[libvirt] [PATCH] phyp: Fix NULL dereference in phypConnectOpen
by Martin Kletzander 10 Nov '14

10 Nov '14

Coverity found out that commit cd490086 caused a possible NULL pointer dereference. This is due to the fact, that phyp_driver might be NULL (if VIR_ALLOC() fails), but connection_data, which kept the socket before the mentioned commit, could not be NULL.

[libvirt] [Bug report] - vm start failed after image snapshot rebase
by weiwei li 10 Nov '14

10 Nov '14

Hi , I hit a bug with libvirt+ qemu+kvm when doing follow steps: 1.initial status :vm = base+z(z is a snapshot) 2. call snapshotCreateXML( ): vm = base+z +z' 3. call blockRebase( ): vm = base+z''(z rebase to z') 4 .(after rebasing work done) vm shutdown and then start an error accord like this: unable to set user and group to '0:0' on '/tvm/tvm/405b9ea5-10a7-4e56-946d-58e93e2688d6/405b9ea5-10a7-4e56-946d-58e93e2688d6.vda_20141101044033': No such file or directory A second start may sucess. I debugged with gdb and found that the error message was cauesed by virSecurityDACSetSecurityDiskLabel misuse the disk chain(that is base+z +z', after rebase), and z' was deleted yet. why virSecurityDACSetSecurityDiskLabel used old disk chain after rebasing ? I finally find that In qemuProcessHandleBlockJob when rebase complete, disk chain in vm->def is updated but vm->newDef is not(when vm->newDef is not null). In shutdown( actrully in qemuProcessStop ), if vm->newDef is not null , vm->def will be replaced by vm->newDef, which contains a wrong disk chain!!! the next start will failed with above message.

[libvirt] [PATCH v2] esx: Simplify VI (vSphere) API and VMware product version handling
by Matthias Bolte 08 Nov '14

08 Nov '14

Store version numbers in this format version = 1000000 * major + 1000 * minor + micro produced by virParseVersionString instead of dedicated enums. Split the complex esxVI_ProductVersion enum into a simpler esxVI_ProductLine enum and a product version number. Relax API and product version number checks to accept everything that is equal or greater than the supported minimum version. VMware ESX went through 3 major versions and the vSphere API always stayed backward compatible. This commit assumes that this will also be true for future VMware ESX versions. Also reword error messages in esxConnectTo* to say what was expected and what was found instead (suggested by Richard W.M. Jones). --- v2: - Fix copy&paste accident that replaced hostname with conn->uri->server in esxConnectToVCenter - Fix and improve commit message src/esx/esx_driver.c | 59 +++++--------- src/esx/esx_vi.c | 215 ++++++++++++++++++++++++++------------------------- src/esx/esx_vi.h | 55 +++---------- 3 files changed, 140 insertions(+), 189 deletions(-) diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index 39784b9..64265ed 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -646,9 +646,9 @@ esxConnectToHost(esxPrivate *priv, esxVI_String *propertyNameList = NULL;

[libvirt] [PATCH] domain_conf: Use virDomainParseMemory more widely
by Michal Privoznik 07 Nov '14

07 Nov '14

As reviewing patches upstream it occurred to me, that we have two functions doing nearly the same: virDomainParseMemory which expects XML in the following format: <memory unit='MiB'>1337</memory> The other function being virDomainHugepagesParseXML expecting the following format: <someElement memory='1337' unit='MiB'/> It wouldn't matter to have two functions handle two different scenarios like this if we could only not copy code that handles 32bit arches around. So this code merges the common parts into one by inventing new @units_xpath argument to virDomainParseMemory which allows overriding the default location of @unit attribute in XML. With this change both scenarios above can be parsed with virDomainParseMemory. Sweet. Of course, everything is commented as it should be.

[libvirt] [PATCH] Transform VIR_ERROR into VIR_WARN in detect_scsi_host_caps
by Cédric Bosdonnat 07 Nov '14

If detect_scsi_host_caps reports errors but keeps libvirtd going on startup, the user is mislead by the error messages.

[libvirt] [PATCH v2] Memory : Allow specification of 'units' for numa nodes.
by Prerna Saxena 07 Nov '14

07 Nov '14

Reference : ======= v1: http://www.spinics.net/linux/fedora/libvir/msg105516.html Changes since v1: =========== 1) As suggested by Michal, a new function "virCPUNumaCellMemoryParseXML" has been introduced for neat computation of NUMA memory. 2) Patches 2 & 3 of v1 have been merged together into this cumulative patch. 3) Corresponding documentation added. >From 2199d97b88cf9eab29788fb0e440c4b0a0bb23ec Mon Sep 17 00:00:00 2001 From: Prerna Saxena <prerna(a)linux.vnet.ibm.com> Date: Mon, 3 Nov 2014 07:53:59 +0530 CPU numa topology implicitly allows memory specification in 'KiB'. Enabling this to accept the 'unit' in which memory needs to be specified. This now allows users to specify memory in units of choice, and lists the same in 'KiB' -- just like other 'memory' elements in XML. <numa> <cell cpus='0-3' memory='1024' unit='MiB' /> <cell cpus='4-7' memory='1024' unit='MiB' /> </numa> Also augment test cases to correctly model NUMA memory specification. This adds the tag 'unit="KiB"' for memory attribute in NUMA cells.

[libvirt] is there a notification when watchdog triggers?
by Chris Friesen 07 Nov '14

07 Nov '14

The libvirt.org docs say "A virtual hardware watchdog device can be added to the guest via the watchdog element....Currently libvirt does not support notification when the watchdog fires. This feature is planned for a future version of libvirt." Is that still accurate? Or does libvirt now support notifications? Chris

[libvirt] [PATCH] qemu: don't setup cpuset.mems if memory mode in numatune is 'preferred'
by Wang Rui 07 Nov '14

07 Nov '14

If the memory mode is specified as preferred, we get the following error when starting domain. error: Unable to write to '$my_cgroup_path/cpuset.mems': Device or resource busy XML is configured with numatune as follows: <numatune> <memory mode='preferred' nodeset='0'/> </numatune> If memory mode is 'preferred', cpuset.mems in cgroup shouldn't be set to 'nodeset'. I find that maybe commit 1a7be8c600905aa07ac2d78293336ba8523ad48e changes the former logic of checking mode in virDomainNumatuneGetNodeset.

[libvirt] [Patch v6 0/5] Libvirt CPU enhancements for Power KVM
by Prerna Saxena 07 Nov '14

07 Nov '14

This patch series is a collection of enhancements for PowerPC CPUs on PowerKVM. The v5 of this series has been acked. I have just rebased the patches on top of latest master and added a testcase. Series Summary: ========== Patch 1/5 : Introduce a new architecture 'ppc64le' for libvirt. Patch 2/5 : Add libvirt support for VMs running in 'compat' mode on Power KVM. Patch 3/5 : Improve PVR handling to fall back to cpu generation. Patch 4/5 : Add documentation describing compat mode usage for PowerPC guests. Patch 5/5 : Add a test case for compat mode. Detail: ==== * PowerPC has traditionally been a Big-endian architecture. However, with PowerPC ISA version 2.07, it can run in Little-endian mode as well. IBM Power8 processors, compliant with ISA 2.07 allow launching VMs in little-endian mode. This is signified by 'ppc64le' architecture. Patch 1 adds this support to libvirt, to allow running VMs based on ppc64le architecture. * Patch 2,3 tweak libvirt to correctly model PowerPC CPUs based on recent PowerKVM implementation. PowerKVM permits VMs with vcpus in the following allowed modes : i) Host native mode: where the vcpu seen in the VM belongs to the same processor generation as the host. Example: A POWER7 host, conforming to PowerISA version 2.06, will run VMs with "power7" vcpus. ii) Binary Compatibility ("compat") mode: PowerISA allows processors to run VMs in binary compatibility ("compat") mode supporting an older version of ISA. As an example: In compatibility mode, a POWER7 host can run a "power6" VM, conforming to power ISA v2.05. Similarly, a POWER8 host can run a "power7" VM conforming to PowerISA v2.06. QEMU has recently added support to explicitly denote a VM running in compatibility mode through commits 6d9412ea & 8dfa3a5e85. Henceforth, VMs of type (i) will be invoked with the QEMU invocation "-cpu host", while VMs of type (ii) will be invoked using "-cpu host, compat=power6". Now, an explicit cpu selection using "-cpu POWER6" is not valid. Instead, the recommended practice is to use the matching compat mode, if the requested cpu type differs from the host. Patches 2-3 address various aspects of this change. * Patch 2 : Adds support for generating the correct command line for QEMU. Existing xml semantics of 'host-model' are interpreted differently on PowerPc architecture to signify this type. * Patch 3 : PowerKVM vCPUs differ uniquely across generations ( such as power6, power7, power8). Each generation signifies a new PowerISA version that exhibits features unique to that generation. The higher order 16 bits of PVR denote the processor generation and the lower order 16 bits denote the cpu chip (sub)version. For all practical purposes of launching a VM, we care about the generation the vCPU will belong to, and not specifically the chip version. In fact, PowerKVM does not seek out specification of a unique chip version(such as POWER7_v2.3) for running a vCPU. This patch updates the libvirt PVR check to reflect this relationship. * Patch 4 : Documentation is added to explain functionality introduced by Patch 2. * Patch 5 : Added a test case for patch 2. Changelog: ========= v1 : https://www.redhat.com/archives/libvir-list/2014-June/msg01338.html v2 : http://www.redhat.com/archives/libvir-list/2014-October/msg00351.html v3 : http://www.mail-archive.com/libvir-list@redhat.com/msg104010.html v4 : http://www.mail-archive.com/libvir-list@redhat.com/msg104067.html v5 : http://www.mail-archive.com/libvir-list@redhat.com/msg104311.html Changes since v5: ================ * Added a new patch which introduces a test case for compat mode. * Fixed a whitespace in documentation patch #4. * Added listing for Power8e cpu model in cpu_map.xml Regards, -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India

[libvirt] [PATCH] virnetdevbandwidth: Include virutil.h
by Michal Privoznik 06 Nov '14

One of the latest patches (9a8fc3efc2470) introduced call of geteuid(). However, not all systems have the function implemented, e.g. mingw. Therefore, we fail to build on those system. The fix consist of including virutil.h which defines geteuid in needed. Sigh.

[libvirt] [PATCH] qemu: Update fsfreeze status on domain state transitions
by Michal Privoznik 06 Nov '14

06 Nov '14

As of b6d4dad1 (1.2.5) libvirt keeps track if domain disks have been frozen. However, this falls into that set of information which don't survive domain restart. Therefore, we need to clear the flag upon some state transitions. Moreover, once we clear the flag we must update the status file too.
