Hi,
I'm trying to get NAT networking running as described in
http://libvirt.org/formatnetwork.html#examplesNAT
But in the guest, ifconfig shows only the lo interface. I created the kvm
image (debian lenny 5.0.3) directly with qemu-img and kvm, because virt-
install also didn't work. Afterwards I created the XML file for libvirt:
<domain type='kvm'>
<name>hadoop1</name>
<uuid>c40b6644-362a-e5ab-8825-cd1a7fbe24eb</uuid>
<memory>524288</memory>
<currentMemory>524288</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='x86_64' machine='pc'>hvm</type>
<boot dev='hd'/>
</os>
<features>
<acpi/>
<apic/>
<pae/>
</features>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/bin/kvm</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/hadoop1.qcow2'/>
<target dev='hda' bus='ide'/>
</disk>
<interface type='network'>
<mac address='52:54:00:05:74:bb'/>
<source network='default'/>
<model type='virtio'/>
</interface>
<!--serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target port='0'/>
</console-->
<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='-1' autoport='yes'
keymap='de-ch'/>
<video>
<model type='cirrus' vram='9216' heads='1'/>
</video>
</devices>
</domain>
The network config is:
<network>
<name>default</name>
<bridge name="virbr0" />
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<dhcp>
<range start="192.168.122.2" end="192.168.122.254" />
</dhcp>
</ip>
</network>
ifconfig of the host (needs cleanup, I know):
