By design, all VMware virtual machines are isolated from one another. vSphere HA advanced options. Other PCs in the network can work with the guest, only the host can't do it. BUT if you have a fully redundant network infrastructure like the most of that I have seen than there is not a "real" chance for a isolation (except the host or FDM service crashes) or partition within this site. As part of disconnecting a host, vCenter Server disables HA on that host. If there is a known issue in the nested hypervisor, your host still is unaffected, as a breakout would need to go two layers of different OS/types. Every time we tried to create a new virtual machine it only offered 32-bit OS’s instead of 64-bit even though my processor is 64-bit. Various checks are performed to detect these failures. If a host does not receive any heartbeats from other hosts anymore and also cannot each the isolation address it triggers isolation response. Whereas if you have a secondary service console on a seperate vlan, you'd have to have issues on both vlans in this scenario before host isolation.
