[one-users] Use computing resources of more than one node
Hello. A quick question: does opennebula support scaling a virtual machine to use the computing resources of more than a node at a time? Consider that one application uses 40 GB RAM, and we have 4 nodes with 16GB RAM each. Is this possible? Thank you in advance -- Sergiu B. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] problem with access to objects in opennebula 3.0
Hi, Why an user could access private objects from other users in the same group ? OpenNebula 3.0 documentation says opposite. http://opennebula.org/documentation:rel3.0:manage_users Regards, Rolandas P.S. I have images created with oneadmin and one of them public (published) and others - no. With regular user (in the group oneadmin) I can access all user oneadmin images (and create VM from them). The same was with the group users. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] Sharing workers between two front-ends
Hi, OpenNebula names the VMs, meaning the hypervisor instances, as one-id. You will probably have collisions. You can use this workaround: modify the pool_control table in the DB and set the last_oid for VMs to 1000 in one of the two front-ends. That will make one OpenNebula create VMs starting with one-1001, one-1002...

Re: [one-users] Use computing resources of more than one node
As fas as I know none of the hypervisors supported can do that. Even if they could share ram using the network this would make process execution staggering slow.

[one-users] Network configuration
Does OpenNebula contain networking support for assigning IP addresses OR is it something handled externally using a separate DHCP server? In my test install I was able to start a VM using existing DHCP server. But I did specify network configuration as mentioned here - http://opennebula.org/documentation:rel3.0:vgg . So do I really need NETWORK_SIZE, NETWORK_ADDRESS, and LEASE parameters? How does OpenNebula use them? jM ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
