39b6265476 qemu: setvcpus: Simplify altering the persistent config
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.

08a72a7d89 domain_conf: Add virDomainObjSetDefTransient
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.

9c7c4a4fc5 Allow non-file disk backingStores
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.
> I'd rather expect virStorageFileGetMetadata() to return all backing
> stores, even if not files. The virDomainDiskDefForeachPath() method
> should definitely ignore non-file backing stores though.
>
> So what I'm thinking is to extend the virStorageFileMetadata struct and
> just add a 'bool isFile' field to it. Default this field to true, unless
> you see the prefix of nbd: in which case set it to false. The
> virDomainDiskDefForeachPath() method can then skip over any backing
> store with isFile == false

c4bd44d927 macvtap: libvirtd forgot macvtap dev name when restarted
During a shutdown/restart cycle libvirtd forgot the macvtap device name that it had created on behalf of a VM so that a stale macvtap device remained on the host when the VM terminated. Libvirtd has to actively tear down a macvtap device and it uses its name for identifying which device to tear down.

The solution is to not blank out the <target dev='...'/> completely, but only blank it out on VMs that are not active. So, if a VM is active, the device name makes it into the XML and is also being parsed. If a VM is not active, the device name is discarded.

a8ae7d19f4 Remove all use of inet_pton and inet_ntop
The  inet_pton and inet_ntop functions are obsolete, replaced
by getaddrinfo+getnameinfo with the AI_NUMERICHOST flag set.
These can be accessed via the virSocket APIs.

The bridge.c code had methods for fetching the IP address of
a bridge which used inet_ntop. Aside from the use of inet_ntop
these methods are broken, because a NIC can have multiple
addresses and this only returns one address. Since the methods
are never used, just remove them.

4617eedfae vcpu: support maxvcpu in domain_conf
Although this patch adds a distinction between maximum vcpus and

f04de501bc Introduce VIR_CLOSE to be used rather than close()
Since bugs due to double-closed file descriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here.

There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were.

I also dare to declare close() as being deprecated in libvirt code base (HACKING).

4435f3c477 nwfilter: resolve deadlock between VM ops and filter update
This is from a bug report and conversation on IRC where Soren reported that while a filter update is occurring on one or more VMs (due to a rule having been edited for example), a deadlock can occur when a VM referencing a filter is started.

The problem is caused by the two locking sequences of

qemu driver, qemu domain, filter             # for the VM start operation
filter, qemu_driver, qemu_domain            # for the filter update operation

that obviously don't lock in the same order. The problem is the 2nd lock sequence. Here the qemu_driver lock is being grabbed in qemu_driver:qemudVMFilterRebuild()

The following solution is based on the idea of trying to re-arrange the 2nd sequence of locks as follows:

qemu_driver, filter, qemu_driver, qemu_domain

and making the qemu driver recursively lockable so that a second lock can occur, this would then lead to the following net-locking sequence

qemu_driver, filter, qemu_domain

where the 2nd qemu_driver lock has been ( logically ) eliminated.

The 2nd part of the idea is that the sequence of locks (filter, qemu_domain) and (qemu_domain, filter) becomes interchangeable if all code paths where filter AND qemu_domain are locked have a preceding qemu_domain lock that basically blocks their concurrent execution

So, the following code paths exist towards qemu_driver:qemudVMFilterRebuild where we now want to put a qemu_driver lock in front of the filter lock.

-> nwfilterUndefine()   [ locks the filter ]
    -> virNWFilterTestUnassignDef()
        -> virNWFilterTriggerVMFilterRebuild()
            -> qemudVMFilterRebuild()

-> nwfilterDefine()
    -> virNWFilterPoolAssignDef() [ locks the filter ]
        -> virNWFilterTriggerVMFilterRebuild()
            -> qemudVMFilterRebuild()

-> nwfilterDriverReload()
    -> virNWFilterPoolLoadAllConfigs()
        ->virNWFilterPoolObjLoad()
            -> virNWFilterPoolAssignDef() [ locks the filter ]
                -> virNWFilterTriggerVMFilterRebuild()
                    -> qemudVMFilterRebuild()

-> nwfilterDriverStartup()
    -> virNWFilterPoolLoadAllConfigs()
        ->virNWFilterPoolObjLoad()
            -> virNWFilterPoolAssignDef() [ locks the filter ]
                -> virNWFilterTriggerVMFilterRebuild()
                    -> qemudVMFilterRebuild()

Qemu is not the only driver using the nwfilter driver, but also the UML driver calls into it. Therefore qemuVMFilterRebuild() can be exchanged with umlVMFilterRebuild() along with the driver lock of qemu_driver that can now be a uml_driver. Further, since UML and Qemu domains can be running on the same machine, the triggering of a rebuild of the filter can touch both types of drivers and their domains.

In the patch below I am now extending each nwfilter callback driver with functions for locking and unlocking the (VM) driver (UML, QEMU) and introduce new functions for locking all registered callback drivers and unlocking them. Then I am distributing the lock-all-cbdrivers/unlock-all-cbdrivers call into the above call paths. The last shown callpath starting with nwfilterDriverStart() is problematic since it is initialize before the Qemu and UML drives are and thus a lock in the path would result in a NULL pointer attempted to be locked -- the call to virNWFilterTriggerVMFilterRebuild() is never called, so we never lock either the qemu_driver or the uml_driver in that path. Therefore, only the first 3 paths now receive calls to lock and unlock all callback drivers. Now that the locks are distributed where it matters I can remove the qemu_driver and uml_driver lock from qemudVMFilterRebuild() and umlVMFilterRebuild() and not requiring the recursive locks.

For now I want to put this out as an RFC patch. I have tested it by 'stretching' the critical section after the define/undefine functions each lock the filter so I can (easily) concurrently execute another VM operation (suspend,start). That code is in this patch and if you want you can de-activate it. It seems to work ok and operations are being blocked while the update is being done.
I still also want to verify the other assumption above that locking filter and qemu_domain always has a preceding qemu_driver lock.

79c27a620a allow memballoon type of none to desactivate it
The balloon device is automatically added to qemu guests if supported,
but it may be useful to desactivate it. The simplest to not change the
existing behaviour is to allow
  <memballoon type="none"/>
as an extra option to desactivate it (it is automatically added if the
memballoon construct is missing for the domain).
The following simple patch just adds the extra option and does not
change the default behaviour but avoid creating a balloon device if
type="none" is used.

* docs/schemas/domain.rng: add the extra type attribute value
* src/conf/domain_conf.c src/conf/domain_conf.h: add the extra enum
  value
* src/qemu/qemu_conf.c: if enum is NONE, don't activate the device,
  i.e. don't pass the args to qemu/kvm

CPU definition. Which is right, since guest CPU definitions do not
contain <arch> element. However, if at the same time the root <cpu>

still treat the XML as host CPU. We should rather refuse such invalid

The domain parsing code would auto-add a virtio serial controller

ca1b7cc8e4 macvtap: cannot support target device name
Since the macvtap device needs active tear-down and the teardown logic
is based on the interface name, it can happen that if for example 1 out
of 3 interfaces was successfully created, that during the failure path
the macvtap's target device name is used to tear down an interface that
is doesn't own (owned by another VM).

So, in this patch, the target interface name is reset so that there is
no target interface name and the interface name is always cleared after
a tear down.

a8f75d2c7d vepa: parsing for 802.1Qb{g|h} XML
This patch parses the following two XML descriptions, one for
802.1Qbg and one for 802.1Qbh, and stores the data internally.
The actual triggering of the switch setup protocol has not been
implemented here but the relevant code to do that should go into
the functions associatePortProfileId() and disassociatePortProfileId().

   <interface type='direct'>
      <source dev='eth0.100' mode='vepa'/>
      <model type='virtio'/>
      <virtualport type='802.1Qbg'>
        <parameters managerid='12' typeid='0x123456' typeidversion='1'
         instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/>
      </virtualport>
      <filterref filter='clean-traffic'/>
    </interface>

    <interface type='direct'>
      <source dev='eth0.100' mode='vepa'/>
      <model type='virtio'/>
      <virtualport type='802.1Qbh'>
        <parameters profileid='my_profile'/>
      </virtualport>
    </interface>

I'd suggest to use this patch as a base for triggering the setup
protocol with the 802.1Qb{g|h} switch.

Several rounds of changes were made to this patch. The
following is a list of these changes.
- Renamed structure virVirtualPortProfileDef to virVirtualPortProfileParams
  as per Daniel Berrange's request
- Addressing Daniel Berrange's comments:
 - removing macvtap.h's dependency on domain_conf.h by
   moving the virVirtualPortProfileDef structure into macvtap.h
   and not passing virtDomainNetDefPtr to any functions in
   macvtap.c
- Addressed most of Chris Wright's comments:
  - indicating error in case virtualport XML node cannot be parsed
    properly
  - parsing hex and decimal numbers using virStrToLong_ui() with
    parameter '0' for base
  - tgifname (target interface name) variable wasn't necessary
    to pass to openMacvtapTap function anymore
- assigning the virtual port data structure to the virDomainNetDef
  only if it was previously parsed
- make sure that the error code returned by openMacvtapTap() is a negative n
  in case the associatePortProfileId() function failed.
- renaming vsi in the XML to virtualport
- replace all occurrences of vsi in the source as well
- removing mode and MAC address parameters from the functions that
  will communicate with the hareware diretctly or indirectly
- moving the associate and disassociate functions to the end of the
  file for subsequent patches to easier make them generally available
  for export
- passing the macvtap interface name rather than the link device since
  this otherwise gives funny side effects when using netlink messages
  where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev
  all of a sudden gets the MAC address of the macvtap interface.
- Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case
  we wanted to use hook scripts for the setup and so the setup doesn't fail
  here.
- if instance ID UUID is not supplied it will automatically be generated
  - adapted schema to make instance ID UUID optional
  - added test case
- parser and XML generator have been separated into their own
  functions so they can be re-used elsewhere (passthrough case
  for example)
- Adapted XML parser and generator support the above shown type
  (802.1Qbg, 802.1Qbh).
- Adapted schema to above XML
- Adapted test XML to above XML
- Passing through the VM's UUID which seems to be necessary for
  802.1Qbh -- sorry no host UUID
- adding virtual function ID to association function, in case it's
  necessary to use (for SR-IOV)

018fd697b6 nwfilter: skip some interfaces on filter update
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.

e984019688 domain: Fix PCI address decimal parsing regression
<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.

* src/conf/domain_conf.c: virDomainDevicePCIAddressParseXML, switch to
  virStrToLong_ui(bus, NULL, 0, ...) to autodetect base

34dcbbb470 Add support for another explicit IO error event
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);

This is currently wired up to the QEMU block IO error events

* daemon/remote.c: Dispatch IO error events to client
* examples/domain-events/events-c/event-test.c: Watch for
  IO error events
* include/libvirt/libvirt.h.in: Define new IO error event ID
  and callback signature
* src/conf/domain_event.c, src/conf/domain_event.h,
  src/libvirt_private.syms: Extend API to handle IO error events
* src/qemu/qemu_driver.c: Connect to the QEMU monitor event
  for block IO errors and emit a libvirt IO error event
* src/remote/remote_driver.c: Receive and dispatch IO error
  events to application
* src/remote/remote_protocol.x: Wire protocol definition for
  IO error events

59fe163f2f Clean all tables before applying 'basic' rules
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.

aea68ce906 nwfilter: add support for RAPR protocol
This patch adds support for the RARP protocol. This may be needed due to
qemu sending out a RARP packet (at least that's what it seems to want to
do even though the protocol id is wrong) when migration finishes and
we'd need a rule to let the packets pass.

Unfortunately my installation of ebtables does not understand -p RARP
and also seems to otherwise depend on strings in /etc/ethertype
translated to protocol identifiers. Therefore I need to pass -p 0x8035
for RARP. To generally get rid of the dependency of that file I switch
all so far supported protocols to use their protocol identifier in the
-p parameter rather than the string.

I am also extending the schema and added a test case.

changes from v1 to v2:
- added test case into patch

1b9347b5f1 Fix indentation for storage conf XML
* virStorageEncryptionFormat is called from both
  virDomainDiskDefFormat and virStorageVolTargetDefFormat.  The proper
  indentation in the generated XML depends on the caller.  My earlier
  patch to fix the incorrect indentation for the domain XML broke the
  indentation for the storage XML.  This patch adopts Laine's
  suggestion of requring the caller of virStorageEncryptionFormat to
  provide an unsigned int with the number of spaces the output should
  be indented.  The patch modifies both callers to provide the
  additional argument.

* Add a regression test for the domain XML

* src/conf/domain_conf.c src/conf/storage_conf.c
  src/conf/storage_encryption_conf.c src/conf/storage_encryption_conf.h:
  change the indentation code
