When parsing the top level comment of a file, apibuild.py used
to split on any ':' character of a line regarding the first part
as a key for a setting, e.g. "Summary". The second part would then
be assigned as the value for that key.
This means you could not use a ':' character inside those comments
without ill effects.
Now, a key must consist solely of alphanumeric characters, '_' or '.'.
Problem introduced in commit cd699ed.
* m4/virt-lib.m4 (LIBVIRT_CHECK_LIB, LIBVIRT_CHECK_PKG): Set up
direct expansions, since autoconf 2.59 lacked m4_expand.
I've noticed a number of people sending patches with file
renames not compressed, so we might as well document how to
set this up. (Git won't do it by default, for back-compat
reasons)
* docs/hacking.html.in: Add git config tip.
* HACKING: Regenerate.
If addition of rules in networkAddIptablesRules() failed the real error
was masked by error reported when trying to clean up the remaining
rules.
With this patch the original error message is saved and set back after
the removal is complete.
This patch changes whitespace and the length of the separation line from
this format:
$ virsh net-list --all
Name State Autostart Persistent
--------------------------------------------------
default inactive yes yes
to
$ virsh net-list --all
Name State Autostart Persistent
----------------------------------------------------------
default inactive yes yes
to match the output of virsh list.
Commit 0211fd6e04 introduced regression
where newly defined networks were not made persistent.
This patch makes the network persistent on each successful definition.
Most checks for libraries take the same format
* --with-libFOO=yes|no|check|/some/path argument
* check for a function NNN in libFOO.so
* check for a header file DDD/HHH.h
* Define a WITH_FOO config.h symbol
* Define a WITH_FOO make conditional
* Substitute FOO_CFLAGS and FOO_LIBS make variables
* Print CFLAGS & LIBS summary at the end
Doing all this correctly is rather difficult, typically
done by copy+paste of a previous usage. Further small
improvements people make are not applied to all previous
usages.
Improve this by creating some helper macros to apply
good practice. First, to perform the actual checks:
LIBVIRT_CHECK_LIB([SELINUX], [selinux],
[getfilecon], [selinux/selinux.h])
This checks for 'getfilecon' in -lselinux, and the
existence of 'selinux/selinux.h' header file. If successful
it sets SELINUX_CFLAGS and SELINUX_LIBS. The WITH_SELINUX
config.h macro and WITH_SELINUX make conditional are also
defined.
In some cases we need to check two variants of the same
library
LIBVIRT_CHECK_LIB_ALT([SASL], [sasl2],
[sasl_client_init], [sasl/sasl.h],
[SASL1], [sasl],
[sasl_client_init], [sasl/sasl.h])
This checks for sasl_client_init in libsasl2, and if that
is not found, checks sasl_client_init in libsasl. If the
first check succeeds WITH_SASL is set, while if the second
check succeeds *both* WITH_SASL and WITH_SASL1 are set.
If the library supports pkg-config, then another variant
is available
LIBVIRT_CHECK_PKG([AVAHI], [avahi-client], [0.6.0])
This checks for avahi-client >= 0.6.0 via pkg-config
and sets WITH_AVAHI if found.
Finally to print a summary of CFLAGS & LIBs found (if any):
LIBVIRT_RESULT_LIB([SELINUX])

On rhel5, libs of avahi are packaged into avahi instead of avahi-libs.
Actually, there is no avahi-libs package shipped with rhel5. This patch
fixes this by requiring avahi on rhel5.
The phypUUIDTable_Push and phypUUIDTable_Pull leaked their file descriptors
on normal return. Each function had an unnecessary use of creating a buffer
to print conn->uri->user and needed a bit better flow control. I also noted
that the Read function had a cut-n-paste error from the write function on a
couple of VIR_WARN's.
The openSSHSession leaked the sock on the failure path. Additionally that
turns into the internal_socket in the phypOpen code. That was neither saved
nor closed on any path. So I used the connnection_data->sock field to save
the socket for eventual close. Of interest here is that phypExec used the
connection_data->sock field even though it had never been initialized.
I ran 'make dist' in the directory left over from ./autobuild.sh
(which was configured for a mingw cross build); the resulting
tarball had more files than 'make dist' on a normal Linux build.
I traced it to the fact that we were distributing a generated
file, but only when configure said the end user had to generate
the file in the first place. In the process, I noticed that
we had some difference in symbol file names; I added a comment
explaining why the difference exists (after first trying to
normalize the names and hitting VPATH build failures).
* configure.ac (LIBVIRT_QEMU_SYMBOL_FILE): Add some comments.
* src/Makefile.am (EXTRA_DIST): No need to ship a generated file;
particularly since which file is built depends on configure results.
The daemon-driver-{qemu,lxc} packages are only built if
%{with_driver_modules} is specified, so they do not need to
further test this condition. Likewise, the daemon package
is only built if %{with_libvirtd} is specified, so it does
not need to further test this condition.
* libvirt.spec.in (daemon-driver-qemu, daemon-driver-lxc):
Unconditionally require libvirt-daemon-driver-network.
(daemon): Unconditionally include lock-driver files.
There's no need to do lots of readlink() calls to canonicalize
a name if we're only going to use stat() on it, since stat()
already chases symlinks.
* src/util/virutil.c (virGetDeviceID): Let stat() do the symlink
chasing.
Pass stub driver name directly to pciDettachDevice and pciReAttachDevice to fit
for different libvirt drivers. For example, qemu driver prefers pci-stub, but
Xen prefers pciback.

Add an optional 'type' attribute to <target> element of serial port
device. There are two choices for its value, 'isa-serial' and
'usb-serial'. For backward compatibility, when attribute 'type' is
missing the 'isa-serial' will be chosen as before.
Libvirt XML sample
<serial type='pty'>
<target type='usb-serial' port='0'/>
<address type='usb' bus='0' port='1'/>
</serial>
qemu commandline:
qemu ${other_vm_args} \
-chardev pty,id=charserial0 \
-device usb-serial,chardev=charserial0,id=serial0,bus=usb.0,port=1
With the most recent patch from Claudio, I realized how many
indentation flaws we have in the libvirt.h.in file. Even though
they are harmless, it's still worth fixing them.

With current code, if user calls virDomainPMSuspendForDuration()
followed by virDomainDestroy(), the former API checks for qemu agent
presence, which will evaluate as true (if agent is configured). While
talking to qemu agent, the qemu driver is unlocked, so the latter API
starts executing. However, if machine dies meanwhile, libvirtd gets
EOF on the agent socket and qemuProcessHandleAgentEOF() is called. The
handler clears reference to qemu agent while the destroy API already
holding a reference to it. This leads to NULL dereferencing later in
the code. Therefore, the agent pointer should be set to NULL only if
we are the exclusive owner of it.
When building libvirt rpms on rhel5, I got the following error:
File must begin with "/": rm
File must begin with "/": -f
File must begin with "/": $RPM_BUILD_ROOT/etc/sysctl.d/libvirtd
Installed (but unpackaged) file(s) found:
/etc/sysctl.d/libvirtd
It is triggerd by the %files list of libvirt daemon:
%if 0%{?fedora} >= 14 || 0%{?rhel} >= 6
%config(noreplace) %{_prefix}/lib/sysctl.d/libvirtd.conf
%else
rm -f $RPM_BUILD_ROOT%{_prefix}/lib/sysctl.d/libvirtd.conf
%endif
After checking document of rpm spec file, I think it would be better
to move the file deleting line from %files list to %install script.
Bug introduced in commit a1fd56c.
While OOM can have knock-on effects that trash a system, generally
the first symptom is one of memory thrashing.
* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Reword slightly.
I did a build --without-libvirtd, then ran 'make dist'. The
resulting tarball was broken, with a complaint that make did not
know how to create libvirtd.service.in. I traced it to a use
of EXTRA_DIST inside a conditional.
* daemon/Makefile.am (EXTRA_DIST): Hoist libvirtd.service.in
outside of WITH_LIBVIRTD conditional.
when we has no host's src mapped to container.
there is no .oldroot dir,so libvirt lxc will fail
to start when mouting meminfo.
in this case,the parameter srcprefix of function
lxcContainerMountProcFuse should be NULL.and make
this method handle NULL correctly.

Perform all the appropriate plumbing.
When qemu/KVM VMs are paused manually through a monitor not-owned by libvirt,
libvirt will think of them as "paused" event after they are resumed and
effectively running. With this patch the discrepancy goes away.
This is meant to address bug 892791.

Libvirt's HTML documentation is not as easy to the eyes as it could
be since long text has no visual breaks.
Take advantage of the formatting in documentation comments and wrap
each part separated by two consecutive \n into a HTML <p> element.
Coverity determined that 'emulator' could no longer be set and determined the
code was dead. Looking through the history, I discovered commit-id ed769e18
removed code originally added by commit-id 9237e955 and further modified by
commit-id 6a7e7c4f.
