Is it possible to create a VLAN for WAN traffic, to separate it from the
internal network? I'd imagine so. It was a automated and simple process
when use XenServer. I'm trying to switch from Xen to oVirt and when trying
to recreate this, I'm unable to ping out from the VM.
This leads me to believe the VLAN was created incorrectly. I created
ifcfg-br1 on the host and through the engine, created the logical network
with VLAN tagging 20. Does the interface, ifcfg-br1, require a public IP,
any IP address, no ip address? (Sorry, never created a VLAN for WAN traffic
as it was automated in XenServer)
Assigning an IP-address to a VM network in oVirt is _not_ mandatory,
it is only needed for "management" networks (ovirtmgmnt, display, storage)
where the _hosts_ need connectivity to resources on that network.
Is this a tagged or an untagged vlan? (an untagged vlan means only one vlan
per physical interface andneeds no extra configuration on the OS side)
Which other (physical) interfaces are in your "br1" interface?
Are the (tagged) vlans assigned to this interface?
A vlan interface on linux looks like this: "eth0.20" where eth0 is the
"physical" interface on which tagged vlans are configured and 20 is the
number of one of those interfaces.
In the case of an oVirt VM network the physical interface is bridged (and
sometimes bonded)
so the interface configuration looks like this: "br1.20".
The "normal" route for configuring a new network in ovirt is to configure
it in the "networks" tab
(as a VM network) and then assigin this network to physical- or bonded
interfaces on all the
hosts in your cluster.
From there I have the VM installed and configured with a public IP
address, however, only get Destination Host Unreachable, meaning it has no
route out.
I am banging my head on the desk trying to figure this out. Can anyone
give me any assistance?
Thank you,
Neil
