[ovirt-users] Re: New oVirt setup with OVN : Hypervisor with LACP bond : queries
Can you give some more details about your current vSphere
infrastructure?
What about the level of downtime you could give when migrating?
Have you already planned the strategy to transfer your VMs from vSphere to
oVirt?
We are still in the initial stages and so conducting a POC.
Take care that probably on your VMware side your VMs have virtual hw
for
nics defined as vmxnet, so when you migrate to oVirt, it will change and so
depending on your OS type (Windows based or Linux based) and in case of
Linux, depending on your distro and version, some manual operations could
be required to remap vnic assignments and definitions.
We are planning to clone a VM and then migrate it to note down the findings. We will
surely verify the virtual nic hw as well.
Take care that in RHV this feature is still considered Technology
Preview,
so not recommended for production. It could apply to oVirt even more, so...
BTW, what do you mean with "... the fact that we have a SDN..."? Do you
mean standard virtual networking in contrast with physical one or do you
have any kind of special networking in vSphere now (NSX or such...)?
We have SDN implemented at our physical network level. IIRC it is Cumulus. We do not have
NSX. What I meant was as we have SDN implemented at the physical network level. So will it
make it easier to connect our Ovirt to the physical network.
I will go through the docs you updated and come back.
That was a thread originated by me... ;-)
But please consider that it is 5 years old now! At that time we were at 4.1
stage, while now we are at very different 4.4, so refer in case to recent
threads and better recent upstream (oVirt) and downstream (RHV) official
documentation pointed above
Also, at that time ansible was not very much in place, while now in many
configuration tasks it is deeply involved.
The main concern in that thread was the impact of having OVN tunneling on
the ovirtmgmt management network, that is the default choice when you
configure OVN, in contrast with creating a dedicated network for it.
My apologies. I wasn't clear. As the IP was assigned on bond0 which is a LACP bond, do
we need to make any changes before running the vdsm-tool ovn-config <ovn-central-ip>
<hypervisor ip> ?
some manual undocumented steps through OpenStack Networking API or
Ansible
could be required depending on your needs
I'll go through the docs you mentioned and update here about my progress.
