The "Default-Stop" field in LSB comment in libvirt-guests is missing and should
be added. I also suggests to add runlevel 2 to the "Default-Start" field.

When libvirt-guests is being stopped, I get the following message:
$Running guests on default URI: test-vm
$Suspending guests on default URI...
$Suspending test-vm: /etc/init.d/libvirt-guests: 340: Syntax error: Bad fd
number
Remove the optional option "group", as cmdHelp should accepts
only one option ("virsh help" supports both command and command
group now, and user rarely uses the options, so it doesn't matter
much for it being longer, :-)
* tools/virsh.c
* tools/virsh.c (find-storage-pool-sources-as and find-storage-pool-sources
should't be in command group "Domain Management", move them to group
"Storage Pool".
* tools/virsh.c (virsh shouldn't use 'phy' as the disk driver if
user doesn't specify "--driver", it causes bugs, as not all of
hypervisor driver supports 'phy', and actually hypervisor should
known the correct default disk driver and subdriver, so remove it)
As virsh help supports both command and command group now,
update "cmdHelp" to print consite help, (this patch is
increment of "7829052757953023b0826e0293ffe18ed4ab89e9").
And also remove redundant empty line in "vshUsage".
* tools/virsh.c
The output was previously:
-c | --connect <uri> hypervisor connection URI
-r | --readonly connect readonly
-d | --debug <num> debug level [0-5]
-h | --help this help
-q | --quiet quiet mode
-t | --timing print timing information
-l | --log <file> output logging to file
-v | --version[=short] program version
-V | --version=long version and full options
(note the blank line between the --version types)
This patch removes the extra blank line.
Change the virsh help out. The new output of "virsh help" and
"virsh --help" will be like:
Secret (help keyword 'secret'):
secret-define define or modify a secret from an XML file
secret-dumpxml secret attributes in XML
secret-set-value set a secret value
secret-get-value Output a secret value
secret-undefine undefine a secret
secret-list list secrets
Snapshot (help keyword 'snapshot'):
snapshot-create Create a snapshot
snapshot-current Get the current snapshot
snapshot-delete Delete a domain snapshot
snapshot-dumpxml Dump XML for a domain snapshot
snapshot-list List snapshots for a domain
snapshot-revert Revert a domain to a snapshot
Also support output help information of specified command group, e.g.
% ./tools/virsh help "Network Filter"
Network Filter (help keyword 'filter'):
nwfilter-define define or update a network filter from an XML file
nwfilter-undefine undefine a network filter
nwfilter-dumpxml network filter information in XML
nwfilter-list list network filters
nwfilter-edit edit XML configuration for a network filter
Each group has a help keyword, e.g.
% ./tools/virsh help filter
Network Filter (help keyword 'filter'):
nwfilter-define define or update a network filter from an XML file
nwfilter-undefine undefine a network filter
nwfilter-dumpxml network filter information in XML
nwfilter-list list network filters
nwfilter-edit edit XML configuration for a network filter
* tools/virsh.c:
- introduce new struct "vshCmdGrp" and macros to define the groups.
- split previous array "commands" into small arrays which are orgnized
by group
- changed some functions, e.g. "vshCmdDefSearch"
- Added new functions, e.g. "vshCmdGrpSearch"
- commands of each group are in "alphabetical order" now.
- command groups are in "alphabetical order" now.
- the commands are categorized with reference of
http://wiki.libvirt.org/page/VirshHelpV2 (by Justin)
- the modifications doesn't affect tests
* TODO:
- doc
Making this change makes it easier to spot the memory leaks
that will be fixed in the next patch.
* cfg.mk (sc_prohibit_xmlGetProp): New rule.
* .x-sc_prohibit_xmlGetProp: New exception.
* Makefile.am (EXTRA_DIST): Ship exception file.
* tools/virsh.c (cmdDetachInterface, cmdDetachDisk): Adjust
offenders.
* src/conf/storage_conf.c (virStoragePoolDefParseSource):
Likewise.
* src/conf/network_conf.c (virNetworkDHCPRangeDefParseXML)
(virNetworkIPParseXML): Likewise.
virsh was not checking for a error code when listing storage
volumes. So when listing volumes in a pool that was shutoff,
no output was displayed
* tools/virsh.c: Fix error handling when listing volumes
The "find-storage-pool-sources-as" command takes two arguments,
a hostname and a port number. For some reason the code would
also then look for a port number appended to the hostname
string by searching for ':'. This totally breaks if the user
gives an IPv6 address, and is redundant, since you can already
provide a port as a separate argument
* tools/virsh.c: Remove bogus port number handling code
The code generating XML for storage pool source discovery is
hardcoded to only allow a hostname and optional port number.
Refactor this code to make it easier to add support for extra
parameters.
* tools/virsh.c: Refactor XML generator
The virt-mem program is no longer shipped, but was still being
referenced at the bottom of the virsh and libvirtd man pages.
This patch removes it from those man pages, addressing
BZ# 639603:
https://bugzilla.redhat.com/show_bug.cgi?id=639603
Last time I ran ./autobuild.sh was on F13; and upgrading to F14
exposed these leftovers due to a newer gcov than what was in the stale
files, in the form of spurious messages that break 'make check':
+profiling:/home/remote/eblake/libvirt-tmp/tools/virsh-console.gcda:Version mismatch - expected 405R got 404R
and concluding with a bug in the autobuild.sh script itself:
./autobuild.sh: line 44: test: =: unary operator expected
* autobuild.sh: avoid syntax error on failed test
* tools/Makefile.am (CLEANFILES): Clean coverage files.
Per the gettext developer:
http://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00019.htmlhttp://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00021.html
gettext() doesn't work correctly on all platforms unless you have
called setlocale(). Furthermore, gnulib's gettext.h has provisions
for setting up a default locale, which is the preferred method for
libraries to use gettext without having to call textdomain() and
override the main program's default domain (virInitialize already
calls bindtextdomain(), but this is insufficient without the
setlocale() added in this patch; and a redundant bindtextdomain()
in this patch doesn't hurt, but serves as a good example for other
packages that need to bind a second translation domain).
This patch is needed to silence a new gnulib 'make syntax-check'
rule in the next patch.
* daemon/libvirtd.c (main): Setup locale and gettext.
* src/lxc/lxc_controller.c (main): Likewise.
* src/security/virt-aa-helper.c (main): Likewise.
* src/storage/parthelper.c (main): Likewise.
* tools/virsh.c (main): Fix exit status.
* src/internal.h (DEFAULT_TEXT_DOMAIN): Define, for gettext.h.
(_): Simplify definition accordingly.
* po/POTFILES.in: Add src/storage/parthelper.c.
I am replacing the last instances of close() I found with VIR_CLOSE() / VIR_FORCE_CLOSE respectively.
The first part patches virsh, which I missed out on previously.
The 2nd patch I had left out intentionally to look at it more carefully:
The 'closed' variable could be easily removed since it wasn't used anywhere else. The possible race condition that could result from the filedescriptor being closed and not set to -1 (and possibly let us write into 'something' totally different if the fd was allocated by another thread) seems to be prevented by the qemuMonitorLock() already placed around the code that reads from or writes to the fd. So the change of this code as shown in the patch should not have any side-effects.
The event watches need to be removed before the event loop
terminates, otherwise they cause a dangling reference to
be held on the virStreamPtr, which in turns holds a reference
on virConnectPtr, which in turn causes errors like
"Failed to disconnect from the hypervisor"
* tools/console.c: Remove watches before event loop quits
* tools/virsh.c: Print out dangling reference count
This re-writes the 'virsh console' command so that it uses
the new streams API. This lets it run remotely and/or as a
non-root user. This requires that virsh be linked against
the simple event loop from libvirtd in daemon/event.c
As an added bonus, it can now connect to any console device,
not just the first one.
* tools/Makefile.am: Link to event.c
* tools/console.c, tools/console.h: Rewrite to use the
virDomainOpenConsole() APIs with streams
* tools/virsh.c: Support choosing the console name
via --devname $NAME
* tools/virsh.c (vshParseArgv): Use NULL instead of 0 for pointer,
and symbolic names for has_arg. Give --version an optional arg.
(vshUsage): Document this.
* tools/virsh.pod: Likewise.
Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
To ease debugging this trivial patch allows to find what was compiled
in in the local version of libvirt, this doesn't work for remote access
but that's probably sufficient. With the patch I get on my machine:
paphio:~/libvirt/tools -> ./virsh -V
Virsh command line tool of libvirt 0.8.4
See web site at http://libvirt.org/
Compiled with support for:
Hypervisors: Xen QEmu/KVM UML OpenVZ LXC ESX PHYP Test
Networking: Remote Daemon Network Bridging Netcf Nwfilter
Storage: Dir Disk Filesystem SCSI Multipath iSCSI LVM
Miscellaneous: SELinux Secrets Debug Readline
paphio:~/libvirt/tools ->
* tools/virsh.c: add -V option
* tools/virsh.pod: document the extension
Now that the virsh parsing has been revamped, we can
implement qemu-monitor-command. This is basically the same
as it was in previous iterations, but has now been tested to
work both with the plain text monitor and the QMP monitor.
