[opensuse] Virtualization in reverse
I come from a mainframe background where the virtualization platform was THE main OS. Why can't VB or VMWare be designed to be booted first - just like the mainframe - that way, there is only ONE main OS to code for (itself).

Xen virtualization does exactly that. (Although it is whole a lot more complicated to manage it then VirtualBox or VMware. -- Regards, Rajko. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

VMware is. It's called ESX Server (or ESXi). As to why the standard products aren't designed that way, you'd probably have to ask them, rather than a group of openSUSE users. ;) Jim -- Jim Henderson Please keep on-topic replies on the list so everyone benefits -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

To clarify - yes, ESXi uses a Linux kernel as its basis - at some point, you have to have I/O and device interfaces, and using the Linux kernel provides that functionality without having to recreate everything (device interfaces/drivers/etc) from scratch. But doing so that way (or not) is a design decision. As Rajko pointed out, Xen does this (as does KVM as I understand it) as well.

VM of course.

That's pretty much how xen works. You boot the hypervisor first, then the guests. -- Per Jessen, Zürich (-2.5°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It can, and I believe it has. I am pretty sure that vmware is working with one or more server vendor to provide a vmware hypervisor directly in the hardware(firmware). I can't find a link about it now, but I remember reading about it a couple of years ago Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Vmware has a bare-metal version but its expensive. See ESX. I asked them why there wasn't a bare metal version of Vmware Workstation, and he told me he gets at least one request a week for that product, and he wishes he could sell it, but corporate whon't let them put it on the market because it would murder his ESX sales. The implication was clear from the conversation that they have this in-house. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

ESXi is a 'lite' version of the full ESX product. It's available for free, but has some limitations compared to the full product (mostly around number of CPUs or amount of memory IIRC).

Still looks pretty useable especially for someone currently using Workstation. Workstation has some limitations on sizes and stuff too. I think I'll scratch around for a box that meets the specs and try it out. It would be nice to not have to worry about the underlying OS. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

A year or two ago, ESX requited a SCSI controller. They did not have any SATA controller drivers in it. I don't know about now,.nor do I know about ESXi. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Oh, yes, it is very usable. I did some contract work where ESXi was used as a development cloud (the product in question supports ESX and ESXi along with most other hypervisors) and it's definitely very useable.
