[libvirt] [PATCH] spec: Enable the iscsi-direct storage driver conditionally
by Andrea Bolognani 14 Aug '18

14 Aug '18

Most distributions we build RPMs on don't ship a recent enough version of libiscsi, so we can't enable the driver unconditionally. Add an explicit dependency on the runtime package while at it.

[libvirt] [PATCH v3 00/11] use GNU C's cleanup attribute in src/util (batch III)
by Sukrit Bhatnagar 14 Aug '18

This third series of patches also modifies a few files in src/util to use VIR_AUTOFREE and VIR_AUTOPTR for automatic freeing of memory and get rid of some VIR_FREE macro invocations and *Free function calls.

[libvirt] [PATCH] bhyve: fix process reconnect
by Roman Bogorodskiy 14 Aug '18

14 Aug '18

To reconnect to the bhyve process after deamon restart, a process VM's pid points to is checked to have proctitle equal to 'bhyve: $vmname'. However, there could be a bug in bhyve(8) which prevents it from setting proctitle, so process arguments will look like: ['/usr/sbin/bhyve', ..., 'vmname', NULL] Fall back to checking this format if proctitle doesn't match as a workaround for this bug. --- src/bhyve/bhyve_process.c | 26 ++++++++++++++++++-------- 1 file changed, 18 insertions(+), 8 deletions(-) diff --git a/src/bhyve/bhyve_process.c b/src/bhyve/bhyve_process.c index 9276d7d364..78d6ff1389 100644 --- a/src/bhyve/bhyve_process.c +++ b/src/bhyve/bhyve_process.c @@ -416,18 +416,28 @@ virBhyveProcessReconnect(virDomainObjPtr vm, if (proc_argv && proc_argv[0]) { if (STREQ(expected_proctitle, proc_argv[0])) { ret = 0; - priv->mon = bhyveMonitorOpen(vm, data->driver); - if (vm->def->ngraphics == 1 && - vm->def->graphics[0]->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC) { - int vnc_port = vm->def->graphics[0]->data.vnc.port; - if (virPortAllocatorSetUsed(vnc_port) < 0) { - VIR_WARN("Failed to mark VNC port '%d' as used by '%s'", - vnc_port, vm->def->name); - } + } else { + if (STREQ(BHYVE, proc_argv[0])) { + int i = 0; + for (; proc_argv[i+1]; i++); + if ((i != 0) && (STREQ(vm->def->name, proc_argv[i]))) + ret = 0; } } } + if (ret == 0) { + priv->mon = bhyveMonitorOpen(vm, data->driver); + if (vm->def->ngraphics == 1 && + vm->def->graphics[0]->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC) { + int vnc_port = vm->def->graphics[0]->data.vnc.port; + if (virPortAllocatorSetUsed(vnc_port) < 0) { + VIR_WARN("Failed to mark VNC port '%d' as used by '%s'", + vnc_port, vm->def->name); + } + } + } + cleanup: if (ret < 0) { /* If VM is reported to be in active state, but we cannot find -- 2.18.0

[libvirt] [PATCH 0/4] Extend apparmor rules for libvirt 4.6
by Christian Ehrhardt 14 Aug '18

14 Aug '18

Hi, this is a summary of things I had to touch recently when working on 4.6. The first two patches are re-submissions and modifications of last year which were never totally challenged, but also not pushed yet (I had no permissions yet back then). The first was lost in a discussion about virt-aa-helper, whicih eventually turned out to be clear that it could not help in that case. - https://www.redhat.com/archives/libvir-list/2017-February/msg01598.html - https://www.redhat.com/archives/libvir-list/2017-March/msg00052.html The second even got a few Acks, but neither made it into upstream yet. Parts of it where introduced already, in 7edcbd02 apparmor: allow libvirt to send term signal to unconfined b482925c apparmor: support ptrace checks But there are still signals blocked with those rules, so I resubmit the remaining bit. Also I added the Acks to the resubmission. The third change came in recently via various bug reports which I finally wanted to adress - e.g. for ceph lib or smb. If we later on spot more cases that have predictable safe paths under /tmp we can add those. Finally the forth change was triggered by me testing libvirt 4.6 in various conditions. Some of them were in containers, and the new libvirt behavior to carry more mount points into the qemu namespace triggers the need to rewrite the existing mount-moving rules that we added last year.

[libvirt] [PATCH v2 RESEND 00/17] Introduce RDT memory bandwidth allocation support
by bing.niu＠intel.com 14 Aug '18

14 Aug '18

From: Bing Niu <bing.niu(a)intel.com> This series is to introduce RDT memory bandwidth allocation support by extending current virresctrl implementation. The Memory Bandwidth Allocation (MBA) feature provides indirect and approximate control over memory bandwidth available per-core. This feature provides a method to control applications which may be over-utilizing bandwidth relative to their priority in environments such as the data-center. The details can be found in Intel's SDM 17.19.7. Kernel supports MBA through resctrl file system same as CAT. Each resctrl group have a MB parameter to control how much memory bandwidth it can utilize in unit of percentage. In this series, MBA is enabled by enhancing existing virresctrl implementation. The policy employed for MBA is similar with CAT: The sum of each MBA group's bandwidth dose not exceed 100%. The enhancement of virresctrl include two main parts: Part 1: Add two new structures virResctrlInfoMemMB and virResctrlAllocMemBW for collecting host system MBA capability and domain memory bandwidth allocation. Those two structures are the extension of existing virResctrlInfo and virResctrlAlloc. With them, virresctrl framework can support MBA and CAT concurrently. Each virResctrlAlloc represent a resource allocation including CAT, or MBA, or CAT&MBA. The policy of MBA is that: total memory bandwidth of each resctrl group, created by virresctrl, does not exceed to 100%. Part 2: On XML part, add new elements to host capabilities query and domain allocation to support memory bandwidth allocation. --------------------------------------------------------------------------------------------- For host capabilities XML, new XML format like below example, <host> ..... <memory_bandwidth> <node id='0' cpus='0-19'> <control granularity='10' min ='10' maxAllocs='8'/> </node> </memory_bandwidth> </host> granularity --- memory bandwidth granularity min --- minimum memory bandwidth allowed maxAllocs --- maximum concurrent memory bandwidth allocation allowed. --------------------------------------------------------------------------------------------- For domain XML, new format as below example <domain type='kvm' id='2'> ...... <cputune> ...... <shares>1024</shares> <memorytune vcpus='0-1'> <node id='0' bandwidth='20'/> </memorytune> </cputune> ...... </domain> id --- node where memory bandwidth allocation will happen bandwidth --- bandwidth allocated in percentage ---------------------------------------------------------------------------------------------- With this extension of the virresctrl, the overall working follow of CAT and MBA is described by below picture. XML parser will aggregate MBA and CAT configuration and represents it in one virresctrl object. The methods of virresctrl class will manipulate resctrl interface to allocate corresponding resources. <memorytune cpus='0-3'> +---------+ | <cachetune vcpus='0-3'> XML | + parser +-----------+ | | +------------------------------+ | | internal object +------v--------------+ virResctrlAlloc | backing object | +------+--------------+ | | +------------------------------+ | +--v-------+ | | | schemata | /sys/fs/resctrl | tasks | | . | | . | | | +----------+ --------------------------------------------------------------------- previous versions and discussion can be found at v1: https://www.redhat.com/archives/libvir-list/2018-July/msg01144.html RFC v2: https://www.redhat.com/archives/libvir-list/2018-June/msg01268.html RFC v1: https://www.redhat.com/archives/libvir-list/2018-May/msg02101.html Changelog: v1 -> this: John's comment: 1.

Complete doc description. eg: update cachetune part about vcpus overlapping with memorytune, update libvirt version info for memory bandwidth control availability. 6. Some coding style fix. RFC_v2->v1: John's comment: 1. use name MemBW to replace MB for a more clear description. 2. split rename patch and put refactor function part separately. 3. split virResctrlInfoMemMB and virResctrlAllocMemBW to different patches. 4. add docs/schemas/*.rng for XML related patches. 5. some cleanup for coding conventions. RFC_ v1->RFC_v2: Jano's comment: 1. put renaming parts into separated patches. 2. set the initial return value as -1. 3. using full name in structure definition. 4. do not use VIR_CACHE_TYPE_LAST for memory bandwidth allocation formatting. Pavel's comment: 1. add host capabilities XML for memory bandwidth allocation. 2. do not mix use cachetune section in XML for memory bandwidth allocation in domain XML. define a dedicated one for memory bandwidth allocation.
