I just discovered proxmox and find it to be fanstastic!! I have been using other virtualization software like vmware, virtualbox and so on. However, what attracted me to proxmox is the clustering feature out of the box. Really neat feature and important one too considering everyone talking about cloud computing nowadays.
Anyway, I have some really noob questions about clustering in proxmox which I can't find the answer to.
1) I read in docs about getting the hardware for clustering to be as equal as possible. Why is that? Doesn't the virtual environment create the same type of 'hardware' in the eyes of the VMs? We can't possible do that when let's say we add a new server into the cluster 2 years later.
2) what about the proxmox version? Must they all be the same? Again, let's say we add another server 2 years later when there are already new version out. This leads to question 3.
3) how easy it is to upgrade proxmox especially when they are running in clusters?
4) do we need to pay for using cluster?
5) is it hard to setup vm failover in cluster? Or even possible?
