What is ESXi really?

[hack3rcon]

Hello All.

Can you tell me what OS ESXi used? For example, Hyper-V use Windows OS and Citrix XenServer use Linux but how about Vmware ESXi? Is use BusyBox?

Thanks.

VMkernel is a POSIX-like operating system developed by VMware and provides certain functionality similar to that found in other operating systems, such as process creation and control, signals, file system, and process threads. It is designed specifically to support running multiple virtual machines and provides such core functionality as:

• Resource scheduling

• I/O stacks

• Device drivers

(POSIX - Portable Operating System Interface).

Other products like XenServer use Linux for dom0 but Vmware is not!!! I guess it is a big advantaged for Xen and Microsoft use Windows Core for Hyper-V too.

Is ESXi update free?

Cheers.

ESXi is architected differently from Xen or Hyper-V; it does not have a dom0 guest.

I never said it.

I said that Xen and Hyper-V use an OS core for performance and etc, But how about VMware?

[admin]

I suppose you could say that ESXi is an OS core.

Thus, ESXi is an OS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If yes, Is steal Linux features?

[admin]

ESXi is POSIX-like, as is Linux, so they do have some similarities.  However, ESXi does not share any code with Linux.
