[libvirt] [PATCH] qemu_monitor_json: Properly check GetArray return value
by Jiri Denemark 15 Feb '17

15 Feb '17

Commit 2a8d40f4ec refactored qemuMonitorJSONGetCPUx86Data and replaced virJSONValueObjectGet(reply, "return") with virJSONValueObjectGetArray. While the former is guaranteed to always return non-NULL pointer the latter may return NULL if the returned JSON object is not an array.

[libvirt] [PATCH] qemu: Filter ARAT CPU feature from host-model
by Jiri Denemark 14 Feb '17

14 Feb '17

ARAT feature was first introduced in QEMU 2.4.0, which means host-model CPU mode is unusable with QEMU < 2.4.0 on any host CPU which supports ARAT. Let's not include this feature in host-model CPUs unless a user explicitly asks for it. Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- Notes: We will do this properly in the future since we will ask QEMU what CPU features it understands and what it thinks about host CPU. However, the required QMP interface is not upstream yet. src/qemu/qemu_capabilities.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index cfd090c3f..2da4c76ab 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -2959,7 +2959,8 @@ virQEMUCapsCPUFilterFeatures(const char *name, { if (STREQ(name, "cmt") || STREQ(name, "mbm_total") || - STREQ(name, "mbm_local")) + STREQ(name, "mbm_local") || + STREQ(name, "arat")) return false; return true; -- 2.11.0.rc2

[libvirt] [PATCHv2] qemu: Emit domain events for all virtio-serial channels
by Matt Broadstone 14 Feb '17

14 Feb '17

Presently domain events are emitted for the "agent lifecycle" which is a specialization on virtio-serial events specific to the channel named "org.qemu.guest_agent.0". This patch adds a generic event for "channel lifecycles", which emit state change events for all attached channels. --- daemon/remote.c | 42 +++++++++++++++++ examples/object-events/event-test.c | 57 ++++++++++++++++++++++++ include/libvirt/libvirt-domain.h | 44 ++++++++++++++++++ src/conf/domain_event.c | 89 +++++++++++++++++++++++++++++++++++++ src/conf/domain_event.h | 12 +++++ src/libvirt_private.syms | 2 + src/qemu/qemu_driver.c | 5 +++ src/qemu/qemu_process.c | 6 +++ src/remote/remote_driver.c | 32 +++++++++++++ src/remote/remote_protocol.x | 17 ++++++- src/remote_protocol-structs | 7 +++ tools/virsh-domain.c | 35 +++++++++++++++ 12 files changed, 347 insertions(+), 1 deletion(-) diff --git a/daemon/remote.c b/daemon/remote.c index e414f92..25b32f2 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -1086,6 +1086,47 @@ remoteRelayDomainEventAgentLifecycle(virConnectPtr conn, static int +remoteRelayDomainEventChannelLifecycle(virConnectPtr conn, + virDomainPtr dom, + const char *channelName, + int state, + int reason, + void *opaque) +{ + daemonClientEventCallbackPtr callback = opaque;

[libvirt] [PATCH] qemu: Set umask before calling mknod()
by Andrea Bolognani 14 Feb '17

14 Feb '17

When we populate the private /dev that's going to be used by an isolated QEMU process, we take care all metadata matches what's in the top-level namespace: in particular, we copy the file permissions directly. However, since the permissions passed to mknod() are still affected by the active umask, we need to set it to a very permissive value before creating device nodes to avoid file access issues.

[libvirt] [PATCH] RFC: qemu: add spice/virgl rendernode
by marcandre.lureau＠redhat.com 14 Feb '17

14 Feb '17

From: Marc-André Lureau <marcandre.lureau(a)redhat.com> I am working on a WIP series to add QEMU Spice/virgl rendernode option. Since rendernodes are not stable across reboots, I propose that QEMU accepts also a PCI address (other bus types may be added in the future). This is how I translated it to libvirt. I picked <gpu> over <rendernode>, since it seems more generic. Comments welcome!

[libvirt] [RFC v3 0/8] Support cache tune in libvirt
by Eli Qiao 13 Feb '17

13 Feb '17

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 sys fs. There are still some TODOs such as expose new public interface to get free cache information. Some discussion about this feature support can be found from: https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html Eli Qiao (8): Resctrl: Add some utils functions Resctrl: expose cache information to capabilities Resctrl: Add new xml element to support cache tune Resctrl: Add private interface to set cachebanks Qemu: Set cache banks Resctrl: enable l3code/l3data Resctrl: Make sure l3data/l3code are pairs Resctrl: Compatible mode for cdp enabled docs/schemas/domaincommon.rng | 46 ++ 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/libvirt_private.syms | 11 + src/nodeinfo.c | 64 +++ src/nodeinfo.h | 1 + src/qemu/qemu_capabilities.c | 8 + src/qemu/qemu_driver.c | 6 + src/qemu/qemu_process.c | 53 ++ src/util/virerror.c | 1 + src/util/virresctrl.c | 1091 +++++++++++++++++++++++++++++++++++++++++ src/util/virresctrl.h | 85 ++++ 17 files changed, 1649 insertions(+) create mode 100644 src/util/virresctrl.c create mode 100644 src/util/virresctrl.h -- 1.9.1
