[libvirt] [PATCH] util: increase libnl buffer size to 1M
by ZhiPeng Lu 16 Jul '17

16 Jul '17

nl_recv() returns the error "No buffer space available" when using virsh destroy domain with 240 or more passhthrough network interfaces. The patch increases libnl sock receive buffer size to 1M, and nl_recv() doesn't return error when destroying domain with 512 network interfaces.

[libvirt] [PATCH 00/17] nwfilter adjustments for common object
by John Ferlan 16 Jul '17

16 Jul '17

As noted in the recently posted virObject changes: https://www.redhat.com/archives/libvir-list/2017-June/msg00070.html I believe I've found a way to handle the recursive lock situation that made it "difficult" (at best) to convert the nwfilter to the common object model. It does involve a bit of a circuitous route to "temporarily implement" the refcnt in nwfilter, but that gets removed rather quickly. Beyond that there's a bit of setup, the first few patches deal with issues seen while working through this code and then more setup for getting things to be more common with other drivers (so when they disappear a bit further into the future) into some new object it'll be obvious where/why they're there. The middle few patches deal with an insane naming scheme for a single function that seemed to keep prefixing "_" as a new function was created. So it's a bit of name change, but makes it easier to think about. The last 4 patches deal with the conversion to use a @ref, a change to a list locking hash table model, the modificiation of the recursive instantiation to use @refs rather than @locks, and finally the change to use the existing lockable object. I have run these through the various avacodo nwfilter tests that I could find, but perhaps if someone that had a more "robust configuration" and wants to be a bit adventurous and also give the patches a whirl - that would be appreciated.

[libvirt] [PATCH 0/8] More virsecretobj changes to prepare for common object
by John Ferlan 14 Jul '17

14 Jul '17

A couple I forgot from earlier series, but a few things found since then along with some clarifications to make the ObjAdd processing a bit more like I've found for nwfilter, nodedev, and interface as well as making the ObjListRemove processing a bit clearer and more consistent. Along with the other series and the virObject v2 adjustments - this brings everything close enough to start sending the patches that will tie all this stuff together to create/use a common object model. John Ferlan (8): secret: Whitespace modification for secret_driver secret: Alter FindByUUID to expect the formatted uuidstr secret: Rename variable in virSecretObjListAdd secret: Clean up virSecretObjListAdd processing secret: Remove need for local configFile and base64File in ObjectAdd secret: Have virSecretObjNew consume newdef secret: Properly handle @def after virSecretObjAdd in driver secret: Handle object list removal and deletion properly src/conf/virsecretobj.c | 125 +++++++++++++++++++++------------------------ src/conf/virsecretobj.h | 2 +- src/secret/secret_driver.c | 50 ++++++++++++------ 3 files changed, 94 insertions(+), 83 deletions(-) -- 2.9.4

[libvirt] [PATCH] cpu_x86: Properly disable unknown CPU features
by Jiri Denemark 13 Jul '17

13 Jul '17

CPU features unknown to a hypervisor will not be present in dataDisabled even though the feature won't naturally be enabled because it is unknown. Thus any features we asked for which are not in dataEnabled should be considered disabled.

[libvirt] [PATCH] qemu: handle missing bind host/service on chardev hotplug
by Ján Tomko 11 Jul '17

On domain startup, bind host or bind service can be omitted and we will format a working command line.

[libvirt] [PATCH 0/9] Properly implement json pseudo-protocol string deflattening
by Peter Krempa 11 Jul '17

11 Jul '17

In qemu's new syntax starting from 2.9 it's possible to have nested objects in the json pseudo protocol string specifying a backing store for an image. Libvirt would not be able to handle some of them, since the json deflattener was meant to deflatten only 1 layer. Peter Krempa (9): tests: Rename jsontest to virjsontest util: json: Add virJSONValueIsObject util: Move JSON object deflattening code to json utility file util: json: Don't remove the 'file' subobject when deflattening tests: json: Add test for the deflattening function util: json: Properly implement JSON deflattening util: json: Recursively deflatten objects virJSONValueObjectDeflatten util: storage: Always deflatten JSON pseudo-protocol objects tests: Validate that JSON deflattening fixed nested json pseudo-protocol strings src/libvirt_private.syms | 2 + src/util/virjson.c | 115 +++++++++++++++++++++ src/util/virjson.h | 4 + src/util/virstoragefile.c | 79 ++------------ tests/Makefile.am | 8 +- tests/virjsondata/deflatten-basic-file-in.json | 8 ++ tests/virjsondata/deflatten-basic-file-out.json | 10 ++ tests/virjsondata/deflatten-basic-generic-in.json | 14 +++ tests/virjsondata/deflatten-basic-generic-out.json | 20 ++++ .../deflatten-concat-double-key-in.json | 7 ++ tests/virjsondata/deflatten-concat-in.json | 5 + tests/virjsondata/deflatten-concat-out.json | 8 ++ tests/virjsondata/deflatten-deep-file-in.json | 9 ++ tests/virjsondata/deflatten-deep-file-out.json | 23 +++++ tests/virjsondata/deflatten-deep-generic-in.json | 9 ++ tests/virjsondata/deflatten-deep-generic-out.json | 27 +++++ tests/virjsondata/deflatten-double-key-in.json | 4 + tests/virjsondata/deflatten-nested-in.json | 16 +++ tests/virjsondata/deflatten-nested-out.json | 28 +++++ tests/virjsondata/deflatten-qemu-sheepdog-in.json | 11 ++ tests/virjsondata/deflatten-qemu-sheepdog-out.json | 13 +++ tests/virjsondata/deflatten-unflattened-in.json | 12 +++ tests/virjsondata/deflatten-unflattened-out.json | 14 +++ tests/{jsontest.c => virjsontest.c} | 75 ++++++++++++++ tests/virstoragetest.c | 10 ++ 25 files changed, 458 insertions(+), 73 deletions(-) create mode 100644 tests/virjsondata/deflatten-basic-file-in.json create mode 100644 tests/virjsondata/deflatten-basic-file-out.json create mode 100644 tests/virjsondata/deflatten-basic-generic-in.json create mode 100644 tests/virjsondata/deflatten-basic-generic-out.json create mode 100644 tests/virjsondata/deflatten-concat-double-key-in.json create mode 100644 tests/virjsondata/deflatten-concat-in.json create mode 100644 tests/virjsondata/deflatten-concat-out.json create mode 100644 tests/virjsondata/deflatten-deep-file-in.json create mode 100644 tests/virjsondata/deflatten-deep-file-out.json create mode 100644 tests/virjsondata/deflatten-deep-generic-in.json create mode 100644 tests/virjsondata/deflatten-deep-generic-out.json create mode 100644 tests/virjsondata/deflatten-double-key-in.json create mode 100644 tests/virjsondata/deflatten-nested-in.json create mode 100644 tests/virjsondata/deflatten-nested-out.json create mode 100644 tests/virjsondata/deflatten-qemu-sheepdog-in.json create mode 100644 tests/virjsondata/deflatten-qemu-sheepdog-out.json create mode 100644 tests/virjsondata/deflatten-unflattened-in.json create mode 100644 tests/virjsondata/deflatten-unflattened-out.json rename tests/{jsontest.c => virjsontest.c} (89%) -- 2.12.2
