support a variety of options:</p><ol><li>Userspace SLIRP stack
|
||||
<p>Provides a virtual LAN with NAT to the outside world. The virtual
|
||||
network has DHCP & DNS services and will give the guest VM addresses
|
||||
starting from <code>10.0.2.15</code>. The default router will be
|
||||
<code>10.0.2.2</code> and the DNS server will be <code>10.0.2.3</code>.
|
||||
This networking is the only option for unprivileged users who need their
|
||||
VMs to have outgoing access. Example configs are:</p>
|
||||
<pre><interface type='user'/></pre>
|
||||
<pre>
|
||||
<interface type='user'>
|
||||
<mac address="11:22:33:44:55:66:/>
|
||||
</interface>
|
||||
</pre>
|
||||
</li>
|
||||
<li>Virtual network
|
||||
<p>Provides a virtual network using a bridge device in the host.
|
||||
Depending on the virtual network configuration, the network may be
|
||||
totally isolated,NAT'ing to aan explicit network device, or NAT'ing to
|
||||
the default route. DHCP and DNS are provided on the virtual network in
|
||||
all cases and the IP range can be determined by examining the virtual
|
||||
network config with '<code>virsh net-dumpxml <network
|
||||
name></code>'. There is one virtual network called'default' setup out
|
||||
of the box which does NAT'ing to the default route and has an IP range of
|
||||
<code>192.168.22.0/255.255.255.0</code>. Each guest will have an
|
||||
associated tun device created with a name of vnetN, which can also be
|
||||
overriden with the <target> element. Example configs are:</p>
|
||||
<pre><interface type='network'>
|
||||
<source network='default'/>
|
||||
</interface>
|
||||
|
||||
<interface type='network'>
|
||||
<source network='default'/>
|
||||
<target dev='vnet7'/>
|
||||

|
||||
</interface>
|
||||
</pre>
|
||||
</li>
|
||||
<li>Bridge to to LAN
|
||||
<p>Provides a bridge from the VM directly onto the LAN. This assumes
|
||||
there is a bridge device on the host which has one or more of the hosts
|
||||
physical NICs enslaved. The guest VM will have an associated tun device
|
||||
created with a name of vnetN, which can also be overriden with the
|
||||
<target> element. The tun device will be enslaved to the bridge.
|
||||
The IP range / network configuration is whatever is used on the LAN. This
|
||||
provides the guest VM full incoming & outgoing net access just like a
|
||||
physical machine. Examples include:</p>
|
||||
<pre><interface type='bridge'>
|
||||
<source dev='br0'/>
|

|
||||
</interface></pre>
|
||||
</li>
|
||||
<li>Generic connection to LAN
|
||||
<p>Provides a means for the administrator to execute an arbitrary script
|
||||
to connect the guest's network to the LAN. The guest will have a tun
|
||||
device created with a name of vnetN, which can also be overriden with the
|
||||
<target> element. After creating the tun device a shell script will
|
||||
be run which is expected to do whatever host network integration is
|
||||
required. By default this script is called /etc/qemu-ifup but can be
|
||||
overriden.</p>
|
||||
<pre><interface type='ethernet'/>
|
||||
|
||||
<interface type='ethernet'>
|
||||
<target dev='vnet7'/>
|
||||
<script path='/etc/qemu-ifup-mynet'/>
|
||||
</interface></pre>
|
||||
</li>
|
||||
<li>Multicast tunnel
|
||||
<p>A multicast group is setup to represent a virtual network. Any VMs
|
||||
whose network devices are in the same multicast group can talk to each
|
||||
other even across hosts. This mode is also available to unprivileged
|
||||
users. There is no default DNS or DHCP support and no outgoing network
|
||||
access. To provide outgoing network access, one of the VMs should have a
|
||||
2nd NIC which is connected to one of the first 4 network types and do the
|
||||
appropriate routing. The multicast protocol is compatible with that used
|
||||
by user mode linux guests too. The source address used must be from the
|
||||
multicast address block.</p>
|
||||
<pre><interface type='mcast'>
|
||||
<source address='230.0.0.1' port='5558'/>
|
||||
</interface></pre>
|
||||
</li>
|
||||
<li>TCP tunnel
|
||||
<p>A TCP client/server architecture provides a virtual network. One VM
|
||||
provides the server end of the netowrk, all other VMS are configured as
|
||||
clients. All network traffic is routed between the VMs via the server.
|
||||
This mode is also available to unprivileged users. There is no default
|
||||
DNS or DHCP support and no outgoing network access. To provide outgoing
|
||||
network access, one of the VMs should have a 2nd NIC which is connected
|
||||
to one of the first 4 network types and do the appropriate routing.</p>

capabilities of the host and virtualization engine to which
