Re: [one-users] OpenNebula 4.2 - sunstone attach disk problem

I forgot to mention that volatile disks are created directly on the system DS. This might not be clear from sunstone. Were you referring to this when you asked if there is a way to change the default DS for volatile disks? Or were you thinking about the DS used to create new Images? Regards --

Hi Dmitri, I confirm Simon's statament that you can't do what you're suggesting due to OpenNebula's cache mechanism. However, we have recently found out scalability issues for large deployments, where the xmlrpc server is a bottleneck. In the next OpenNebula release we will provide configuration

Hi Simon, yes of course it will be available very soon. We're still working on it but you can expect that functionality to be there in the next release, or even the next maintenance release if there is one. Could you share your scalability experiences with us? Can you a be a bit more specific?

Hi Simon, If I understand correctly, by oned won't scale you mean that it's not currently possible to deploy multiple concurrent oned daemons and *not* that OpenNebula isn't able to handle very large deployments ( 10.000 vms). In my reply to Dmitri what I meant is that, once we provide a patch

Carlos, thank you. I ran some tests last night - used 'stress' on hosts to generate high CPU and Memory load. Impressive that ONE almost immediately detects real CPU/MEM usage on the host and won't deploy any VMs to the host. This is what I was looking for and it might work... Thanks.
