We have a server with VMWare ESX4.1 installed on it. The physical machines has 2 quad-core CPUs and 16GB memory. We already have up and running 2 VMs, each configured with 2 CPUs (=2 cores) and 8GB of RAM. We have RadHat 5.5 installed on them. We are now configuring 2 additional VMs with similar configurations.
The problem is that after installing the servers with the RedHat Linux OS, they won't start at all. As if there is no OS on the VM. At the 3rd attempt (of re-install) one VM started without a problem.
Does anyone have a similar experience? Is this a bug in ESX4.1 or some other problem? Is there a way to prevent this from happening?
