you could try sending text-only emails :)
By the 'ovirt hypervisor packages' I meant installing the OS first of
all and then making it into an ovirt 'node' by installing the required
packages, rather than installing from a clean slate with the ovirt
node iso. Sorry if that was a bit unclear.
Okay - thanks for the explanation.
In general I would discourage from installing the ovirt-node package ona
normal host.
If you still want to try it be aware that the ovirt-node pkg might mess
with your system.
I'm pretty sure we are on the same page here. I just checked the ovirt
'quickstart' page and it calls the various hypervisor nodes 'hosts'.
ie: Fedora host, EL, host, ovirt node host.
If the ovirt node included the qemu-kvm-rhev package - or an updated qemu-kvm
- it would mean that both ovirt node hosts and fedora hosts could both
support live storage migration. It would only be EL hosts that do not
support that feature at this stage. We could have a caveat in the
documentation for this perhaps.
Fabian, were you think thinking that if not all 'hosts' supported live
migration that the cluster could disable that feature? Based on capabilities
that the hosts would expose to the ovirt server? This would be another way
of avoiding the confusion.
Thanks guys for the great work you are doing with ovirt.
Paul,
this is something that vdsm needs to report to the engine, so the engine will
know what is / isn't supported. It's a bigger request as today we're mostly
based on cluster compatibility level.
Additionally it is possible to mix .el hosts with nodes with old (non -rhev)
nodes.
Each of these cases will break live-storage migration.
How do you suggest to mitigate it?
seems like another case of feature level negotiatio.
