Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

Commit 861d40565 added code (my personal change to "clean up" the
submitter's code, *not* the fault of the submitter) that dereferenced
virtVlan without first checking for NULL. This patch fixes that and,
as part of the fix, cleans up some unnecessary obtuseness.
This patch adds functionality to allow libvirt to configure the
'native-tagged' and 'native-untagged' modes on openvswitch networks.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
Add utility functions for Open vSwitch to both save
per-port data before a live migration, and restore the
per-port data after a live migration.

If a network or interface is configured to use Open vSwitch, but
ovs-vswitchd (the Open vSwitch database service) isn't running, the
ovs-vsctl add-port/del-port commands will hang indefinitely rather
than returning an error. There is a --nowait option, but that appears
to have no effect on add-port and del-port commands, so instead we add
a --timeout=5 to the commands - they will retry for up to 5 seconds,
then fail if there is no response.
The introduction of the new VLAN code, along with the fix
from 5e465df6be, caused the
addition of OVS ports to fail with the following message:
ovs-vsctl: 00002|vsctl|ERR|: missing column name
This fix takes into account the VLAN arguments are optional,
and correctly sets up the command line to run the "ovs-vsctl"
command to add ports to the OVS bridge.

Fixup buffer usage when handling VLANs. Also fix the logic
used to determine if the virNetDevVlanPtr is valid or not.
Fixes crashes in the latest code when using Open vSwitch
virtualports.

Add the ability to support VLAN tags for Open vSwitch virtual port
types. To accomplish this, modify virNetDevOpenvswitchAddPort and
virNetDevTapCreateInBridgePort to take a virNetDevVlanPtr
argument. When adding the port to the OVS bridge, setup either a
single VLAN or a trunk port based on the configuration from the
virNetDevVlanPtr.

virNetDevVPortProfile has (had) a type field that can be set to one of
several values, and a union of several structs, one for each
type. When a domain's interface object is of type "network", the
domain config may not know beforehand which type of virtualport is
going to be provided in the actual device handed down from the network
driver at runtime, but may want to set some values in the virtualport
that may or may not be used, depending on the type. To support this
usage, this patch replaces the union of structs with toplevel fields
in the struct, making it possible for all of the fields to be set at
the same time.

Introduce new members in the virMacAddr 'class'
- virMacAddrSet: set virMacAddr from a virMacAddr
- virMacAddrSetRaw: setting virMacAddr from raw 6 byte MAC address buffer
- virMacAddrGetRaw: writing virMacAddr into raw 6 byte MAC address buffer
- virMacAddrCmp: comparing two virMacAddr
- virMacAddrCmpRaw: comparing a virMacAddr with a raw 6 byte MAC address buffer
then replace raw MAC addresses by replacing
- 'unsigned char *' with virMacAddrPtr
- 'unsigned char ... [VIR_MAC_BUFLEN]' with virMacAddr
and introduce usage of above functions where necessary.
This patch will allow OpenFlow controllers to identify which interface
belongs to a particular VM by using the Domain UUID.
ovs-vsctl get Interface vnet0 external_ids
{attached-mac="52:54:00:8C:55:2C", iface-id="83ce45d6-3639-096e-ab3c-21f66a05f7fa", iface-status=active, vm-id="142a90a7-0acc-ab92-511c-586f12da8851"}
V2 changes:
Replaced vm-uuid with vm-id. There was a discussion in Open vSwitch
mailinglist that we should stick with the same DB key postfixes for the
sake of consistency (e.g iface-id, vm-id ...).
The indentation on the final lines of the function was off by four
spaces, making me wonder for a second if there was something
missing. (There wasn't.)
This patch allows libvirt to add interfaces to already
existing Open vSwitch bridges. The following syntax in
domain XML file can be used:
<interface type='bridge'>
<mac address='52:54:00:d0:3f:f2'/>
<source bridge='ovsbr'/>
<virtualport type='openvswitch'>
<parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
</virtualport>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
or if libvirt should auto-generate the interfaceid use
following syntax:
<interface type='bridge'>
<mac address='52:54:00:d0:3f:f2'/>
<source bridge='ovsbr'/>
<virtualport type='openvswitch'>
</virtualport>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
It is also possible to pass an optional profileid. To do that
use following syntax:
<interface type='bridge'>
<source bridge='ovsbr'/>
<mac address='00:55:1a:65:a2:8d'/>
<virtualport type='openvswitch'>
<parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'
profileid='test-profile'/>
</virtualport>
</interface>
To create Open vSwitch bridge install Open vSwitch and
run the following command:
ovs-vsctl add-br ovsbr
