[libvirt] [PATCH v2 0/3] Honor blacklist for modprobe command
by John Ferlan 30 Jan '14

30 Jan '14

Original patch here: http://www.redhat.com/archives/libvir-list/2014-January/msg01408.html Changes since v1: * Add virkmod.{c,h} to perform the various modprobe commands virModprobeConfig() -> modprobe -c virModprobeLoad() -> modprobe driver virModprobeUnload() -> modprobe -r driver virModprobeUseBlacklist() -> modprobe -b driver * virkmodtest.c to test the functions Caveat emptor... The config is the only test run by default. Loading and Unloading modules is something to be done carefully. * virpci.c Use the virModprobe*() API's instead of a direct MODPROBE * .gitignore Added the /tests/virkmodtest and /examples/domain-events/ which seems to have appeared recently. I can separate them out if desired. NOTE: Since I have no messages in virkmod.c, modifying po/POTFILES.in was deemed unnecessary by a 'make check-syntax' John Ferlan (3): utils: Introduce functions for modprobe tests: Add test for new virkmod functions Honor blacklist for modprobe command .gitignore | 2 + src/Makefile.am | 1 + src/libvirt_private.syms | 7 ++ src/util/virkmod.c | 138 ++++++++++++++++++++++++++++++++ src/util/virkmod.h | 35 +++++++++ src/util/virpci.c | 49 +++++++++--- tests/Makefile.am | 5 ++ tests/virkmodtest.c | 201 +++++++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 429 insertions(+), 9 deletions(-) create mode 100644 src/util/virkmod.c create mode 100644 src/util/virkmod.h create mode 100644 tests/virkmodtest.c -- 1.8.4.2

[libvirt] [libvirt-designer][PATCH] virtxml: Rename to virt-designer
by Michal Privoznik 30 Jan '14

30 Jan '14

Our example utility is called virtxml. However with Cole's latest work, where he introduced virt-xml binary for editing libvirt XML on CLI [1]. It would be better if our example is called virt-designer so we don't confuse users. 1: https://www.redhat.com/archives/libvir-list/2014-January/msg01226.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- .gitignore | 2 +- cfg.mk | 2 +- configure.ac | 2 +- examples/Makefile.am | 10 +++++----- examples/{virtxml.c => virt-designer.c} | 32 ++++++++++++++++---------------- libvirt-designer.spec.in | 4 ++-- 6 files changed, 26 insertions(+), 26 deletions(-) rename examples/{virtxml.c => virt-designer.c} (96%) diff --git a/.gitignore b/.gitignore index 6b05db9..09e15a5 100644 --- a/.gitignore +++ b/.gitignore @@ -15,7 +15,7 @@ Makefile.in /config.log /config.status /configure -/examples/virtxml +/examples/virt-designer /libtool /libvirt-designer-1.0.pc /libvirt-designer.spec diff --git a/cfg.mk b/cfg.mk index 1e4b31d..f9ab008 100644 --- a/cfg.mk +++ b/cfg.mk @@ -104,7 +104,7 @@ sc_copyright_format: prev_version_file = /dev/null -exclude_file_name_regexp--sc_bindtextdomain = ^libvirt-designer/(test|libvirt-designer-main\.c)|^examples/virtxml\.c$$ +exclude_file_name_regexp--sc_bindtextdomain = ^libvirt-designer/(test|libvirt-designer-main\.c)|^examples/virt-designer\.c$$ exclude_file_name_regexp--sc_preprocessor_indentation = ^*/*.[ch]$$ diff --git a/configure.ac b/configure.ac index bad199b..595fea4 100644 --- a/configure.ac +++ b/configure.ac @@ -96,7 +96,7 @@ LIBVIRT_DESIGNER_COVERAGE LIBVIRT_DESIGNER_INTROSPECTION AC_ARG_ENABLE([examples], - AS_HELP_STRING([--enable-examples], [enable virtxml example.

[libvirt] [libvirt-glib 0/3] Add unit tests
by Christophe Fergeau 29 Jan '14

29 Jan '14

This patch series adds support for GTester tests to libvirt-glib, and starts implementing some unit tests for libvirt-gconfig, and for a very specific part of the event handling code. This series https://www.redhat.com/archives/libvir-list/2014-January/msg00939.html is needed for the gconfig test to build and successfully pass. This series https://www.redhat.com/archives/libvir-list/2014-January/msg01359.html is needed too if you don't want the event test to fail. Christophe

[libvirt] ANNOUNCE: virt-xml: Edit libvirt XML with command line options
by Cole Robinson 29 Jan '14

29 Jan '14

I've just pushed a new tool to virt-manager.git called virt-xml. virt-xml uses virt-install's command line options to allow building and editing domain XML. Best way to describe what it can do is with a bunch of examples: See a list of all suboptions that --disk and --network take # virt-xml --disk=? --network=? Change the <description> of domain 'example': # virt-xml example --edit --metadata description="my new description" # Enable the boot device menu for domain 'example': # virt-xml example --edit --boot bootmenu=on Clear the previous <cpu> definition of domain 'winxp', change it to 'host-model', but interactively confirm the diff before saving: # virt-xml winxp --edit --cpu host-model,clearxml=yes --confirm Change the sound cards with model=ac97 to model=ich6 on 'fedora19', but only output the diff: # virt-xml fedora19 --edit model=ac97 --soundhw model=ich6 --print-diff Update the first graphics password to 'foo' of the running VM 'rhel6': # virt-xml rhel6 --edit --graphics password=foo --update Remove the disk path from disk device hdc: # virt-xml rhel6 --edit target=hdc --disk path= Change all disk devices of type 'disk' to use cache=none, using XML from stdin, printing the new XML to stdout. # cat <xmlfile> | virt-xml --edit device=disk --disk cache=none Change all host devices to use driver_name=vfio for VM 'fedora20' on the remote connection # virt-xml --connect qemu+ssh://remotehost/system \ fedora20 --edit all --host-device driver_name=vfio Hotplug host USB device 001.003 to running domain 'fedora19': # virt-xml f19 --add-device --host-device 001.003 --update Add a spicevmc channel to the domain 'winxp', that will be available after the next VM shutdown. # virt-xml winxp --add-device --channel spicevmc Create a 10G qcow2 disk image and attach it to 'fedora18' for the next VM startup: # virt-xml fedora18 --add-device \ --disk /var/lib/libvirt/images/newimage.qcow2,format=qcow2,size=10 Remove the disk vdb from the running domain 'rhel7': # virt-xml rhel7 --remove-device --disk target=vdb Remove all graphics devices from the VM 'rhel7' after the next shutdown: # virt-xml rhel7 --remove-device --graphics all Generate XML for a virtio console device and print it to stdout: # virt-xml --build-xml --console pty,target_type=virtio The man page and --help output have more info, man page at: https://git.fedorahosted.org/cgit/virt-manager.git/tree/man/virt-xml.pod If you are interested in trying it out before it hits any distro, it's really simple: git clone git://git.fedorahosted.org/virt-manager.git cd virt-manager ./virt-xml --help Nothing is set in stone yet, so if anyone has suggestions about the command line syntax or any of the above, please speak up: I plan on cutting a new virt-manager release with virt-xml within the next few weeks. Thanks, Cole
