We have installed a MicroSoft Win7 system as a guest and have joined it
to our
MS AD domain. The system runs and has internet access. However, the IPv4 address it obtains and the gateway it is assigned are both sourced from
the
virtual machine host system and not from our AD DC DHCP server.
To clarify, the virbr0 IP address is 192.168.122.1 and the Windows guest
has
that address as its gateway and an IP address in the 192.168.122.0/24 netblock. This is not as we desire as the internal addresses we
regularly
assign to MS workstations via DHCP are supposed to belong to a different netblock entirely. This permit filtering on incoming and outgoing
traffic at
the gateway.
1. If I understand you correctly then you want to assign MS-Windows a IP which should not be from 192.168.122.0/24?
2. If that is yes then you have to configure your DHCP server so that machine which is a guest machine should get IP based on their MAC address. In VirtualBox MAC address is in this range 08:00:27:XX:XX:XX:XX, first three value will be constant for all guests.
I realize that there is a DHCP service running on virbr0 for the purpose
of
provisioning guests with system control traffic but I do not know how to
limit
that to its intended purpose and allow another DHCP server to provide
the IP
address to the windows guests. I hope that problem description is not
too
confusing.
Can anyone provide me with some guidance on the matter? Are kvm guests required to have either static ip addresses or dhcp addresses provided
by the
host system?
It sounds like what you need to do is create a bridge and then connect your virtual machine to the bridge so that it can receive DHCP from the external network. I assume you are using libvirt. If so, check out the page below. It may help you get started in the right direction.
