HA with service monitoring inside VM

Hi everyone,

I have 2 proxmox nodes and I want to set up the high availability mode.
The question is how can i enable an automatic failover when a service is down inside the Virtual Machine.
For example when Apache service is down inside VM1 on Prox1 make it failover to VM2 on Prox2.
Is it possible? And what kind of configuration do I need?
Thanks for your help.

Regards
Eric
