We have a HP ML350G6 with VmWare ESXI4 on. When we try to install the os on a newly created VM, it's not possible to connect the host CD DRIVE of the server to my VM. We can install the OS using the VsPhere Client and than connecting the CD DRIVE of the pc to the VM. This is however a lot slower.
The CDDRIVE in the server is SATA connected.
