Hello,
Hi,
Reading
https://www.ovirt.org/documentation/administration_guide/index.html#IPv6-...,
I see this tidbit:
- Dual-stack addressing, IPv4 *and* IPv6, is not supported
- Switching clusters from IPv4 to IPv6 is not supported.
If I'm understanding this correctly... does that mean I cannot run some
VMs with IPv4, and other VMs with IPv6, in the same cluster?
This applies mostly to host networking, there are cases when host
networking dual stack works fine, the issue is that it has many quirks.
oVirt cannot ensure that those quirks won't happen which might break your
connection.
In VM networks oVirt cares only for L2, with OVN it can also care for L3.
So configuration on your VM networks is up to you.
I can imagine that you could safely mix IPv4 and IPv6 for VM networks
without breaking any hosts, but I did not try that personally.
If so, that's incredibly disappointing and frustrating.
Is Dual-stack addressing a possible feature request?
You can fill RFE but I am afraid that it won't get far due to lack of
manpower.
IPv4 addresses are expensive... and I have a couple of customers who
only
needs IPv6, so would really prefer to avoid having to pay for IPv4
addresses for them.
