Detected by clang.  POSIX requires that the second argument to
va_start be the name of the last variable; and in some implementations,
passing *path instead of path would dereference bogus memory instead
of pulling arguments off the stack.

* src/util/util.c (virBuildPathInternal): Use correct argument to

Support for live migration between hosts that do not share storage was
added to qemu-kvm release 0.12.1.
It supports two flags:
-b migration without shared storage with full disk copy
-i migration without shared storage with incremental copy (same base image
shared between source and destination).

I tested the live migration without shared storage (both flags) for native
and p2p with and without tunnelling.  I also verified that the fix doesn't
affect normal migration with shared storage.

Wipe generated interface target only when reading configuration of
inactive domains.

Report VIR_ERR_OPERATION_INVALID when operation which requires running
domain is called on inactive domain and vice versa.

Consistently use virDomainFindByUUID instead of virDomainFindByID and
virDomainFindByName and report VIR_ERR_NO_DOMAIN when domain cannot be
found.

Add an empty body for virCondWaitUntil and move virPipeReadUntilEOF
out of the '#ifndef WIN32' block, because it compiles fine with MinGW
in combination with gnulib.

Necessary on cygwin, where uid_t and gid_t are 4-byte long rather
than int, causing gcc -Wformat warnings.

* src/util/util.c (virFileOperationNoFork, virDirCreateNoFork)
(virFileOperation, virDirCreate, virGetUserEnt): Cast uid_t and
gid_t before passing to printf.
* .gitignore: Ignore Windows executables.

When a filter is updated, only those interfaces must have their old
rules cleared that either reference the filter directly or indirectly
through another filter. Remember between the different steps of the
instantiation of the filters which interfaces must be skipped. I am
using a hash map to remember the names of the interfaces and store a
bogus pointer to ~0 into it that need not be freed.

For the decision on whether to instantiate the rules, the check for a
pending IP address learn request is not sufficient since then only the
thread could instantiate the rules. So, a boolean needs to be passed
when the thread instantiates the filter rules late and the IP address
learn request is still pending in order to override the check for the
pending learn request. If the rules are to be updated while the thread
is active, this will not be done immediately but the thread will do that
later on.

WIN32 is always defined when __MINGW32__ is defined, but the
converse is not true.  WIN32 is more generic, if someone were
to ever attempt porting to a microsoft compiler.  This does
not affect Cygwin, which intentionally does not define WIN32.

generic flag macro.

Also do some indentation clean up.

[Error message]
error: Failed to start domain lxc_test1
error: internal error Failed to create veth device pair: 512

The reason of the failure is that lxc driver unexpectedly re-uses
an auto-assigned veth name and tries to create the created veth
again. The failure will happen when a domain has multiple network
interfaces and the names of those are not specified in XML.

The patch fixes the problem by resetting buffers of veth names
in every iteration of creating veth.

* src/lxc/lxc_driver.c: prevent re-using auto-assigned veth name
  Reported by Kumar L Srikanth-B22348.

<hostdev> address parsing previously attempted to detect the number
base: currently it is hardcoded to base 16, which can break PCI
assignment via virt-manager. Revert to the previous behavior.

This introduces a new event type

   VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON

This event is the same as the previous VIR_DOMAIN_ID_IO_ERROR
event, but also includes a string describing the cause of
the event.

Thus there is a new callback definition for this event type

typedef void (*virConnectDomainEventIOErrorReasonCallback)(virConnectPtr conn,
                                                           virDomainPtr dom,
                                                           const char *srcPath,
                                                           const char *devAlias,
                                                           int action,
                                                           const char *reason,
                                                           void *opaque);

Prevent updating and tearing down of filter while the IP
address learning thread is running and has its own filtering
rules applied.

Introduce a function to notify the IP address learning
thread to terminate and thus release the lock on the interface.
Notify the thread before grabbing the lock on the interface
and tearing down the rules. This prevents a 'virsh destroy' to
tear down the rules that the IP address learning thread has
applied.

The functions invoked by the IP address learning thread
that apply some basic filtering rules did not clean up
any previous filtering rules that may still be there
(due to a libvirt restart for example). With the
patch below all the rules are cleaned up first.

Also, I am introducing a function to drop all traffic
in case the IP address learning thread could not apply
the rules.

* src/util/util.c: as it's used for checking things like .iso suffixes

The local DHCP server on virtbr0 sends DHCP ACK messages when a VM is
started and requests an IP address while the initial DHCP lease on the
VM's MAC address hasn't expired. So, also pick the IP address of the VM
if that type of message is seen.
Thanks to Gerhard Stenzel for providing a test case for this.

Changes from V1 to V2:
- cleanup: replacing DHCP option numbers through constants

* src/qemu/qemu_driver.c (qemudDomainSaveFlag): Remove dead store to "rc".

When using -device syntax, the IO event will have a different

qemuDomainPCIAddressSetFree was freeing up the hash
table for the pci addresses, but not freeing up the addr
structure.  Looking over the callers of this function, it
seems like they expect it to also free up the structure,
so do that here.

We were over-writing a pointer without freeing it in
case of a disk device, leading to a memory leak.

When building on Ubuntu with make -j3 (or more), it would always
fail when trying to build virt-aa-helper.  I'm not an expert in
automake by any means, but I think the entry for virt-aa-helper
is mis-using LDADD; it shouldn't be putting direct paths to
libvirt_conf.la and libvirt_util.la, but instead referencing those
names.  With this patch in place, I'm able to successfully build
on Ubuntu 9.04 with make -j3.

The previous commit changes a goto from 'endjob' to 'cleanup',
leaving the endjob label unused. Remove it to avoid compile
warning.

* src/qemu/qemu_driver.c: Remove 'endjob' label

* src/qemu/qemu_driver.c (qemuDomainSnapshotCreateXML): When setting
"vm" to NULL, jump over vm-dereferencing code to "cleanup".
(qemuDomainRevertToSnapshot): Likewise.

* src/qemu/qemu_driver.c (qemudDomainCreate): Goto cleanup,
not "endjob", since we know "vm" is already NULL.  No semantic change.

use /var/lib/libvirt/dnsmasq since /var/lib/libvirt/network is
unreadable by the dnsmasq binary

* src/network/bridge_driver.c: update DNSMASQ_STATE_DIR
* src/Makefile.am: create it on make install
* libvirt.spec.in: take the new directory into account
