Hi all,
I'm installing oVirt for the first time and I'm having some issues
with the Networking.
Setup:
OS: CentOS 7 Mininal
3 Bare Metal Servers(1 for Engine, 2 for Nodes).
Network:
Nn Trunk Interfaces with VLANs and Bridges.
e.g.:
trunk.100, VLAN: 100, Bridge: vmbr100. IPV4 only.
I have already a VLAN for MGMNT, without DHCP Server(not needed for
oVirt, but explaining my setup).
Networking works as expected, I can ping/ssh each host without
problems.
On the two nodes, I have a Interface named ovirtmgmt and dhcp...
Question 1: What kind of configuration can I use here? Can I set
static IPs from VLAN MGMNT and put everything from oVirt on that
VLAN?
Yes.
oVirt doens't have a Internal DHCP Server for Nodes, or?
oVirt doens't have an internal DHCP Server.
Question 2: Should I leave oVirt to Setup it(ovirtmgmt Interface)
for
me?
I would use the comfort oVirt provides to configure the hosts, if there
is not a good reason to take the burden on me.
Problems:
I configured the Engine with the IP 1.1.1.1, and I reach the web
interface with https://FQDN( which is IP: 1.1.1.1)
But, when I add a Host to the Cluster, I have some errors:
"Host XXXX does not comply with the cluster Default networks, the
following networks are missing on host: 'ovirtmgmt'"
Try to use the "Setup Host Networks" functionality of oVirt.
If you select a host in the Administration Portal, there is
a tab labeled "Network Interfaces", which provides a button "Setup Host
Networks".
In the "Setup Host Networks" dialog is a graphical representation of
all logical networks, which can be assigned by drag'n drop to the
network interfaces of the host.
Question 3: I saw that Engine tries to call dhclient and Setup an IP
for it, but could I have static IPs? Where can I configure it?
In the "Setup Host Networks" dialog each assigned logical network has an
icon of a pencil, which can be used to open an other dialog to
configure IP addresses.
