my point wasn’t to compare the two – my point was that it’s possible to boot one OS and load a completely different one, and have no architectural relationship between the booted OS and the running one.

someonewhoreallyknows: Linux and DOS are not the same beast. Come on, DOS didn’t even have memory management…

Glandium –

there’s a long history of booting a basic operating system to load a more sophisticated one. I may be dating myself, but Netware 3.X/4.x would boot DOS, and then load the netware kernel. That didn’t mean that netware was based on DOS. In fact, there was even a command that would remove DOS from memory after netware was started.

The VMKernel is NOT based on Linux, no matter what the service console may look like.

rob: considering the vmkernel is started by an init script on the service console, and that what grub starts is the service console linux kernel…

Glandium – you suffer fromm a common mis conception – the VMkernel boots the ESX server – the system console is infact a special virtual machine brought up after VMkernel bot time.

VMkernel is not based upon linux, nor does it run on top of linux – in fact the complete opposite is true.

You’re both half right. The vmkernel runs on top of the linux kernel of the service console.

John’s right. ESX Server runs on the bare metal. -ian

That’s actually not true. Although the service console, which manages interaction with the VMkernel, is built on Red Hat, the actual VMkernel hypervisor is not based on Linux.
