[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] virnuma: add notset NULL check in virNumaSetupMemoryPolicy
by Chen Fan 07 Nov '14

07 Nov '14

introduce by commit c63ef0452b, when nodeset is NULL, validation will pass in virNumaSetupMemoryPolicy, but virBitmapNextSetBit must ensure bitmap is not Null. there will cause a segmentation fault. this patch fixed it.

[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
