[libvirt] [PATCH] storage: Fix build due to recent storage backend code movement
by John Ferlan 26 Jan '17

26 Jan '17

Commit id '5f07c3c07' broke the freebsd build in the libvirt CI test environment because the UMOUNT was not defined unless WITH_STORAGE_FS is defined. So remove the virStorageBackendUmountLocal from storage_util.c,h and restore the code back in the storage_backend_fs.c and _vstorage.c modules.

[libvirt] [PATCH 0/3] Move FS Storage Backend API's to storage_util
by John Ferlan 26 Jan '17

26 Jan '17

While reviewing the Virtuozzo backend changes it became apparent that my initial review comments weren't fully understood. Rather than going back and forth more on this, I figured I'd take the plunge and make the "preparations". Also since the storage_util is the new dumping ground, I went there. It also already has the API's for the storage backend upload, download, and wipe - so these patches add a few more from the pool class and the rest of the volume class. FWIW: Rather than just making and bundling the changes with the Virtuozzo changes, I figured I'd post them separately just in case someone has agita over the API/helper name changes.

[libvirt] non-standard types in remote XDR definitions
by Matt Broadstone 25 Jan '17

25 Jan '17

Hello, I have been experimenting with the remote protocol defined in the `src/remote/remote_protocol.x` (https://libvirt.org/git/?p=libvirt.git;a=blob_plain;f=src/remote/remote_pro…) and noticed that there a number of types used that are not defined in the XDR RFC, specifically: unsigned char, char, unsigned short, short (I might have missed one or two). I'm wondering if these are missing typedefs, or whether they are custom extensions to the RFC. Does anyone have more information on this? If the latter case is the fact, are these values padded to 4 bytes per the spec? Thanks, Matt

[libvirt] [PATCH] perf: introduce option --reset
by Nitesh Konkar 25 Jan '17

25 Jan '17

Currently you can either enable or disable a perf event. This patch allows you to reset the perf event using command line option --reset. Eg: virsh perf domainName --reset cpu_cycles Signed-off-by: Nitesh Konkar <nitkon12(a)linux.vnet.ibm.com> --- Example: virsh domstats Fedora --perf Domain: 'Fedora' virsh perf Fedora --enable cpu_cycles,cache_references cpu_cycles : enabled cache_references: enabled virsh domstats Fedora --perf Domain: 'Fedora' perf.cpu_cycles=107559185 perf.cache_references=563288 virsh perf Fedora --reset cache_misses,cpu_cycles,cache_references cache_misses : reset cpu_cycles : reset cache_references: reset virsh domstats Fedora --perf Domain: 'Fedora' perf.cpu_cycles=0 perf.cache_references=0 perf.cache_misses=0 virsh perf Fedora --reset cache_misses,cpu_cycles,cache_references --config error: Options --reset and --config are mutually exclusive Should reset option be made available in the domainxml along with enabled=yes/no ? I have not included any such change in this patch as I think that there is no need to reset a perf counter as its value for the VM's pid shall start by default at zero unless enabled. include/libvirt/libvirt-domain.h | 6 +++++ src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 52 ++++++++++++++++++++-------------------- src/qemu/qemu_process.c | 22 +++++++++++++---- src/util/virperf.c | 52 ++++++++++++++++++++++++++++------------ src/util/virperf.h | 12 ++++++---- tools/virsh-domain.c | 37 ++++++++++++++++++---------- 7 files changed, 120 insertions(+), 62 deletions(-) diff --git a/include/libvirt/libvirt-domain.h b/include/libvirt/libvirt-domain.h index e303140..6072f00 100644 --- a/include/libvirt/libvirt-domain.h +++ b/include/libvirt/libvirt-domain.h @@ -2188,6 +2188,12 @@ void virDomainStatsRecordListFree(virDomainStatsRecordPtr *stats);

[libvirt] [PATCH 0/2] *** Expose host's cache information in capabilities ***
by Eli Qiao 25 Jan '17

25 Jan '17

This series patches are the first step to support CAT featues, which also called cache tune in libvirt. First to expose cache information which could be tuned in capabilites XML, later will add some more interface to do cache tune. Some discussion about this feature support can be found from: https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html Eli Qiao (2): Resctrl: Add some utils functions Resctrl: expose cache information to capabilities include/libvirt/virterror.h | 1 + src/Makefile.am | 1 + src/conf/capabilities.c | 30 +++ src/conf/capabilities.h | 15 ++ src/libvirt_private.syms | 5 + src/qemu/qemu_capabilities.c | 42 ++++ src/qemu/qemu_driver.c | 4 + src/util/virerror.c | 1 + src/util/virresctrl.c | 500 +++++++++++++++++++++++++++++++++++++++++++ src/util/virresctrl.h | 121 +++++++++++ tests/Makefile.am | 4 + 11 files changed, 724 insertions(+) create mode 100644 src/util/virresctrl.c create mode 100644 src/util/virresctrl.h -- 1.9.1

[libvirt] [PATCH v2] network: make openvswitch call timeout compile time configurable
by Boris Fiuczynski 25 Jan '17

25 Jan '17

Since a successful completion of the calls to openvswitch is expected a long timeout should be chosen to account for heavily loaded systems. Therefore this patch increases the timeout value from 5 to 120 seconds as default value and also allows to set the openvswitch timeout value by specifying with-ovs-timeout when running configure.
