Yes. Create a network definition, specify a host element to the dhcp
definition, attach the machine to the created bridge and it should work.
<network>
<name>sample</name>
<forward dev='eth0' mode='nat'/>
<bridge name='intbr0' stp='on' forwardDelay='0' />
<ip address='192.168.122.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.122.2' end='192.168.122.254' />
<host mac='AA:BB:CC:DD:EE:FF' ip='192.168.122.102'/>
</dhcp>
</ip>
</network>
Snippet for the domain definition:
<interface type='bridge'>
<mac address='AA:BB:CC:DD:EE:FF'/>
<source bridge='intbr0'/>
<target dev='vnet0'/>
</interface>

Is dnsmasq installed and running? Does the guest system use dhcp?
