Ok, this is it, there are many times when i need to find the path to certain configuration regardless of Proxmox or LXC or KVM or OpenVZ configuration file and i always need to 'remember' where it is and if you do this daily in and out, you might have an idea, if not, this is just another digging the web task! How about recording all these down for me instead? Hence, here are all the important path for anyone who needs it when dealing with Proxmox!
=== OpenVZ Section ===
config: /etc/vz/conf/xxx.conf
data: /var/lib/vz/root/xxx
template: /var/lib/vz/template/cache
snapshot: /var/lib/vz/dump
OpenVZ config: /etc/vz/vz.conf
=== KVM Section ===
config: /etc/pve/qemu-server/xxx.conf
data: /var/lib/vz/images/xxx
template: /var/lib/vz/template/iso
snapshot: /var/lib/vz/dump
=== LXC Section ===
config: /var/lib/lxc/xxx/config
data: /var/lib/vz/images/xxx
template: /var/lib/vz/template/cache
snapshot: /var/lib/vz/dump
=== Cluster Section ===
config: /etc/pve/cluster.conf
nodes vm config: /etc/pve/nodes/xxx/xxx/qemu-server/xxx.conf
=== Files ===
corosync.conf => corosync/cman cluster configuration file (previous to PVE 4.x this file was called cluster.conf)
storage.cfg => PVE storage configuration
user.cfg => PVE access control configuration (users/groups/...)

nodes/${NAME}/priv/pve-ssl.key => private ssl key
nodes/${NAME}/qemu-server/${VMID}.conf => VM configuration data for KVM VMs
nodes/${NAME}/openvz/${VMID}.conf => VM configuratin data for OpenVZ containers
=== Symbolic links ===
local => nodes/${LOCALNAME}
qemu-server => nodes/${LOCALNAME}/qemu-server/
openvz => nodes/${LOCALNAME}/openvz/
=== Special status files for debugging (JSON) ===
.version => file versions (to detect file modifications)
.members => Info about cluster members
.vmlist => List of all VMs
.clusterlog => Cluster log (last 50 entries)
.rrd => RRD data (most recent entries)
=== Enable/Disable debugging ====
