There are a few things to do to achieve this goal:
1. extend current command line syntax of 'virsh attach-interface'
2. extend current command line syntax of 'virt-install'
3. define bandwidth representation in XML format
For 1.
I will change the current command line syntax to:
virsh attach-interface <domain> <type> <source> [--target <target>]
[--mac <mac>] [--script <script>] [--rate <rate-string>]
So that we are able to specify bandwidth as "--rate 100M" in command line, like:
#virsh attach-interface domu bridge bge0 --rate 100M
In this case, bandwidth is specified as an integer with one of the scale
suffixes K, M, or G for Kbps, Mbps, or Gbps.
For 2.
I will add one more option "--rate=rate-string" to current option set of
virt-install command. Users can repeatedly add more than one 'rate' options
to set bandwidth for multiple nic devices respectively, if needed.
For example, with below command line, we start installing a domain with two
nic devices whose bandwidth are set to 100Mb/s and 200Mb/s respectively:
#virt-install -n snv105 -r 2048 -p --file=/root/snv105
--location=/solarisdvd.iso -b bge0 --rate=100M -b bge1 --rate=200M
In this case, bandwidth is specified as an integer with one of the scale
suffixes K, M, or G for Kbps, Mbps, or Gbps.
For 3.
All user specified bandwidth will be represented as part of interface
element currently defined in XML configuration file.
The new format looks like:
<interface type='bridge'>
<source bridge='e1000g1'/>
<flowcontrol>
<rate unit='megabit' period='second' value='100'/>
</flowcontrol>
</interface>
So, I create a new element, "flowcontrol", inside "interface" element. Inside
"flowcontrol", I provide bandwidth by setting "rate" element with three
attributes, "unit", "period" and "value" to express the bandwidth limit.
The supported unit can be 'gigabit', 'megabit' and 'kilobit'.
The supported period can be 'second', 'millisecond' and 'microsecond'.
And value is an integer to express the amount of data in unit allowed to be
transfered in period of time.
More elements can be added inside "flowcontrol" element, if we want to add more
flow control policies in the future.

[libvirt] Adding VirtualBox support to libvirt
by Pritesh Kothari
Hi,
I am in the process of adding support for virtualbox in libvirt.
Basically Virtualbox exports its API through XPCOM. Now to simplify
things I was thinking of using C++ and already existing xpcom component
in virtualbox but since libvirt exports C API i am not sure if i should
use C++ or stick to plain C.
I would like to request the libvirt community for its comment
on this.
Regards,
Pritesh

[libvirt] [PATCH ] (type ioem) adding qemu nic configuration option in to libvirt (XEN)
by Gihan Munasinghe
Guys
I have added a new attribute with with in <interface > tag called "qemu"
which can be either true or false..
Indicating if the user wants XEN to create qeum net device or not.. This
will fix the problem with PV net drivers with XEN..
Check the following examples
e.g 1) Interface tag with qemu attribute set to false
<interface type='bridge' qemu='false'>
<mac address='00:16:3e:00:a5:01'/>
<source bridge='eth0'/>
<target dev='vif1.0'/>
</interface>
qemu-dm output
---------------------
/usr/lib64/xen/bin/qemu-dm -d 60 -domain-name benchmark1 -k en-gb -vnc
0.0.0.0:1 -vcpus 2 -boot c -serial pty -acpi -usb -net none -M xenfv
XEND has configured the hvm guest not to have network card via qemu
e.g 2) Interface tag with qemu attribute set to true with qemu supported
nic model
<interface type='bridge' qemu='true'>
<mac address='00:16:3e:00:a5:01'/>
<source bridge='eth0'/>
<target dev='vif1.0'/>
<model type='e1000'/>
</interface>
qemu-dm output
---------------------
/usr/lib64/xen/bin/qemu-dm -d 61 -domain-name benchmark1 -k en-gb -vnc
0.0.0.0:1 -vcpus 2 -boot c -serial pty -acpi -usb -net
nic,vlan=1,macaddr=00:16:3e:00:a5:01,model=e1000 -net
tap,vlan=1,ifname=tap61.0,bridge=eth0 -M xenfv
Now XEND have configured the hvm guest to have emulated nic of the model
"e1000"
Therefore now, via libvirt configuration I have the ability ask xen to
either to configure qemu network card or not (when I have pv divers
installed with in my VM )
I have attached the patch files, Let me know what you guys think.
Thanks
Gihan

[libvirt] adding tests....
by Jim Meyering
In adding a couple of tests, I noticed that libvirtd --config=no-such
didn't diagnose my mistake.
I fixed that with the first patch below:
diagnose "libvirtd --config=no-such-file"
* qemud/qemud.c (remoteReadConfigFile): Don't return 0 (success)
when the config file is unreadable or nonexistent
Return -1, not 0, upon virConfReadFile failure.
(main): If remote_config_file is not specified via --config(-f),
use the default config file only if it exists. Otherwise,
use /dev/null.
However, that made it so libvirtd gave two diagnostics:
Failed to open file 'no-such': No such file or directory
libvir: Config error : failed to open no-such for reading
The latter part of that patch fixes it like this:
* src/conf.c (virConfReadFile): Don't diagnose virFileReadAll
failure, since it already does that.
Finally, I went to add the two tests,
one to ensure libvirtd --config=no-such-file now fails, as I expected
another to start libvirtd and then run a small pool-related test via
a separate virsh invocation.
But that made me see a bug in tests/Makefile.am:
A missing backslash made it so the virsh-all test wasn't being run.
Easy to fix. But then, I saw when virsh-all runs it generated too
much output, so I did this:
tests: quiet virsh-all
* tests/virsh-all: For now, ignore diagnostics and exit status,
when running all virsh commands.
Finally, here are the two tests:
add tests
* tests/libvirtd-pool: New file.
* tests/libvirtd-fail: New file.
* tests/Makefile.am (test_scripts): Add omitted backslash,
so that the virsh-all test is run.
Add libvirtd-fail and libvirtd-pool.

[libvirt] [PATCH/RFC]: don't ignore errors to save the domain status file
by Guido Günther
Hi,
we currently don't report errors to save qemu's domain status file back
to the caller. That was o.k. as long as the code was there for testing
but now that the XML is being picked up on daemon restart we must
handle these.
The attached patch does that, although I'm not confident that it's
enough. While we return error on device attach/unattach the device
actually got attached/unattached already. Same is true for
suspend/resume.
A better solution would be to write out the new domain status into a
temp file and simply call rename(2) on it when the attach/unattach
succeeds and discard it if it fails. This would minimize the possible
error conditions like disk full, missing permissions to write into that
directory etc. Does this sound reasonable?
O.k. to apply the attached version for now?
Cheers,
-- Guido

[libvirt] RFC: configuring host interfaces with libvirt
by David Lutterkort
For certain applications, we want libvirt to be able to configure host
network interfaces in a variety of ways; currently, we are most
interested in teaching libvirt how to set up ordinary ethernet
interfaces, bridges, bonding and vlan's.
Below is a high-level proposal of how that could be done. Please comment
copiously ;)
1. XML Format
=============
The first question is how the user would describe the host interfaces they
want. Below are some sketches of what an XML representation of the various
kinds of interfaces would look like. This covers the minimal amount of
settings for these to be useful, though I am sure we'll need to add more
over time.
<interface device="eth0" onboot="yes">
<hwaddr>00:19:d2:9f:88:96</hwaddr>
<dhcp peerdns="yes"/>
</interface>
<interface device="eth1" onboot="yes">
<hwaddr>00:19:d2:9f:88:97</hwaddr>
<static ipaddr="192.168.0.5" gateway="192.168.0.1" netmask="255.255.255.0"/>
</interface>
<interface device="eth2" onboot="yes">
<hwaddr>00:19:d2:9f:88:98</hwaddr>
</interface>
<bond name="bond00" onboot="yes" mode="active-backup">
<slave device="eth0" primary="yes"/>
<slave device="eth1"/>
</bond>
<bridge name="br0" stp="off" onboot="yes">
<member device="eth2"/>

<vlan device="eth0" tag="42" reorder_hdr="yes"/>
All of these should also allow a <uuid> element for specifying a uuid; I
omitted that for brevity.
2. API Changes
==============
There are two options for dealing with network interfaces: (1) use the
existing virNetwork* calls or (2) add completely new API calls.
Repurposing existing virNetwork* calls
--------------------------------------
The existing calls map well to the operations we need for managing
interfaces, with a few exceptions:
- virNetworkGetAutostart/SetAutostart: depending on how we implement all
this (see below), 'autostart' might actually mean 'on boot', not 'when
libvirtd starts'
- virNetworkGetBridgeName doesn't make sense for interfaces, and should
return NULL for interfaces
We'll probably also end up adding some functions to query details about an
interface, in particular, a call to see what kind of network/interface a
virNetworkPtr represents
Add completely new virInterface* calls
--------------------------------------
This would add roughly the same API calls as the virNetwork* calls,
i.e. we'd have something like
typedef struct virInterface *virInterfacePtr;
int virInterfaceCreate(virInterfacePtr);
virInterfacePtr virInterfaceCreateXML(..);
...
plus some calls to extract information from a virInterfacePtr
The second option seems cleaner to me and easier to implement, and avoids
any subtle changes in the behavior of existing API, though I don't like
that we'll be adding another 20 or so calls to libvirt's public API, with
attendant churn both in the drivers and in virsh.
3. Implementation
=================
Configuring network interfaces is highly OS and OS-variant/distro
dependant. There are at least two different ways how libvirt can go about
modifying the host to create interfaces:
1. Modify the system's network setup scripts (ifcfg-XXX on RH)
2. Directly use the system's network utilities like ifconfig
3. Rely on NetworkManager (not an option right now, as NM doesn't know
about bridges and the like)
Option (1) saves us from replicating every bit of network setup
functionality that those scripts already have - besides configuring the
interface, we also might have to setup routes, run dhclient etc.
Option (2) would require far fewer backend implementations than (1) - we
should be able to get away with one implementation for Linux, rather than
one for Fedora/RHEL, one for Debian, one for SuSe, three for gentoo
etc.
If we want 'autostart' for an interface to mean 'bring up the interface
as soon as the system boots', we are pretty much forced to go with
option (1).
All in all, option (1) seems more attractive, since it should save us from
dealing with a lot of low-level details of network setup, and the distro
scripts should be much better integrated with the rest of the system than
what we come up with for libvirt.
4. Misc issues
==============
* Should interfaces have labels/roles ('data-interface') to help admins
make sense of the current config ?
* Do we expect interfaces to be in a specific state before we create them
or do we just tear them down and reconfigure them no matter what ?
* Are there crucial config options that are not covered by the sketches
above (e.g., setting an explicit MTU) ? Are there things in the XML
sketches above that will be impossible to implement on some OS ?
* Should this even be done as part of libvirt ? It seems like a very
generic network config tool, and libvirt merely the conduit to exposing
this through an API, most importantly, a remotable API.

[libvirt] autostart with xend
by John Levon
It doesn't work quite right with a running domain. The 'new' will
correctly set the config, but the temporary config doesn't include the
new setting. So tests of the form "set autostart; is it set?" will fail.
Suggestions?
Also, why isn't this represented in the XML?
thanks,
john
