What are Raw Disk Mappings?
In VMware you can create a Raw Disk Mapping to assign a physical hard drive directly to a virtual machine. This bypasses a VMFS datastore and allows you to dedicate a whole drive to a VM. One use for this would be to create a software RAID on a VM for a ESXi host that doesn’t have a supported RAID controller. Or if you are converting a physical machine to a virtual one and want to access the data without running VMware Converter. Continue reading Creating Raw Disk Mappings for VMware ESXi
Many of you may have wanted to run a Mac OS X virtual machine in your vSphere setup but get hit with the error that darwin11–64Guest is not supported, as outlined in VMware KB 2006093. As the KB explains that this is because you must be running Apple certified hardware to run a Mac OS X virtual machine. I’m sure that this has to do with the licensing of the OS X product. But you may want to run a vm or two to test software in your environment. Continue reading How to run a Mac OS X VM on non-Apple VMware ESXi host.
So, a few weeks ago I upgraded all my ESXi hypervisors in my lab to version 6.0. All was working perfectly but an older server started acting up. It is an ASUS RS500-E6/PS4 that was purchased back in 2012 that I have running with two Intel Xeon E5504 2.0GHz processors and 48GB of DDR3 memory. It has 2 x Intel 82574L Gigabit ethernet ports (keep that in mind). It ran fine on version 5.5 without a problem, but all of a sudden after the upgrade to 6.0 it began to exhibit the behavior when a decent network load was placed on it would drop connectivity to VMs then that would follow with the management interface dropping. After it happened I checked the DCUI and it was still up but all options were sluggish. Then after a few minutes the DCUI was completely unresponsive.
