[Openstack] Can't restart devstack.

Hi, all. Trying to get a feel for OpenStack, so I installed DevStack. And it works great... until I have the audacity to restart it. Apache doesn't go fully live unless I do a restart -- and if I do that, I don't get past the login screen (just tells me that admin had trouble authenticating)

[Openstack] Missing "allowed address pairs"?

Hi, all. I've got two instances -- a Juno and an Icehouse -- both set up via Ubuntu/Juju. And neither of them shows "allowed address pairs" when I do a "neutron ext-list" (I've tried on both the neutron-gateway and nova-cloud-controller). From everything my co-worker and I have read, it seem

Hey, all. I've got an Openstack install, with each control node on its own 24 GB, quad-core system. And yet my Horizon is really quite slow; I've seen it take 15+ seconds to log in, click on the "routers" tab, etc. The only host among the control nodes that showed significant pain was the M

Trying to get a good idea of how they work. As I get it, host aggregates are collections of (not necessarily mutually exclusive) hosts that share a metadata value. And they can be part of availability zones which can be (say) specific to networking hardware, or CPU, or something. What I'm tr

Hey, all. Trying to have geographically-dispersed legs to a ~60 node liberty development cloud. Based on the traffic I see back and forth on our icehouse cloud, it makes me think that having a cell hierarchy for the new cloud might cut down on the back-and-forth chatter -- which would be good

So, I've got an Icehouse cloud that had been working fine; then we had to bring everything down for an extended power outage, and stuff still isn't quite right. The nutshell problem is that only one of my two neutron gateways seems to be able to route to the metadata server. The "working" neu

[Openstack] Migrating images off compute node?

Re: [Openstack] Horizon console WAY slow for an instance

My rule-of-thumb for stuff that falls into the "really slow but works" camp is, check DNS. If possible, disable reverse lookups, or else ensure that the hosts involved all know how to reverse-resolve each other's IP addresses. That's where I'd start, anyway. Good luck! -Ken On 2016-06-28 2
