Eugene Marcotte reported that if gcrypt-devel (a prereq of
gnutls-devel) is not present, then compilation fails due to
an unconditional use of <gcrypt.h>.
* src/libvirt.c (includes): Properly guard use of gcrypt.h.
This reverts commit 0bbbd42c30.
The design for this feature is not complete, and may change the

This reverts commit 24aa7f8d11.
The implementation to match the documentation is not complete yet,

virstoragetest was failing on RHEL 5, but with no good error message:
TEST: virstoragetest
0 FAIL
It turns out that qemu-img was so old, that it lacked support for
-o backing_file. It didn't help that the test was also using
qemu-img from PATH, even after first probing for kvm-img.
* tests/virstoragetest.c (testPrepImages): Consistently use
discovered binary. Skip instead of fail if qemu-img fails during
setup.
The parallels storage driver declared some loop variables
inside the for(;;). This is not allowed by libvirt coding

qemu: Remove the shared disk entry if the operation is ejecting or updating
It was still accessing disk->src, when the entire 'disk' object
has been free'd already. Even if it weren't free'd, accessing
the 'src' value of virDomainDiskDef is not allowed without
first validating disk->type is file or block. Just remove the
broken code entirely.

On RHEL 5, 'make check' included failures such as:
TEST: virstoragetest
unable to create directory /virstoragedata/sub
unable to return to correct directory, refusing to clean up /virstoragedata
It turns out that with automake 1.9.x, $(abs_builddir) is not
automatically provided. We have previously worked around this
by using `pwd` before, but because we did not do it everywhere,
we had a number of broken tests.
This patch brings RHEL 5 from 8 failed tests down to 5 (the
remaining failures may be due to bugs in the older libxml2 and
RNG schema validation available in RHEL 5, so I'm not sure if
they can be fixed in libvirt, but I'm still investigating).
* tests/Makefile.am (AM_CFLAGS): Reliably set abs_builddir.
(*_la_CFLAGS): Factor out common settings; delete when nothing
remains to be added.
On RHEL 5, I noticed this test failure message:
TEST: qemumonitorjsontest
libvirt not compiled with yajl, skippingSKIP: qemumonitorjsontest
* tests/virstoragetest.c (testPrepImages): Use simpler fputs.
* tests/qemumonitorjsontest.c (mymain): Ensure trailing newline.
VIR_ERR_NO_CONNECT already contains "no connection driver available".
This patch changes:

to:
no connection driver available for hello

Currently we call virSetDeviceUnprivSGIO with val == 0 if a block device
has an sgio attribute. But for sgio='filtered', we know that a
kernel with no unpriv_sgio support will always behave as the user
wanted. In this case, there is no need to call the function and
report a (bogus) error.

testutils.c likes to print summaries after a test completes,
including if it failed. But if the test outright exit()s,
this summary is skipped. Enforce that we return instead of exit.
* cfg.mk (sc_prohibit_exit_in_tests): New syntax check.
* tests/commandhelper.c (main): Fix offenders.
* tests/qemumonitorjsontest.c (mymain): Likewise.

Now that the segfault is solved, we can skip instead of fail
the test when yajl is not present.
* tests/qemumonitorjsontest.c (mymain): Skip if no yajl.
On a machine without yajl headers, I was seeing random segfaults
from qemumonitorjsontest (about 90% of the runs on my particular
machine). The segfault was inside virClassIsDerivedFrom, which
points to a case of a race leading to unreferencing a stale
pointer to an object that had already been freed. I also noticed
that if I got the segfault, I was seeing messages such as:
2013-02-22 16:12:37.504+0000: 19833: error : virNetSocketWriteWire:1361 : Cannot write data: Bad file descriptor
which is also evidence of deferencing a stale pointer. I traced it
to a race where qemuMonitorTestIO could execute late, after the
main thread had already called qemuMonitorTestFree and called
virNetSocketClose(test->client) but not clearing it out to NULL.
Sure enough, after test->client has been closed, fd is -1, which
causes an attempt to write to the socket to fail, which in turn
triggers the error code of qemuMonitorTestIO that tries to re-close
test->client.
* tests/qemumonitortestutils.c (qemuMonitorTestIO): Don't attempt
to free client again if test already quit.
If virCondInit fails (okay, so that's unlikely), then we end up
attempting a virObjectUnlock() on the cleanup path, even though
we don't hold a lock. This is not guaranteed to be safe. While
at it, I noticed a couple places where we were referencing mon->fd
outside locks.
* src/qemu/qemu_monitor.c (qemuMonitorOpenInternal): Minimize lock
duration. mon->watch doesn't need clean up on error.
(qemuMonitorGetBlockExtent, qemuMonitorBlockResize): Don't
dereference fd outside of lock.
I built without yajl support, and noticed a strange failure message
in qemumonitorjsontest:
2013-02-22 16:12:37.503+0000: 19812: error : virJSONValueToString:1119 : internal error No JSON parser implementation is available
2013-02-22 16:12:37.503+0000: 19812: error : qemuMonitorJSONCommandWithFd:253 : out of memory
While a later patch will fix the test to skip when json is not present,
this patch avoids overriding the more useful error message from
virJSONValueToString returning NULL.
* src/qemu/qemu_monitor_json.c (qemuMonitorJSONCommandWithFd):
Don't override message.
(qemuMonitorJSONCheckError): Don't print NULL.
* src/qemu/qemu_agent.c (qemuAgentCommand): Don't override message.
(qemuAgentCheckError): Don't print NULL.
(qemuAgentArbitraryCommand): Properly fail on OOM.
The new TypedParam helper APIs allow to simplify this function
significantly.
This patch integrates the fix in 75e5bec97b
by correctly ordering the setting functions instead of reordering the
parameters.
The bridge device was showing the vnet devices created for the domains
as connected to the bridge. libvirt should only show host devices when
trying to get the interface definition rather than the domain devices as
well.

This patch adds a new capability bit QEMU_CAPS_OBJECT_RNG_EGD and code
to support the egd backend for the VirtIO RNG device.
The device is added by 3 qemu command line options:
-chardev socket,id=charrng0,host=1.2.3.4,port=1234 (communication
backend)
-object rng-egd,chardev=charrng0,id=rng0 (RNG protocol client)
-device virtio-rng-pci,rng=rng0,bus=pci.0,addr=0x4 (the RNG device)
This patch implements support for the virtio-rng-pci device and the
rng-random backend in qemu.
Two capabilities bits are added to track support for those:
QEMU_CAPS_DEVICE_VIRTIO_RNG - for the device support and
QEMU_CAPS_OBJECT_RNG_RANDOM - for the backend support.
qemu is invoked with these additional parameters if the device is
enabled:
-object rng-random,id=rng0,filename=/test/phile (to add the backend)
-device virtio-rng-pci,rng=rng0,bus=pci.0,addr=0x4 (to add the device)
This patch adds basic configuration support for the RNG device
supporting the virtio model with the "random" and "egd" backend types as
described in the schema in the previous patch.
This patch documents XML elements used for (basic) support of virtual
RNG devices.
In the devices section in the domain XML users may specify:
For the default 'random' backend:
<devices>
<rng model='virtio'>
<backend model='random'>/dev/urandom</backend>
</rng>
</devices>
For the slightly more advanced EGD backend:
<devices>
<rng model='virtio'>
<backend model='egd' type='udp'>
<!-- this is a definition of a character device -->
<source mode='bind' service='1234'/>
<source mode='connect' host='1.2.3.4' service='1234'/>
<!-- or other valid character device configuration -->
</backend>
</rng>
</devices>
For the planned random daemon/pool:
<devices>
<rng model='virtio'>
<backend model='pool' pool='poolname'>class</backend>
</rng>
</devices>
to enable the RNG device for guests.
This patch adds a fake switch statement to force the compiler to warn
after a new device type was added. This should remind the contributor to
add the new device also to this iterator function.
Originally, only a host name was used to associate a
DHCPv6 request with a specific IPv6 address. Further testing
demonstrates that this is an unreliable method and, instead,
a client-id or DUID needs to be used. According to DHCPv6
standards, this id can be a duid-LLT, duid-LL, or duid-UUID
even though dnsmasq will accept almost any text string.
Although validity checking of a specified string makes sure it is
hexadecimal notation with bytes separated by colons, there is no
rigorous check to make sure it meets the standard.
Documentation and schemas have been updated.

For really old qemu-img binaries which do not support specifying
the format of the backing file, display a DEBUG message instead of
INFO that this can't be done.
It makes no sense to prohibit reuse of the wrapper in other LGPL
projects, since most of libvirt is designed to be LGPL. Of
course, when using the wrapper to wrap a GPL program, the combined
result is still effectively GPL, but that shouldn't force us to
license the wrapper as GPL in isolation.
* run.in: Relicense to LGPLv2+.
This function does the source part of NBD magic. It
invokes drive-mirror on each non shared and RW disk with
a source and wait till the mirroring process completes.
When it does we can proceed with migration.
Currently, an active waiting is done: every 500ms libvirt
asks qemu if block-job is finished or not. However, once
the job finishes, qemu doesn't report its progress so we
can only assume if the job finished successfully or not.
The better solution would be to listen to the event which
is sent as soon as the job finishes. The event does
contain the result of job.
We need to start NBD server and feed it with all non-<shared/>,
RW and source-full disks. Moreover, with new virPortAllocator we
must ensure the borrowed port for NBD server will be returned if
either migration completes or qemu process is torn down.
This will be used with new migration scheme.
This patch creates basically just monitor stub
functions. Wiring them into something useful
is done in later patches.

This patch creates basically just monitor stub

This migration cookie is meant for two purposes. The first is to be sent
in begin phase from source to destination to let it know we support new
implementation of VIR_MIGRATE_NON_SHARED_{DISK,INC} so destination can
start NBD server. Then, the second purpose is, destination can let us
know, on which port the NBD server is running.
This patch adds support for a new <option>-Tag in the <dhcp> block of
network configs, based on a subset of the fifth proposal by Laine
Stump in the mailing list discussion at
https://www.redhat.com/archives/libvir-list/2012-November/msg01054.html.
Any such defined option will result in a dhcp-option=<number>,"<value>"
statement in the generated dnsmasq configuration file.
Currently, DHCP options can be specified by number only and there is
no whitelisting or blacklisting of option numbers, which should
probably be added.
