[libvirt] [PATCH 0/3] lxc: Implement emulator pin APIs to set/get cpuset
by Wang Rui 28 Oct '14

28 Oct '14

We can specify cpuset for a container defined with the xml like <vcpu placement='static' cpuset='0-3'> to achieve cpu isolation. It works when container is started. But there is no implements we can use to either change or get cpuset. The following patches implement the lxc driver methods for virDomainPinEmulator and virDomainGetEmulatorPinInfo. Also support container startup with emulator affinity info in xml. After these patches, we can set and get libvirt_lxc cpuset.

[libvirt] [PATCH v2 00/12] parallels: rewrite driver with parallels SDK
by Dmitry Guryanov 28 Oct '14

28 Oct '14

This patch series replaces all code, which used prlctl command to interact with parallels cloud server with calls to parallels sdk functions. The model of this driver remain almost the same - in creates a list of virDomainObj objects on connect and then functions, which returns different information get info from this list. Changes in v2: * Rebase to latest libvirt sources * Use only "parallels" prefix for functions in parallelsDriver, so that make check will pass * Update privconn->domains in case we change something from current connection. Alexander Burluka (4): parallels: get domain info with SDK parallels: handle events from parallels server parallels: added function virDomainIsActive() parallels: Add domainCreateWithFlags() function. Dmitry Guryanov (8): parallels: move IS_CT macro to parallels_utils.h parallels: move parallelsDomNotFoundError to parallels_utils.h parallels: reimplement functions, which change domain state parallels: rewrite parallelsApplyConfig with SDK parallels: create VMs and containers with sdk parallels: refactor parallelsDomainDefineXML parallels: add cdroms support parallels: implement domainUndefine and domainUndefineFlags src/parallels/parallels_driver.c | 2456 ++++++++------------------------------ src/parallels/parallels_sdk.c | 2451 +++++++++++++++++++++++++++++++++++++ src/parallels/parallels_sdk.h | 25 + src/parallels/parallels_utils.h | 11 + 4 files changed, 2957 insertions(+), 1986 deletions(-) -- 1.9.3

[libvirt] [PATCH 00/12] parallels: use SDK in parallels_driver.c
by Dmitry Guryanov 28 Oct '14

28 Oct '14

This patch series replaces all code, which used prlctl command to interact with parallels cloud server with calls to parallels sdk functions. The model of this driver remain almost the same - in creates a list of virDomainObj objects on connect and then functions, which returns different information get info from this list. But functions, which modify domains (change state, define or undefine domain) don't modify this list directly. On connect driver subscribes to event from PCS and modify the list from that events handler. So cached list of domains will be always up-to-date either after modifications from currect connection or after modifications by another tools (like prlctl) or libvirt connections. Alexander Burluka (4): parallels: get domain info with SDK parallels: handle events from parallels server parallels: added function virDomainIsActive() parallels: Add domainCreateWithFlags() function.

[libvirt] [PowerPC Patch v3] Libvirt CPU enhancements for Power KVM
by Prerna Saxena 28 Oct '14

28 Oct '14

This patch series is a collection of enhancements for PowerPC CPUs on PowerKVM. Series Summary: ========== Patch 1/3 : Introduce a new architecture 'ppc64le' for libvirt. Patch 2/3 : Add libvirt support for VMs running in 'compat' mode on Power KVM. Patch 3/3 : Optimize PVR comparison for PowerPC CPUs. 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. New xml semantics are introduced 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. 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 Changes since v2: i) CPU compat mode is now introduced under CPU mode 'host-model' as against the original proposal of using cpu mode'custom'. (Thanks for the tip, Dan.) ii) Patch 4/4 that renamed models in cpu_map.xml is dropped. Instead, CPU generations are added to cpu_map.xml as new listings. The PVR check in patch 3 of this series takes care of making the right match happen for compat mode.

[libvirt] [python v2 PATCH] Add dict check for setTime and allow pass one valid parameter
by Luyao Huang 28 Oct '14

28 Oct '14

When pass None to time, it will set guest time to 0. When pass an empty dictionary, it will report error. Allow a one-element dictionary which contains 'seconds' or 'nseconds', setting JUST seconds will do the sane thing of passing 0 for nseconds, instead of erroring out.

[libvirt] [libvirt-tck PATCH] Fix PCI device hotplug tests
by Jim Fehlig 27 Oct '14

27 Oct '14

This patch fixes a few issues noted while enabling the TCK PCI device hotplug tests. First, the call to node device dettach function misses parameters, resulting in the following failure Failed test 'detached device from host OS' at /usr/share/libvirt-tck/tests/domain/250-pci-host-hotplug.t line 90. died: Usage: Sys::Virt::NodeDevice::dettach(dev, driversv, flags=0) at /usr/share/libvirt-tck/tests/domain/250-pci-host-hotplug.t line 90. Trivally fixed by adding the missing parameters when calling node device dettach function. Second, it appears qemu needs to reach some state of initialization before host device attach/detach works properly. Currently, the test fails when detaching the device from the guest, resetting it, and reattaching it to the host Failed test 'reset the host PCI device' at /usr/share/libvirt-tck/tests/domain/250-pci-host-hotplug.t line 110. died: Sys::Virt::Error (libvirt error code: 1, message: internal error: Not resetting active device 0000:03:00.1) Failed test 'reattached device to host OS' at /usr/share/libvirt-tck/tests/domain/250-pci-host-hotplug.t line 111. died: Sys::Virt::Error (libvirt error code: 55, message: Requested operation is not valid: PCI device 0000:03:00.1 is still in use by driver QEMU, domain tck) I've found that sleeping for a bit after creating the guest allows the tests to pass.
