[libvirt] [PATCH 0/6] lxc: Add suport to virConnectGetAllDomainStats().
by Julio Faracco 12 Mar '19

12 Mar '19

This series has a collection of new methods to enable support for virConnectGetAllDomainStats() to LXC driver. The only difference is Disk Stats. It needs to consider only the host file system operations or any other block device as a external disk or partition. Julio Faracco (6): lxc: Introduce method lxcConnectGetAllDomainStats(). lxc: Introduce method lxcDomainGetStats(). lxc: Introduce method lxcDomainGetStatsCpu(). lxc: Introduce method lxcDomainGetStatsState(). lxc: Introduce method lxcDomainGetBlockStats(). lxc: Introduce method lxcDomainGetBalloonStats(). src/lxc/lxc_driver.c | 357 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 357 insertions(+) -- 2.19.1

[libvirt] [PATCH v3 0/4] PPC64 support for NVIDIA V100 GPU with NVLink2 passthrough
by Daniel Henrique Barboza 12 Mar '19

12 Mar '19

This series includes Libvirt support for a new QEMU feature for the spapr (PPC64) machine, NVIDIA V100 + P9 passthrough. Refer to [1] for the version 3 of this feature (same version used as a reference for this series). Changes in v3: - added a new patch (patch 2) that isolates the PPC64 exclusive code to calculate the memLockLimit (suggested by Erik Skultety) - fixed 'make syntax-check' errors across all patches - v2 can be found at [2] [1] https://patchwork.kernel.org/cover/10831413/ [2] https://www.redhat.com/archives/libvir-list/2019-March/msg00059.html Daniel Henrique Barboza (4): qemu_domain: simplify non-VFIO memLockLimit calc for PPC64 qemu_domain: add a PPC64 memLockLimit helper qemu_domain: NVLink2 device tree functions for PPC64 PPC64 support for NVIDIA V100 GPU with NVLink2 passthrough src/qemu/qemu_domain.c | 402 ++++++++++++++++++++++++++++++++--------- 1 file changed, 321 insertions(+), 81 deletions(-) -- 2.20.1

[libvirt] [dockerfiles PATCH] Fix name for ppc64le architecture
by Andrea Bolognani 12 Mar '19

12 Mar '19

lcitool expects libvirt architecture names, which means the correct value for little-endian 64-bit PowerPC is ppc64le (VIR_ARCH_PPC64LE). Note that, while "ppc64el" is not an architecture name libvirt would recognize, mips64el (VIR_ARCH_MIPS64EL) and mipsel (VIR_ARCH_MIPSEL) are indeed correct.
