This fixes a leak described in

   https://bugzilla.redhat.com/show_bug.cgi?id=590073

xenUnifiedDomainInfoList has a pointer to a list of pointers to
xenUnifiedDomain. We were freeing up all the domains, but neglecting
to free the list.

This was found by Paolo Bonzini <pbonzini@redhat.com>.

lxcStartup forgot to call lxcAutostartConfigs. Fix it.

This patch should fix https://bugzilla.redhat.com/show_bug.cgi?id=589863 .

Move virDomainChrTargetTypeToString out of the #ifndef PROXY
block, because it's used outside of it.

If detecting the FLR flag of a pci device fails, then we
could run into the situation of trying to close a file
descriptor twice, once in pciInitDevice() and once in pciFreeDevice().
Fix that by removing the pciCloseConfig() in pciInitDevice() and
just letting pciFreeDevice() handle it.

Thanks to Chris Wright for pointing out this problem.

While we are at it, fix an error check.  While it would actually
work as-is (since success returns 0), it's still more clear to
check for < 0 (as the rest of the code does).

Enable specifying a virtio console device with:

<console type='pty'>
  <target type='virtio'/>
</console>

All <console> devices now export a <target> type attribute. QEMU defaults
to 'serial', UML defaults to 'uml, xen can be either 'serial' or 'xen'
depending on fullvirt. Understandably there is lots of test fallout.

This will be used to differentiate between a serial vs. virtio console for
QEMU.

targetType only tracks the actual <target> format we are parsing. Currently
we only fill abide this value for channel devices.
Signed-off-by: NCole Robinson <crobinso@redhat.com>

There is actually a difference between the character device type (serial,
parallel, channel, ...) and the target type (virtio, guestfwd). Currently
they are awkwardly conflated.

Start to pull them apart by renaming targetType -> deviceType. This is
an entirely mechanical change.

During function test of the 802.1Qbg implementation in lldpad we came
across a small problem in the handling of the netlink message
corresponding to PORT_PROFILE_RESPONSE_INPROGRESS. This should not
result in returning the default rc=1.

- src/util/macvtap.c: fix getPortProfileStatus() to return 0 in that
  case and also fix an indentation problem

This would have detected the bug in commit 38ad33931 (Aug 09), which
we missed until commit f828ca35 (Jul 10); over 11 months later.

However, on Fedora 13, it also triggers LOTS of warnings from
the libcurl-devel header for two files:

esx/esx_vi.c: In function 'esxVI_CURL_Perform':
esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
...
xenapi/xenapi_driver.c: In function 'call_func':
xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
...

libcurl allows to disable the type-checking code that triggers those
warnings, along with the reduction in type-safety of calls to some
libcurl functions. I figure this is worth the improved compiler
checking throughout the rest of libvirt.

* acinclude.m4 (--enable-compile-warnings=error): Add -Wlogical-op.
* configure.ac: Add -DCURL_DISABLE_TYPECHECK to LIBCURL_CFLAGS to
avoid compilation warning.

QEMU has had two different syntax for disk cache options

 Old: on|off
 New: writeback|writethrough|none

QEMU recently added another 'unsafe' option which broke the
libvirt check. We can avoid this & future breakage, if we
do a negative check for the old syntax, instead of a positive
check for the new syntax

* src/qemu/qemu_conf.c: Invert cache option check

Add a new element to the <os> block:

  <bootmenu enable="yes|no"/>

Which maps to -boot,menu=on|off on the QEMU command line.

I decided to use an explicit 'enable' attribute rather than just make the
bootmenu element boolean. This allows us to treat lack of a bootmenu element
as 'use hypervisor default'.

Since DV recommended keeping the build instructions distributed with the
source, move them from the old FAQ to the downloads page.

Throw an explicit error if multiple graphics devices are specified, or
an unsupported type is specified (rdp).

When only client parts of libvirt are installed (i.e., no libvirtd
daemon), libvirt-guests init script in its default configuration would
throw seriously looking errors during host shutdown:

Running guests on default URI: error: unable to connect to
'/var/run/libvirt/libvirt-sock', libvirtd may need to be started: No
such file or directory
error: failed to connect to the hypervisor

This patch changes the script to print rather harmless message in that
situation:

Running guests on default URI: libvirtd not installed; skipping this
URI.

Some buggy PCI devices actually support FLR, but
forget to advertise that fact in their PCI config space.
However, Virtual Functions on SR-IOV devices are
*required* to support FLR by the spec, so force has_flr
on if this is a virtual function.

After the recent libvirt-qemu library addition, VPATH builds fail with:

  CC     libvirt_qemu_la-libvirt-qemu.lo
In file included from ../../src/libvirt-qemu.c:29:
../../include/libvirt/libvirt-qemu.h:17:22: error: libvirt.h: No such file or directory
...
  CCLD   libvirt-qmeu.la
/usr/bin/ld: cannot open linker script file libvirt_qemu.syms: No such file or directory

This fixes both issues (there are still some documentation VPATH issues,
but those don't show up with 'make check').

* configure.ac (LIBVIRT_QEMU_SYMBOL_FILE): While libvirt.syms is
generated and lives in $(builddir), libvirt_qemu.syms is static
and lives in $(srcdir).
* include/libvirt/libvirt-qemu.h (includes): Pull in libvirt.h via
the public location, since this is a public header.

When doing a PCI secondary bus reset, we must be sure that there are no
active devices on the same bus segment.  The active device tracking is
designed to only track host devices that are active in use by guests.
This ignores host devices that are actively in use by the host.  So the
current logic will reset host devices.

Switch this logic around and allow sbus reset when we are assigning all
devices behind a bridge to the same guest at guest startup or as a result
of a single attach-device command.

* src/util/pci.h: change signature of pciResetDevice to add an
  inactive devices list
* src/qemu/qemu_driver.c src/xen/xen_driver.c: use (or not) the new
  functionality of pciResetDevice() depending on the place of use
* src/util/pci.c: implement the interface and logic changes

- src/qemu/qemu_driver.c: Eliminate code duplication by using the new
  helpers qemuPrepareHostdevPCIDevices and qemuDomainReAttachHostdevDevices.
  This reduces the number of open coded calls to pciResetDevice.

- src/qemu/qemu_driver.c: These new helpers take hostdev list and count
  directly rather than getting them indirectly from domain definition.
  This will allow reuse for the attach-device case.

- src/qemu/qemu_driver.c: Update qemuGetPciHostDeviceList to take a
  hostdev list and count directly, rather than getting this indirectly
  from domain definition. This will allow reuse for the attach-device case.

Also accept version > 4.1, but output a warning.

Add a pointer to the primary context of a connection and use it in all
driver functions that don't dependent on the context type. This includes
almost all functions that deal with a virDomianPtr. Therefore, using
a vpx:// connection allows you to perform all the usual domain related
actions like start, destroy, suspend, resume, dumpxml etc.

Some functions that require an explicitly specified ESX server don't work
yet. This includes the host UUID, the hostname, the general node info, the
max vCPU count and the free memory. Also not working yet are migration and
defining new domains.

Since 070f6100 the vcenter query
parameter has been ignored, because the refactoring to use
esxUtil_ParseQuery was incomplete. This effectively broke migration,
because the vcenter query parameter is essential for a migration.

This works for file-backed SCSI disk device with a datastore
related source path.

Since 68719c4b virSecurityDriverStartup
takes and additional parameter to control disk format probing.

Pass false as third parameter.

Commit 68719c4b added the disk format
probing option. This makes virt-aa-helper-test fail because the domain
config didn't specifiy the disk format and it didn't pass '-p 1' to
virt-aa-helper to allow disk format probing.

Specify the disk format in the domain config. Pass the '-p 1' option
to virt-aa-helper for the test case with two disks. This way this test
also covers this new option.

Commit 68719c4b added the
p option to control disk format probing, but it wasn't added
to the getopt_long optstring parameter.

Add the p option to the getopt_long optstring parameter.

Commit a8853344 added this
function and wrapped vah_add_file in it. vah_add_file may
return -1, 0, 1. It returns 1 in case the call to valid_path
detects a restricted file. The original code treated a return
value != 0 as error. The refactored code treats a return
value < 0 as error. This triggers segfault in virt-aa-helper
and breaks virt-aa-helper-test for the restricted file tests.

Make sure that add_file_path returns -1 on error.

virt-aa-helper used to ignore errors when opening files.
Commit a8853344 refactored
the related code and changed this behavior. virt-aa-helper
didn't ignore open errors anymore and virt-aa-helper-test
fails.

Make sure that virt-aa-helper ignores open errors again.

* src/remote_protocol-structs: Tweak to match intentional type
change (with no ABI change) in remote protocol.

Thanks to DV for knocking together the Relax-NG changes
quickly for me.

Changes since v1:
 - Change the domain.rng to correspond to the new schema
 - Don't allocate caps->ns in testQemuCapsInit since it is a static table

Changes since v2:
 - Change domain.rng to add restrictions on allowed environment names

Changes since v3:
 - Remove a bogus comment in the tests
