[libvirt] [sandbox PATCH 00/10] Patches for libvirt-sandbox
by Eren Yagdiran 24 Jun '15

24 Jun '15

Hello, These patches provide disk support for libvirt-sandbox. Implemented '--disk' parameter will be useful when integrating Docker image support for libvirt-sandbox. --Main diffs compared to previous patches. Since many hypervisors, including kvm, will not even honour requested names for disk devices we link each device under /dev/disk/by-tag e.g /dev/disk/by-tag/foobar -> /dev/sda We populate disks.cfg with tag to device mapping when we build the sandbox. After that, in each init-process {Common,Qemu}, we basically read the configuration and populate the right symlinks under /dev/disk/by-tag The common functions for modifying directories are moved under Init-util. {Common,Qemu} inits are using them. Cédric Bosdonnat (2): Add gvir_sandbox_config_has_disks function qemu: use devtmpfs rather than tmpfs to auto-populate /dev Eren Yagdiran (8): Add an utility function for guessing filetype from file extension Add configuration object for disk support Add disk parameter to virt-sandbox Add disk support to the container builder Add disk support to machine builder Init-util : Common directory functions for init-common and init-qemu Common-init: Building symlink from disks.cfg Common-builder: /dev/disk/by-tag/thetag to /dev/vdN bin/virt-sandbox.c | 37 +++ libvirt-sandbox/Makefile.am | 7 +- .../libvirt-sandbox-builder-container.c | 36 ++- libvirt-sandbox/libvirt-sandbox-builder-machine.c | 44 ++- libvirt-sandbox/libvirt-sandbox-builder.c | 73 ++++- libvirt-sandbox/libvirt-sandbox-config-disk.c | 274 +++++++++++++++++++ libvirt-sandbox/libvirt-sandbox-config-disk.h | 82 ++++++ libvirt-sandbox/libvirt-sandbox-config.c | 300 +++++++++++++++++++++ libvirt-sandbox/libvirt-sandbox-config.h | 11 + libvirt-sandbox/libvirt-sandbox-init-common.c | 51 +++- libvirt-sandbox/libvirt-sandbox-init-qemu.c | 151 ++--------- libvirt-sandbox/libvirt-sandbox-init-util.c | 58 ++++ libvirt-sandbox/libvirt-sandbox-init-util.h | 41 +++ libvirt-sandbox/libvirt-sandbox-util.c | 72 +++++ libvirt-sandbox/libvirt-sandbox-util.h | 5 + libvirt-sandbox/libvirt-sandbox.h | 1 + libvirt-sandbox/libvirt-sandbox.sym | 5 + libvirt-sandbox/tests/test-config.c | 11 + po/POTFILES.in | 1 + 19 files changed, 1111 insertions(+), 149 deletions(-) create mode 100644 libvirt-sandbox/libvirt-sandbox-config-disk.c create mode 100644 libvirt-sandbox/libvirt-sandbox-config-disk.h create mode 100644 libvirt-sandbox/libvirt-sandbox-init-util.c create mode 100644 libvirt-sandbox/libvirt-sandbox-init-util.h create mode 100644 libvirt-sandbox/libvirt-sandbox-util.c -- 2.1.0

[libvirt] [PATCH] scsi: Force error for SCSI pools on virStorageBackendSCSIFindLUs failure
by John Ferlan 24 Jun '15

24 Jun '15

Related to : https://bugzilla.redhat.com/show_bug.cgi?id=1171933 Rather than ignore the return status from virStorageBackendSCSIFindLUs, cause a failure to start the pool if a -1 is returned.

[libvirt] [PATCH] vircapstest: Properly report error for failed tests
by Michal Privoznik 24 Jun '15

24 Jun '15

There are two macros used in the test: CAPSCOMP and CAPS_EXPECT_ERR. Both run a test case and if a failure occurred, they set the @ret variable to a value of -1 to indicate an error. Well, that's what they should do. Due to a typo, they set the variable to a positive one effectively masking any failed test. Then, we have couple of tests failing. Fix them too.

[libvirt] [PATCH v2] qemu: Use heads parameter for QXL driver
by Frediano Ziglio 24 Jun '15

Allows to specify maximum number of head to QXL driver. Signed-off-by: Frediano Ziglio <fziglio(a)redhat.com> The patch to support the "max_outputs" in Qemu is still not merged but I got agreement on the name of the argument.

[libvirt] [PATCH] conf: improve the way we format blkiotune and cputune
by Luyao Huang 24 Jun '15

24 Jun '15

Just refactor existing code to use a child buf instead of check all element before format <blkiotune> and <cputune>. This will avoid the more and more bigger element check during we introduce new elements in <blkiotune> and <cputune> in the future.
