Make sure Intel No-Execute (XD) is enabled It's also possible a BIOS update can help make sure the compatible version of Streaming SIMD Extensions (SSE) for both hosts.

The following best practice prevents this problem from occurring: Always unmark devices for passthrough before removing them from the server. The following workaround describes how to force the change from passthrough mode to non-passthrough mode: Edit the /etc/vmware/esx.conf file by changing the owner of the PCI device from passthru to vmkernel. The ...

Using the Vsphere Client select your host, then the Configuration tab, select Advanced Settings in the Hardware section, then Configure Passthrough and de-select the PCI device you're concerned about and reboot the host.

would using the same virtual network device improve network performance? VMXNET3 is, with up to date vmtools installed, easily the most efficient method to use, it should reduce your hosts CPU load but won't actually lower the amount of traffic your VMs are sending, in fact it may increase it as it's more efficient. Sounds like your switch is out of ...

There's no good reason NOT to use a standard Hyper-V or VMware ESXi setup for this simple use case. What is wrong with those industry-leading options? It's strange to ask for "free, open source, Windows compatible, enterprise-ready, and secure" and ignore the two largest players in the market. The VMware ESXi hypervisor is FREE. But paid variants start ...

See: http://www.yellow-bricks.com/2012/02/08/distributed-vswitches-and-vcenter-outage-whats-the-deal/ Network connectivity during a vCenter outage is preserved. The ability to modify the vDS settings is impaired, but the VMs will maintain connectivity.

It could be safe It depends on your security requirements and level of risk you are willing to take. Here are some considerations/ideas SSH is fairly secure, especially when forcing key authentication. Networks provide remote access via VPNs all the time. SSH is not much different. Password encrypt your SSH keys Enable automatic security updates You ...

Running Fiddler when PowerCLI was going, I saw that https://servername/sdk is in fact the location of the API. I took the wsdl files provided in the vSphere SDK download and hosted them locally. Then I was able to generate a SOAP client based on them, and then I pointed the client's endpoint to the actual service.

I am not sure why you have not tried using PowerCLI, that would be the easiest and fastest way to do that. You can change the network adapter from connected to disconnected, change the network label (vLAN), or remove it all together. From all the times I have used this I have not come across any adverse effects on the VM's.
