I have a shared network called “Admin" where I run my admin services like
logstash, Nagios, collectd, remote syslog server etc.

L3 routes are also in place to ensure that Vms on the Public subnet can
reach the admin VMs on the shared Admin network.

All VMs are configured to push data to the log server, mon servers etc.

As long as you have routes in place (and proper firewall rules to allow traffic),
you would be able to push your logs from guest VMs (or physical hosts like
hypervisors) to the designated log collection server(s)
