since a lot of things were added, and priorities usually change, I'd
like to ask again for "what do you need the most from oVirt / what are
your pain points" next?
I'd like to see some way to ensure redundant groups of VMs are running
on physically different hosts.
E.g. if I have 2 or 3 dns servers running in a VM, I'd like to have them
running on different hosts if they are available.
I'd like these VMs to "repel" each other w.r.t. the physical running
space. I imagine sometimes one could want the opposite as well, that two
VM's that depend on each other over the network are running as close
together as possible... (i.e. attract each other)
I'm sure this is all scriptable, but it seems to fit with the management
part of oVirt very well.
while scriptable, its been made an api in 3.3 (which allows to easily
extend the scheduler, until such features are incorporated into mainline
codebase as out of the box):
http://www.ovirt.org/Features/oVirt_scheduler
http://www.ovirt.org/Features/oVirtSchedulerAPI
its also going to be covered here tomorrow:
http://lists.ovirt.org/pipermail/users/2013-August/015936.html
(other than that - yes, above feature is positive/negative vm affinity
for scheduling and should be on the list)
