When we set migrate_speed by json, we receive the following
error message:
libvirtError: internal error unable to execute QEMU command
'migrate_set_speed': Invalid parameter type, expected: number
The reason is that: the arguments of migrate_set_speed
by json is json number, not json string.

The nodeinfo structure includes
nodes : the number of NUMA cell, 1 for uniform mem access
sockets : number of CPU socket per node
cores : number of core per socket
threads : number of threads per core
which does not work well for NUMA topologies where each node does not
consist of integral number of CPU sockets.
We also have VIR_NODEINFO_MAXCPUS macro in public libvirt.h which
computes maximum number of CPUs as (nodes * sockets * cores * threads).
As a result, we can't just change sockets to report total number of
sockets instead of sockets per node. This would probably be the easiest
since I doubt anyone is using the field directly. But because of the
macro, some apps might be using sockets indirectly.
This patch leaves sockets to be the number of CPU sockets per node (and
fixes qemu driver to comply with this) on machines where sockets can be
divided by nodes. If we can't divide sockets by nodes, we behave as if
there was just one NUMA node containing all sockets. Apps interested in
NUMA should consult capabilities XML, which is what they probably do
anyway.
This way, the only case in which apps that care about NUMA may break is
on machines with funky NUMA topology. And there is a chance libvirt
wasn't able to start any guests on those machines anyway (although it
depends on the topology, total number of CPUs and kernel version).
Nothing changes at all for apps that don't care about NUMA.
security_context_t happens to be a typedef for char*, and happens to
begin with a string usable as a raw context string. But in reality,
it is an opaque type that may or may not have additional information
after the first NUL byte, where that additional information can
include pointers that can only be freed via freecon().
Proof is from this valgrind run of daemon/libvirtd:

virConnectClose calls virUnrefConnect which in turn closes
all open drivers when the refcount of that connection dropped
to zero. This works fine when you free all other objects that
hold a ref to the connection before you close it, because in
this case virUnrefConnect is the one that removes the last
ref to the connection.
But it doesn't work when you close the connection first before
freeing the other objects. This is because the other virUnref*
functions call virReleaseConnect when they detect that the
connection's refcount dropped to zero. In this case another
virUnref* function (different from virUnrefConnect) removes the
last ref to the connection. This results in not closing the
open drivers and leaking things that should have been cleaned
up in the driver close functions.
To fix this move the driver close calls to virReleaseConnect.
Except LXC and UML driver, implementations of all other drivers
simply return 0, because these drivers doesn't have config both
in memory and on disk, no need to track if the domain of these

gnulib wraps Windows' SOCKET handle based send() and recv() functions
into file descriptor based ones that are used in libvirt.
Even though GnuTLS is using gnulib too, it explicitly doesn't use
gnulib's replacement functions on Windows. By default GnuTLS uses the
SOCKET handle based send() and recv(). This makes gnutls_handshake()
fail internally with a WSAENOTSOCK error because libvirt passes a
file descriptor; GnuTLS needs the SOCKET handle.
To avoid this mismatch make sure that GnuTLS uses gnulib's replacment
functions, by setting custom pull() and push() functions for GnuTLS.
The stdio.h header has a function called 'remove' declared. This

The SCSI volumes currently get a name like '17:0:0:1' based
on $host:$bus:$target:$lun. The names are intended to be unique
per pool and stable across pool restarts. The inclusion of the
$host component breaks this, because the $host number for iSCSI
pools is dynamically allocated by the kernel at time of login.
This changes the name to be 'unit:0:0:1', ie removes the leading
host component. The 'unit:' prefix is just to ensure the volume
name doesn't start with a number and make it clearer when seen
out of context.
* src/storage/storage_backend_scsi.c: Improve volume name
field value stability and uniqueness
Many operations are not valid on inactive storage pools. The
storage driver is currently returning VIR_ERR_INTERNAL_ERROR
in these cases, rather than the more suitable error code
VIR_ERR_OPERATION_INVALID
* src/storage/storage_driver.c: Fix error code when pool
is not active
When libvirt starts up all storage pools default to the inactive
state, even if the underlying storage is already active on the
host. This introduces a new API into the internal storage backend
drivers that checks whether a storage pool is already active. If
the pool is active at libvirtd startup, the volume list will be
immediately populated.
* src/storage/storage_backend.h: New internal API for checking
storage pool state

src/storage/storage_backend_scsi.c: Add checks for pool state
Since the previous patch added support for parsing the output of
the 'sendtargets' command, it is now trivial to support the
storage pool discovery API.
Given a hostname and optional portnumber and initiator IQN,
the code can return a full list of storage pool source docs,
each one representing a iSCSI target.
* src/storage/storage_backend_iscsi.c: Wire up target
auto-discovery
The Linux iSCSI initiator toolchain has the dubious feature that
if you ever run the 'sendtargets' command to merely query what
targets are available from a server, the results will be recorded
in /var/lib/iscsi. Any time the '/etc/init.d/iscsi' script runs
in the future, it will then automatically login to all those
targets. /etc/init.d/iscsi is automatically run whenever a NIC
comes online.
So from the moment you ask a server what targets are available,
your client will forever more automatically try to login to all
targets without ever asking if you actually want it todo this.
To stop this stupid behaviour, we need to run
iscsiadm --portal $PORTAL --target $TARGET
--op update --name node.startup --value manual
For every target on the server.
* src/storage/storage_backend_iscsi.c: Disable automatic login
for targets found as a result of a 'sendtargets' command
The following series of patches are adding significant
extra functionality to the iSCSI driver. THe current
internal helper methods are not sufficiently flexible
to cope with these changes. This patch refactors the
code to avoid needing to have a virStoragePoolObjPtr
instance as a parameter, instead passing individual
target, portal and initiatoriqn parameters.
It also removes hardcoding of port 3260 in the portal
address, instead using the XML value if any.
* src/storage/storage_backend_iscsi.c: Refactor internal
helper methods
The XML docs describe a 'port' attribute for the
storage source <host> element, but the parser never
handled it.
* docs/schemas/storagepool.rng: Define port attribute
* src/conf/storage_conf.c: Add missing parsing/formatting
of host port number
* src/conf/storage_conf.h: Remove bogus/unused 'protocol' field
When running non-root, the QEMU log file is usually opened with
truncation, since there is no logrotate for non-root usage.
This means that when libvirt logs the shutdown timestamp, the
log is accidentally truncated
* src/qemu/qemu_driver.c: Never truncate log file with shutdown
message
The QEMU logger appends a ':' to the timestamp when it deems
it neccessary, so the virTimestamp API should not duplicate
this
* src/util/util.c: Remove trailing ':' from timestamp
Everytime a public API returns an error, libvirtd pollutes
syslog with that error message. Reduce the error logging
level to INFO so these don't appear by default.
* src/util/virterror.c: Log all errors at INFO
The virFork call resets all logging handlers that may have been
set. Re-enable them after fork in virExec, so that env variables
fir LIBVIRT_LOG_OUTPUTS and LIBVIRT_LOG_FILTERS take effect
until the execve()
* src/util/util.c: Preserve logging in child in virExec
To allow messages from different threads to be untangled,
include an integer thread identifier in log messages.
* src/util/logging.c: Include thread ID
* src/util/threads.h, src/util/threads.h, src/util/threads-pthread.c:
Add new virThreadSelfID() function
* configure.ac: Check for sys/syscall.h
Do this by adding a helper function to get the persistent domain config. This
should be useful for other functions that may eventually want to alter
the persistent domain config (attach/detach device). Also make similar changes
to the test drivers setvcpus command.
A caveat is that the function will return the running config for a transient
domain, rather than error. This simplifies callers, as long as they use
other methods to ensure the guest is persistent.
Doing 'virsh setvcpus $vm --config 10' doesn't check the value against the
domains maxvcpus value. A larger value for example will prevent the guest
from starting.
Also make a similar change to the test driver.
The current semantics of non-persistent hotplug/update are confusing: the
changes will persist as long as the in memory domain definition isn't
overwritten. This means hotplug changes stay around until the domain is
redefined or libvirtd is restarted.
Call virDomainObjSetDefTransient at VM startup, so that we properly discard
hotplug changes when the VM is shutdown.
This function sets the running domain definition as transient, by reparsing
the persistent config and assigning it to newDef. This ensures that any
changes made to the running definition and not the persistent config are
discarded when the VM is shutdown.
This patch makes two corrections to the newly-added QED support patch series:

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

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.
Rather than only cleaning any remaining ebtables rules, also clean those applied to iptables and ip6tables when detecting the IP address of an interface. Previous applied iptables rules may hinder DHCP packets.
Similarly to deprecating close(), I am now deprecating fclose() and
introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with
VIR_FDOPEN().
Most of the files are opened in read-only mode, so usage of
VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write
mode already had the fclose()< 0 check and I converted those to
VIR_FCLOSE()< 0.
I did not find occurrences of possible double-closed files on the way.
Currently only support domain start and shutdown, for domain start,
record timestamp before the qemu command line, and for domain shutdown,
just say it's shutting down with timestamp.

This is more flexible regarding the location of the python binary
but doesn't allow to pass the -u flag. The -i flag can be passed

This fixes a problem with the esx_vi_generator.py on FreeBSD.
This makes the storage driver fail when the connection is
opened with the VIR_CONNECT_RO flag, resulting in a read-only
connection with no storage driver.
In a first step I am converting the netlink message construction in
macvtap code to use libnl. It's pretty much a 1:1 conversion except that
now the message needs to be allocated and deallocated.
When <uuid> is not in the XML, a virUUIDGenerate() ends up being called which
is unnecessary and can lead to crashes if /dev/urandom isn't available
because virRandomInitialize() is not called within virt-aa-helper. This patch
adds verify_xpath_context() and updates caps_mockup() to use it.

If virDomainAttachDevice() was called with an image that was located
on a root-squashed NFS server, and in a directory that was unreadable
by root on the machine running libvirtd, the attach would fail due to
an attempt to change the selinux label of the image with EACCES (which
isn't covered as an ignore case in SELinuxSetFilecon())
NFS doesn't support SELinux labelling anyway, so we mimic the failure
handling of commit 93a18bbafa, which
just ignores the errors if the target is on an NFS filesystem (in
SELinuxSetSecurityAllLabel() only, though.)
This can be seen as a follow-on to commit
347d266c51, which ignores file open
failures of files on NFS that occur directly in
virDomainDiskDefForeachPath() (also necessary), but does not ignore
failures in functions that are called from there (eg
SELinuxSetSecurityFileLabel()).

To avoid the need for duplicating implementations of virStream
drivers, provide a generic implementation that can handle any
FD based stream. This code is copied from the existing impl
in the QEMU driver, with the locking moved into the stream
impl, and addition of a read callback

* daemon/remote.c: Server side impl

To enable virsh console (or equivalent) to be used remotely
it is necessary to provide remote access to the /dev/pts/XXX
pseudo-TTY associated with the console/serial/parallel device
in the guest. The virStream API provide a bi-directional I/O
stream capability that can be used for this purpose. This
patch thus introduces a virDomainOpenConsole API that uses
the stream APIs.

The current remote driver code for streams only supports
blocking I/O mode. This is fine for the usage with migration
but is a problem for more general use cases, in particular
bi-directional streams.
This adds supported for the stream callbacks and non-blocking
I/O. with the minor caveat is that it doesn't actually do
non-blocking I/O for sending stream data, only receiving it.
A future patch will try to do non-blocking sends, but this is
quite tricky to get right.

v2: Change flag name, bool cleanups
I am trying to use a qcow image with libvirt where the backing 'file' is a
qemu-nbd server. Unfortunately virDomainDiskDefForeachPath() assumes that
backingStore is always a real file so something like 'nbd:0:3333' is rejected
because a file with that name cannot be accessed. Note that I am not worried
about directly using nbd images. That would require a new disk type with XML
markup, etc. I only want it to be permitted as a backingStore
The following patch implements danpb's suggestion:
> I think I'm inclined to push the logic for skipping NBD one stage higher.

xencapstest calls xenHypervisorMakeCapabilitiesInternal with conn == NULL
which calls xenDaemonNodeGetTopology with conn == NULL when a recent
enough Xen was detected (sys_interface_version >= SYS_IFACE_MIN_VERS_NUMA).
But xenDaemonNodeGetTopology insists in having conn != NULL and fails,
because it expects to be able to talk to an actual xend.
We cannot do that in a 'make check' test. Therefore, only call the xend

* src/qemu/qemu_conf.h: Flag for QXL support
* src/qemu/qemu_conf.c: Probe for '-vga qxl' support and implement it
* tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c,
tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.args,
tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.xml: Test
case for generating spice args with RHEL6 kvm
This adds an element
<graphics type='spice' port='5903' tlsPort='5904' autoport='yes' listen='127.0.0.1'/>
This is the bare minimum that should be exposed in the guest
config for SPICE. Other parameters are better handled as per
host level configuration tunables
* docs/schemas/domain.rng: Define the SPICE <graphics> schema
* src/domain_conf.h, src/domain_conf.c: Add parsing and formatting
for SPICE graphics config
* src/qemu_conf.c: Complain about unsupported graphics types
* src/qemu_conf.c: Add dummy entry in enumeration
* docs/schemas/domain.rng: Add 'qxl' as a type for the <video> tag
* src/domain_conf.c, src/domain_conf.h: Add QXL to video type
enumerations
