Hello,

I would like to know if the ressources of VM or LXC are dedicated of is it the max possible to use per service? (aka shared)

Thanks

What is a resource for you and what a service?

In terms of 'shared' for memory, there is KSM that combines identical memory pages, so they are technically shared between VMs. For the CPU, everything is shared, because all VM or LXC processes are real processes on the host, so ordinary scheduler is responsible for their cpu time. Disk is per default dedicated, e.g. for ZFS you can bind-mount them to other hosts so that is kind of shared.
 
Thanks for you reply, everything is clear now :)

BTW: by ressource I mean hardware ressource (cpu, ram), a service is a VM or LXC container
