<pre wrap="">Thanks Olivier, for your suggestion.
For experimentation, I simply added the following line into the VM template:
NIC=[ MAC="00:02:01:23:45:67" ]
But I have been getting permission denied errors.

I have tried changing the group for /dev/net/tun to "cloud", which
corresponds to the group value in /etc/libvirt/qemu.conf. I've also
tried modifying /etc/libvirt/qemu.conf for the cgroup_device_acl field
as follows.
cgroup_device_acl = [
"/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc", "/dev/hpet",
"/dev/net/tun",
]
What else could be wrong? Thanks.</pre>

<pre wrap="">Hi,
I am trying to setup OpenNebula for our research work.
For now, we have one machine with a single NIC to experiment with. How
can one configure a guest to use DHCP for getting an IP address? I
know one can specify leases (as described here
<a class="moz-txt-link-freetext" href="http://opennebula.org/documentation:archives:rel3.0:vgg">http://opennebula.org/documentation:archives:rel3.0:vgg</a>) in the
virtual network template file. However, we do not have access to the
DHCP server, thus it is not possible for us to specify the IPs.
The solutions suggested here
(<a class="moz-txt-link-freetext" href="http://lists.opennebula.org/pipermail/users-opennebula.org/2010-November/003349.html">http://lists.opennebula.org/pipermail/users-opennebula.org/2010-November/003349.html</a>)
involves setting up a virtual DHCP server or knowing in advance the IP
ranges. But are there any ways to request IPs from the existing DHCP
server directly?
</pre>

<pre wrap="">You can configure a network in OpenNebula that defines only MAC
addresses (range of virtual ones).
Then, all you need is to have images with network config configured for
DHCP. Your DHCP will answer to the request.
This is not a requirement that OpenNebula manage the IPs, this is only a
feature.
