[one-users] iSCSI Storage
Dear all, i was looking for information on how to include iSCSI storage into an opennebula cluster, the question is, whether i can mount iSCSI volumes directly on the frontend and on the cluster nodes ? Or do i have to mount it on the frontend node and export it to the cluster nodes ? I am sorry if this is in the documentation, but i did not find a definite answer Regards Soeren ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] shutting down VM vs stopping it
Hi! Tino has already explained the difference between deleting and shutting down VM in [1]. But I wonder what the difference is between shutting down VM and stopping it (I mean 'onevm shutdown' and 'onevm stop'). It's not clear from onevm man page [2]. Thanks. Nikolay.

Re: [one-users] cpu overcommit with kvm
Hi I already tried CPU setting, but the guest will see half of the real frequency of my host CPU: this isn't cpu overcommit, I am just saying to allocate half of my 8 cpu to that VM (or not?). No, the host will see the same CPU speed. The CPU attribute in the template is only for OpenNebula and the scheduler. What I am trying to achieve is what I already do with other KVM-based virtualization platforms: Using CPU and VCPU you can achieve this, the goal of CPU is to guide the host overcommitment.
