Hello all
The last months we have tested every well known visualization platform (ovirt, nebulla, cloudstack, openstack etc)
and probably we will stick with proxmox.
It is stable, easy to configure and to manage and almost bug free.
I have two questions
Are the resources that a VM can consume limited to the node resources?
IE i have a 4 node cluster. Each node has 1 CPU with 4 cores and 32GB ram and shared storage
Is there any way to assign all 4 CPUs from all nodes to one VM ? I mean, without load balancing etc
I have run some crash test to one VM, but i think that the VM was not even consuming the full CPU power from his own node.
All other nodes stay with 0% load average
So you can have many VMs in one node, but can you have one VM getting CPU and memory from many nodes?
And the second one
I have read the 2 proxmox books, the wiki, the forum but i still can not understand how the CPU power is shared in KVM visualization.
For example in esxi, one core is one core.
In proxmox, one core is something that only the kernel fair scheduler knows what to do with and hot to handle,
Can someone please explain this?
Thank in advance
