sometimes the vSphere Client does not determine when an underlying Volume is expanded. So you cannot expand the datastore by the WebGUI or vSphere Client.
But the command line way is still possible 🙂 These are the steps:
in some circumstances a Windows guest VM does not boot and stops with Error:
- Stoperror: 0xc000186
- Boot critical file C:\windows\system32\ntoskrnl.exe is corrupt.
ESXi: Cannot start VM. Invalid MAC address specified. 12:34:6:78:90:12 is not an allowed static Ethernet address
VMware vSphere does only allow to set MAC Addresses from the Range 00:50:56:00:00:00 up to 00:50:56:3f:ff:ff. You can set a static MAC out of this range but cannot start the virtual machine. The typical error message is:
Invalid MAC address specified. 12:34:6:78:90:12 is not an allowed static Ethernet address. It conflicts with VMware reserved MACs.
