[libvirt] [PATCH] Make use of PERF_COUNT_HW_REF_CPU_CYCLES conditional

by Daniel P. Berrange

The PERF_COUNT_HW_REF_CPU_CYCLES constant is not available on all Linux distros libvirt targets, so its use must be made conditional. Other constant have existed long enough that we can assume they exist, as we don't support very old distros like RHEL-5 any more. Signed-off-by: Daniel P.

[libvirt] [PATCH] network: don't use dhcp-authoritative on static networks

by Martin Wilck

"Static" DHCP networks are those where no dynamic DHCP range is defined, only a list of host entries is used to serve permanent IP addresses. On such networks, we don't want dnsmasq to reply to other requests than those statically defined. But "dhcp-authoritative" will cause dnsmasq to do just that. Therefore we can't use "dhcp-authoritative" for static networks.

[libvirt] [PATH v9 00/12] Support cache tune in libvirt

by Eli Qiao

Addressed comment from v9 -> v8 Marcelo: * New public API to query cache usage Eli: * Fix core dump while multiple tasks are added. Addressed comment from v8 -> v7 Martin: * Patch subject prefix. * Move some of cpu related information to virhostcpu.c. * Fix some memory leak in src/utils/resctrl.c Martin & Marcelo: * Don't remove directories which are not maintained by libvirt. Addressed comment from v7 -> v6 Marcelo: * Fix flock usage while VM initialization. Addressed comment from v6 -> v5 Marcelo: * Support other APPs to operate /sys/fs/resctrl at same time Libvirt will scan /sys/fs/resctrl again before doing cache allocation. patch 10 will address this. Addressed comment from v4 -> v5: Marcelo: * Several typos * Use flock instead of virFileLock Addressed comment from v3 -> v4: Daniel & Marcelo: * Added concurrence support Addressed comment from v2 -> v3: Daniel: * Fixed coding style, passed `make check` and `make syntax-check` * Variables renaming and move from header file to c file. * For locking/mutex support, no progress. There are some discussion from mailing list, but I can not find a better way to add locking support without performance impact. I'll explain the process and please help to advice what shoud we do. VM create: 1) Get the cache left value on each bank of the host. This should be shared amount all VMs. 2) Calculate the schemata on the bank based on all created resctrl domain's schemata 3) Calculate the default schemata by scaning all domain's schemata. 4) Flush default schemata to /sys/fs/resctrl/schemata VM destroy: 1) Remove the resctrl domain of that VM 2) Recalculate default schemata 3) Flush default schemata to /sys/fs/resctrl/schemata The key point is that all VMs shares /sys/fs/resctrl/schemata, and when a VM create a resctrl domain, the schemata of that VM depends on the default schemata and all other exsited schematas. So a global mutex is reqired. Before calculate a schemata or update default schemata, libvirt should gain this global mutex. I will try to think more about how to support this gracefully in next patch set. Marcelo: * Added vcpu support for cachetune, this will allow user to define which vcpu using which cache allocation bank. <cachetune id='0' host_id=0 size='3072' unit='KiB' vcpus='0,1'/> vcpus is a cpumap, the vcpu pids will be added to tasks file * Added cdp compatible, user can specify l3 cache even host enable cdp. See patch 8. On a cdp enabled host, specify l3code/l3data by <cachetune id='0' host_id='0' type='l3' size='3072' unit='KiB'/> This will create a schemata like: L3data:0=0xff00;... L3code:0=0xff00;... * Would you please help to test if the functions work. Martin: * Xml test case, I have no time to work on this yet, would you please show me an example, would like to amend it later. This series patches are for supportting CAT featues, which also called cache tune in libvirt. First to expose cache information which could be tuned in capabilites XML. Then add new domain xml element support to add cacahe bank which will apply on this libvirt domain. This series patches add a util file `resctrl.c/h`, an interface to talk with linux kernel's system fs. There are still one TODO left: 1. Expose a new public interface to set cachetune lively. Some discussion about this feature support can be found from: https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html Eli Qiao (12): Resctrl: Add some utils functions Resctrl: expose cache information to capabilities Resctrl: Add new xml element to support cache tune Resctrl: Add private interfaces to operate cache bank Qemu: Set cache tune while booting a new domain. Resctrl: enable l3code/l3data Resctrl: Make sure l3data/l3code are pairs Resctrl: Compatible mode for cdp enabled Resctrl: concurrence support Resctrl: Scan resctrl before doing cache allocation Resctrl: Add Public API for nodecachestats Resctrl: Add nodecachestats daemon/remote.c | 67 +++ docs/schemas/domaincommon.rng | 46 ++ include/libvirt/libvirt-host.h | 32 ++ include/libvirt/virterror.h | 1 + po/POTFILES.in | 1 + src/Makefile.am | 1 + src/conf/capabilities.c | 56 +++ src/conf/capabilities.h | 23 + src/conf/domain_conf.c | 182 +++++++ src/conf/domain_conf.h | 19 + src/driver-hypervisor.h | 7 + src/libvirt-host.c | 41 ++ src/libvirt_private.syms | 12 + src/libvirt_public.syms | 1 + src/nodeinfo.c | 64 +++ src/nodeinfo.h | 1 + src/qemu/qemu_capabilities.c | 8 + src/qemu/qemu_driver.c | 18 + src/qemu/qemu_process.c | 54 ++ src/remote/remote_driver.c | 52 ++ src/remote/remote_protocol.x | 25 +- src/remote_protocol-structs | 16 + src/util/virerror.c | 1 + src/util/virhostcpu.c | 186 ++++++- src/util/virhostcpu.h | 6 + src/util/virresctrl.c | 1082 ++++++++++++++++++++++++++++++++++++++++ src/util/virresctrl.h | 96 ++++ tools/virsh-host.c | 49 ++ 28 files changed, 2129 insertions(+), 18 deletions(-) create mode 100644 src/util/virresctrl.c create mode 100644 src/util/virresctrl.h -- 1.9.1
