Summary:
When an ESX/ESXi host fails for any reason, all the running hosted VM instances also fail. Practical Redundancy between two guest machines ( virtual instances) is possible, only if the two ESXi host machines are redundant as well.
Symptoms:
To achieve practical redundancy and configure High Availability between two ESXi Virtual Machines. For more information, refer to the following link:

Cause:

Solution:

Junos Space nodes, when running on the same ESXi host Virtual machine, can become part of the Fabric, but practical redundancy cannot be achieved in such a situation.

If the whole Virtual Machine ESXi server goes down, neither of the nodes can become active. Clustered Junos Space nodes are required to be a part of different ESXi hosts and most importantly, these ESXi host machines must have redundancy as well.
