[libvirt] [PATCH] build: fix build without numactl
by Eric Blake 21 Jul '14

Under ./configure --without-numactl but with numactl-devel installed, the build fails with: ../../src/util/virnuma.c: In function 'virNumaNodeIsAvailable': ../../src/util/virnuma.c:407:5: error: implicit declaration of function 'numa_bitmask_isbitset' [-Werror=implicit-function-declaration] return numa_bitmask_isbitset(numa_nodes_ptr, node); ^ and other failures, all because the configure results for particular functions were used without regard to whether libnuma was even being linked in. * src/util/virnuma.c (virNumaGetPages): Fix message typo.

[libvirt] [REPOST 0/8] storage_scsi: Stable SCSI host addressing
by John Ferlan 21 Jul '14

21 Jul '14

Reposting of a series from last month changing only the span version in the docs from 1.2.6 to 1.2.7. Previous posting here: http://www.redhat.com/archives/libvir-list/2014-June/msg00448.html The concept still remains the same - rather than rely on the hostNN numbers for the scsi_host to remain stable and unique across host reboots and/or kernel rebuilds, allow use a combination of the scsi_host's PCI address and the value from the hostNN's 'unique_id' file.

[libvirt] [PATCH] schema: pool: netfs: Don't enforce slash in glusterfs pool source
by Peter Krempa 21 Jul '14

21 Jul '14

Gluster volumes don't start with a leading slash. Our schema for netfs gluster pools enforces it though. Luckily mount.glusterfs skips it.

[libvirt] [PATCH] domtop: Fix build on mingw
by Michal Privoznik 21 Jul '14

21 Jul '14

Firstly, there's no sigaction() nor struct sigaction on mingw. We have to use the one implemented by gnulib (and hence link with gnulib). Then, for some reason one header file from windows defines ERROR symbol. Yes it does. Sigh.
