL_PARAM_ACCEPTED_CHARS \ - "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_" + "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_ " static int qemuSafeSerialParamValue(const char *value) @@ -3616,7 +3616,8 @@ qemuBuildDriveStr(virConnectPtr conn, virQEMUCapsGet(qemuCaps, QEMU_CAPS_DRIVE_SERIAL)) { if (qemuSafeSerialParamValue(disk->serial) < 0) goto error; - virBufferAsprintf(&opt, ",serial=%s", disk->serial); + virBufferAddLit(&opt, ",serial="); + virBufferEscape(&opt, '\\', " ", "%s", disk->serial); } if (disk->cachemode) { diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args new file mode 100644 index 0000000..794b94b --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.args @@ -0,0 +1,7 @@ +LC_ALL=C PATH=/bin HOME=/home/test USER=test LOGNAME=test QEMU_AUDIO_DRV=none \ +/usr/libexec/qemu-kvm -S -M pc -cpu qemu32 -m 214 -smp 1 -nographic -nodefaults \ +-monitor unix:/tmp/test-monitor,server,nowait -no-acpi -boot c -usb \ +-drive 'file=/dev/HostVG/QEMUGuest1,if=none,\ +id=drive-ide0-0-1,serial=\ \ WD-WMAP9A966149' \ +-device ide-drive,bus=ide.0,unit=1,drive=drive-ide0-0-1,id=ide0-0-1 \ +-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml new file mode 100644 index 0000000..0fe75f3 --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-serial.xml @@ -0,0 +1,27 @@ +<domain type='kvm'> + <name>QEMUGuest1</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219136</memory> + <currentMemory unit='KiB'>219136</currentMemory> + <vcpu placement='static'>1</vcpu> + <os> + <type arch='i686' machine='pc'>hvm</type> + <boot dev='hd'/> + </os> + <clock offset='utc'/> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>destroy</on_crash> + <devices> + <emulator>/usr/libexec/qemu-kvm</emulator> + <disk type='block' device='disk'> + <source dev='/dev/HostVG/QEMUGuest1'/> + <target dev='hda' bus='ide'/> + <serial> WD-WMAP9A966149</serial> + <address type='drive' controller='0' bus='0' target='0' unit='1'/> + </disk> + <controller type='usb' index='0'/> + <controller type='ide' index='0'/> + <memballoon model='virtio'/> + </devices> +</domain> diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 16f325e..3032d1b 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -904,6 +904,11 @@ mymain(void) QEMU_CAPS_DEVICE, QEMU_CAPS_SCSI_BLOCK, QEMU_CAPS_VIRTIO_BLK_SG_IO, QEMU_CAPS_SCSI_LSI, QEMU_CAPS_VIRTIO_SCSI); + DO_TEST("disk-serial", + QEMU_CAPS_KVM, + QEMU_CAPS_DEVICE, + QEMU_CAPS_DRIVE, + QEMU_CAPS_DRIVE_SERIAL); DO_TEST("graphics-vnc", QEMU_CAPS_VNC); DO_TEST("graphics-vnc-socket", QEMU_CAPS_VNC); -- 2.0.5

[libvirt] [PATCH v1 00/31] Drop network driver lock
by Michal Privoznik 05 Mar '15

The patchset starts slowly, with small patches, and small changes, accelerating towards the end, with big changes. I know that network driver is not used as intensely as domain drivers, but hey, if we remove 100 lines (and substitute some others) we get fine grained locking! And cleaner code, of course. Oh, and this is meant for next release, obviously :) Michal Privoznik (31): networkLookupByUUID: Improve error message bridge_driver: Don't check network active unlocked testNetworkUpdate: Unlock network at the end networkGetNetworkAddress: Drop empty 'error' label virNetworkObjIsDuplicate: s/@doms/@nets/ virNetworkObjListFree: Accept NULL virNetworkObjListExport: Pass virNetworkObjListPtr test_driver: s/virNetworkObjList/virNetworkObjListPtr/ parallels: s/virNetworkObjList/virNetworkObjListPtr/ bridge_driver: s/virNetworkObjList/virNetworkObjListPtr/ conf: s/virNetworkFindByUUID/virNetworkObjFindByUUID/ conf: s/virNetworkFindByUUID/virNetworkObjFindByUUID/ network_conf: Introduce virNetworkObjListForEach network_conf: Introduce virNetworkObjListGetNames network_conf: Introduce virNetworkObjListNumOfNetworks bridge_driver: Adapt to new virNetworkObjList accessors test_driver: Adapt to new virNetworkObjList accessors parallels_network: Adapt to new virNetworkObjList accessors network_conf: Turn virNetworkObjList into virObject network_conf: Turn struct _virNetworkObjList private network_conf: Make virNetworkObj actually virObject virNetworkObjList: Derive from virObjectLockableClass network_conf: Introduce virNetworkObjEndAPI bridge_driver: Use virNetworkObjEndAPI test_driver: Use virNetworkObjEndAPI parallels_network: Use virNetworkObjEndAPI virNetworkObjListPtr: Make APIs self-locking virNetworkObjFindBy*: Return an reference to found object bridge_driver: Drop networkDriverLock() from almost everywhere test_driver: Drop testDriverLock() from almost everywhere parallels_network: Drop parallelsDriverLock() from everywhere. cfg.mk | 3 - src/conf/network_conf.c | 372 +++++++++++++++++++------- src/conf/network_conf.h | 51 ++-- src/libvirt_private.syms | 14 +- src/network/bridge_driver.c | 502 ++++++++++++++--------------------- src/network/bridge_driver_platform.h | 2 +- src/parallels/parallels_driver.c | 5 +- src/parallels/parallels_network.c | 144 +++------- src/parallels/parallels_utils.h | 2 +- src/test/test_driver.c | 223 ++++------------ tests/networkxml2conftest.c | 4 +- tests/objectlocking.ml | 2 - 12 files changed, 612 insertions(+), 712 deletions(-) -- 2.0.5

[libvirt] [PATCH v2] qemu: snapshot: remove the redundant 'if' check
by Shanzhi Yu 05 Mar '15

05 Mar '15

[libvirt] [PATCH] parallels: Cleanup partly opened drivers on connect open failure
by Michal Privoznik 04 Mar '15

04 Mar '15

Well, the parallelsConnectOpen() joins several sub-driver openings into one big if condition. If any of sub-driver fails to open, the whole API finishes immediately. The problem is, sub-drivers may have left some memory allocated. Fortunately, we have a free function for that: parallelsConnectClose(). This is, however, not prepared for partially allocated driver structure. So, prepare the free function for it and call it at the right place, in the if body.

[libvirt] overlayfs support to lxc driver
by Vasiliy Tolstov 04 Mar '15

04 Mar '15

Hello. I'm interesting in implementing overlayfs support to lxc libvirt driver. As i see i simply can utilize filesystem type='template' for this usage. In case os template fs i need to mount with lowerdir /var/lib/libvirt/filesystems/template to /var/lib/libvirt/filesystems/name But i have problem: overlayfs fs need upperdir that store differences and mountpoint that used by clients. In case of libvirt usage - upperdir need to be places in /var/lib/libvirt/filesystems, but where i can put mountpoint dir ? /var/run/libvirt or in /tmp/libvirt-XXXXX ? Also what is the preferred way to integrate overlayfs support to libvirt? I can addd mount type to filesystem type='mount' or use (like now) template type. What is the preferred way?

However we only use this pidfile when we start the vm, and won't use it after it start, so this is not a big deal. But it is strange when vm is offline but pidfile still exist, so remove vmname.pid in state dir (maybe /run/libvirt/qemu/)when priv->pidfile is NULL.

[libvirt] [PATCH] qemuProcessReconnect: Fill in pid file path
by Michal Privoznik 03 Mar '15

03 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1197600 So, libvirt uses pid file to track pid of started qemus. Whenever a domain is started, its pid is put into corresponding pid file. The pid file path is generated based on domain name and stored into domain object internals. However, it's not stored in the status XML and therefore lost on daemon restarts.

[libvirt] [PATCH v3 0/9] qemu: Add quorum support to libvirt
by Matthias Gatto 03 Mar '15

03 Mar '15

The purpose of these patches is to introduce quorum for libvirt I've try to follow this proposal: http://www.redhat.com/archives/libvir-list/2014-May/msg00533.html This feature ask for 6 task: 1) Allow a _virStorageSource to contain more than one backing store. Because all the actual libvirt code use the backingStore field as a pointer and we needs want to change that, I've decide to encapsulate the backingStore field to simplifie the array manipulation. 2) Add the missing field a quorum need in _virStorageSource and the VIR_STORAGE_TYPE_QUORUM and VIR_STORAGE_FILE_QUORUM in their respectives enums. 3) Parse and format the xml Because a quorum allows to have more than one backing store at the same level we need to change virDomainDiskDefFormat and virDomainDiskDefParseXML to call virDomainDiskBackingStoreFormat and virDomainDiskBackingStoreParse in a loop. virDomainDiskBackingStoreFormat and virDomainDiskBackingStoreParse can call themself recursively in a loop because a quorum can contain another quorum 4) Add nodename We need to add nodename support in _virStorageSource because qemu use them for their child. 5) Build qemu string As for the xml, we have to call the function which create quorum recursively. But this task have the problem explained here: http://www.redhat.com/archives/libvir-list/2014-October/msg00529.html The _virStorageSource missing some informations that can be passed to a child, and therefore this version of quorum is incomplet. 6) Allow to hotplug/change a disk in a quorum This part is not present in these patches because for this task we have to use blockdev-add, and currently libvirt use device_add for hotpluging that doesn't allow to hotplug quorum childs. There is 3 way to handle this problem: 1) create a virDomainBlockDevAdd function in libvirt witch call blockdev-add. 2) use blockdev-add instead of device_add in qemuMonitorJSONAddDevice 3) write a hack which uses blockdev-add when only attaching quorum (but i'm pretty sure this solution is not the good one) V2: -Rebase on master -Add Documentation V3: -Transforme the backingStore field in virStorageSource into an array of pointer instead of a pointer -Modify virStorageSourceSetBackingStore to allow it to expand the backingStore size.

[libvirt] [PATCH] schema: Fix interface link state schema
by Peter Krempa 03 Mar '15

03 Mar '15

In commit edd1295e1da6bfe8e4e257e5fbfad71ac0bf7c87 I've introduced an XML element that allows to configure state of the network interface link. Somehow the RNG schema hunk ended up in a weird place in the network schema definition. Move it to the right place and add a test case. Note that the link state is set up via the monitor at VM startup so I originally didn't think of adding a test case.

[libvirt] [PATCH 0/2] Update find-storage-pool-source[-as] man page
by John Ferlan 03 Mar '15

03 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=921426 The first patch is just a change to the error message. As it turns out only the host is necessary to find iSCSI targets. I have to assume over time adjustments to the code made the need to provide the name obsolete, but I did not research exactly which change may have done that... The second patch is a virsh man page change to describe the functionality based on how the code works today. It's perhaps "of interest" that the rbd and sheepdog backends provide to means to find all possible sources. I also suppose zfs could use something, but I don't build with zfs.

[libvirt] [PATCH 0/2] Disallow the usage of the same target dev value
by John Ferlan 03 Mar '15

03 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1142631 Patch 1 was found when adjusting the bz to get the disk by the pool source instead of directly by file attribute. When using domblklist, the source wasn't displayed. Followed the model of the iscsi '@name' and added '@volume' (eg, <source pool='default' volume='test-1g.img'/>) Patch 2 started as a simple (hah!) double loop looking for duplicate dst strings. I chose a separate API called before qemuCheckDiskConfig since it's more of a "common" check that could be used by other drivers as opposed to the perhaps more specific single disk checks made. Besides I didn't want a ndisk factorial checking algorithm each time a disk was checked for something that could be checked once. With the code in place, running make check tripped over a number of existing tests that duplicated that '<target dev=...' value, so I fixed those. Of interest for a few was that the test would duplicate the supposedly unique alias id - those are cleaned up as well as a byproduct of the changes.

[libvirt] [PATCH] qemu: Don't crash in qemuDomainOpenChannel()
by Martin Kletzander 02 Mar '15

02 Mar '15

The problem here was that when opening a channel, we were checking whether the channel given is alias (can't be NULL for running domain) or it's name, which can be NULL (for example with spicevmc). In case of such domain qemuDomainOpenChannel() made the daemon crash. STREQ_NULLABLE() is safe to use since the code in question is wrapped in "if (name)" and is more readable, so use that instead of checking for non-NULL "vm->def->channels[i]->target.name".

[libvirt] [PATCH] docs: add a note that attr 'managed' is only used by PCI devices

Our documentation isn't 100% clear about hostdev 'managed' attribute usage, because it only makes sense to use it with PCI devices, yet we format this attribute to all hostdev devices. By adding a note into the docs, we can possibly avoid confusion from customer's side and also avoid a solution using ternary logic.

[libvirt] new warning from ar on rawhide systems
by Eric Blake 28 Feb '15

28 Feb '15

When compiling libvirt (and probably other packages) on Fedora rawhide systems, I'm seeing a new warning message on every link line. # rpm -q libtool gcc binutils libtool-2.4.6-1.fc23.x86_64 gcc-5.0.0-0.16.fc23.x86_64 binutils-2.25-6.fc23.x86_64 For an example of the warning during a 'make V=1': > libtool: link: rm -fr .libs/libvirt_driver_qemu_impl.a .libs/libvirt_driver_qemu_impl.la > libtool: link: ar cru .libs/libvirt_driver_qemu_impl.a qemu/.libs/libvirt_driver_qemu_impl_la-qemu_agent.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_capabilities.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_command.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_domain.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_cgroup.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_hostdev.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_hotplug.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_conf.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_process.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_migration.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_monitor.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_monitor_text.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_monitor_json.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_driver.o qemu/.libs/libvirt_driver_qemu_impl_la-qemu_interface.o > ar: `u' modifier ignored since `D' is the default (see `U') > libtool: link: ranlib .libs/libvirt_driver_qemu_impl.a Reading 'man ar', it looks like a relatively new binutils invention, one that Fedora chose to flip on by default, but also one that might be worth using even when ar is built with 'U' rather than 'D' as the default: > D Operate in deterministic mode. When adding files and the archive > index use zero for UIDs, GIDs, timestamps, and use consistent file > modes for all files. When this option is used, if ar is used with > identical options and identical input files, multiple runs will > create identical output files regardless of the input files' > owners, groups, file modes, or modification times. > > If binutils was configured with --enable-deterministic-archives, > then this mode is on by default. It can be disabled with the U > modifier, below. Is it worth teaching libtool to change ARFLAGS to be 'crD' instead of 'cru' when it is detected that ar is new enough to support deterministic libraries, in part to shut up the warning message being printed on every single libtool link line? (Note that I would explicitly include 'D', because even though Fedora chose to make 'D' the default, other distros may choose to make 'U' the default). Or conversely, do we want ARFLAGS to be 'cruU', to force non-deterministic mode, since any speedups made possible by timestamp comparison ('u') are only possible in non-deterministic mode? Does the use of 'u' buy us much measurable time when repeatedly and incrementally linking large libraries, where the new 'D' mode is forced to link everything instead of just the new inputs? And of course there's the question of how easy is it to detect that ar is new enough to understand the 'D'/'U' dichotomy? Is this something I should redirect to automake instead of libtool? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH 0/3] Only talk to qemu guest agent when the domain is running

Previously, only virDomainObjIsActive() was used to check domain liveness. This includes states like 'VIR_DOMAIN_PMSUSPENDED', where QEMU is running, but the guest is not. Explicitly check the state against VIR_DOMAIN_RUNNING and refuse to communicate with the agent if it does not match. https://bugzilla.redhat.com/show_bug.cgi?id=872424 Ján Tomko (3): Check for qemu guest agent availability after getting the job Pass virDomainObjPtr to qemuDomainAgentAvailable Check if domain is running in qemuDomainAgentIsAvailable src/qemu/qemu_domain.c | 11 ++++++++++- src/qemu/qemu_domain.h | 2 +- src/qemu/qemu_driver.c | 49 +++++++++++++++++++++++++------------------------ 3 files changed, 36 insertions(+), 26 deletions(-) -- 2.0.5

No, I don't think so. The related code is int virFirewallApply(virFirewallPtr firewall) { size_t i, j; int ret = -1; virMutexLock(&ruleLock); if (!firewall || firewall->err == ENOMEM) { virReportOOMError(); goto cleanup; ... } I suspect 'firewall' is null, so OOM error is reported and the function returns -1.

[libvirt] [PATCH] qemu: forbid large value wraparound in balloon period collection
by Erik Skultety 27 Feb '15

27 Feb '15

We do parse and represent period collection as unsigned int in our internal structures, however commit d5c67e7f4523450023b89b69c16472582c85eeaf converts this to int, thus wrapping around inputs greater than INT_MAX which results in an error from QEMU. This patch adds a check into QEMU driver, because period attribute is only supported by QEMU.

[libvirt] Adding timestamps for all emulator output
by Andrey Korolyov 26 Feb '15

26 Feb '15

Hello, I think it would be useful if libvirt will be able to prefix all messages from emulator pipes with the date stamping, for example I am trying to catch very rare and non-fatal race with virtio-serial-bus: Guest failure in adding device virtio-serial0.0 which is specific to the Windows guests on qemu-kvm. I have supporting infrastructure which can tell me exact times for every action upon this VM, but as bug is not frequent, the continuous monitoring looks like an overkill for a desired goal - find a correlation between emulator event and message from stderr. Patching emulator itself is barely an option, as it is ugly, requires refresh of the running code via loopback migration and completely non-universal, as every hypervisor should be modified seperately. I`d highly appreciate positive consideration for such functionality addition or can write a patch shortly, if needed. Thanks!

[libvirt] [PATCH] util: do not take it as wrong if no PortData is found while getting migrateData
by Zhang Bo 26 Feb '15

26 Feb '15

The function virNetDevOpenvswitchGetMigrateData() uses the cmd ovs-vsctl to get portdata. If no portdata is available, rather than failure in running the cmd, we think we should just print a warning message here, rather than taking it as wrong, because PortData is just optional for an ovs interface. If we take it as wrong anyway, in function qemuMigrationBakeCookie() it will terminate in the middle, and cookies such as NBD would not be baked, further more errors would happen, such as nbd ports get overflowed, etc. Thus, we add an if branch in virNetDevOpenvswitchGetMigrateData() to just warn if portdata is unavailable.

[libvirt] Entering freeze for libvirt-1.2.13
by Daniel Veillard 26 Feb '15

26 Feb '15

As suggested yesterday, and hearing no opposition, I have just tagged Redlease Candidate 1 for libvirt-1.2.13 in git and signed tarballs and rpms for it available at the usual place: ftp://libvirt.org/libvirt/ Based on my own but minimal testing this seems to work, but obviously please give it a try so we can squash bugs and portability issues in time. A candidate release 2 on Thursday and a final 1.2.13 release next Monday is the schedule assumeing no major issue is found, so please give it a test !
