[MUST WATCH YOUTUBE VIDEO] [SUCCESS REPORT] Xen VGA Passthrough to Windows 8 Consumer Preview HVM Virtual Machine with Xen 4.2-unstable Changeset 25070 and Linux Kernel 3.3.0 in Ubuntu 11.10 amd64 dom0

[Teo En Ming (Zhang Enming)]

Dear Xen Users and David Techer,

It is only in the last few days that I have had great success with Xen
VGA Passthrough to Windows 8 Consumer Preview HVM Virtual Machine with
Xen 4.2-unstable Changeset 25070 and Linux Kernel 3.3.0 in Ubuntu 11.10
amd64 dom0.

Please do watch my Youtube video on successful Xen VGA Passthrough to
Windows 8 Consumer Preview HVM domU.

Youtube video link: http://www.youtube.com/watch?v=kGH05ZoMk6o

The duration of my home made video is only 26 minutes. My Youtube video
demonstrates Xen VGA Passthrough of my Palit NVIDIA Geforce 8400 GS PCI
Express x16 to Windows 8 Consumer Preview HVM.

Also read the documentation I have written for Xen, Linux Kernel and Xen
VGA Passthrough.

Ubuntu and Debian Linux
Version: 1.3

*dons moderator hat*

Please stop sending unsolicited mail such as this to this list.

I'm not suggesting this material is somehow useless, but this
is a technical support mailing list and not a blog, so we'd quite like
to keep the traffic concentrated on solving known problems for people
asking about them.

It would be very useful if you could put this material up on a blog
somewhere, though. There's a good many means of hosting a blog for free
on the Internet and I'm sure people here would be able to provide
reccomendations if needed.

Thanks!

> Dear Xen Users and David Techer,

Isnt xen dead yet? When will you start creating videos about qemu-kvm, the
officially supported VM?

[Teo En Ming (Zhang Enming)]

Dear compdoc,

Xen virtualization is still very much alive! As a matter of fact, Linux
Kernel 3.x officially supports Xen Dom0 and DomU.

I will not be using Linux KVM so there won't be a Youtube video for it.

Thank you very much.

Yours sincerely,

Teo En Ming (Zhang Enming)

Personally, I find VirtualBox a great deal easier - but then my CPU

doesn't have H/W VT so I can't use Xen or KVM.

Not to be a pedant, but you can use XEN without H/W VT, you just can't do certain things.

True and a good point. But what it can do without H/W VT is no use to me. :¬)

Once upon a time, I'd probably have tried it just for curiosity's
sake, but these days, now I have a 64-bit PC with 4GB of RAM, I have
played extensively with virtualization & I'm not curious any more.

They do the same thing for some definitions of 'same', but not yours :)

While KVM *is* a kernel module that essentially makes the Linux kernel
into a hypervisor, Xen is a layer that sits below the kernel.

When you install Xen onto a Linux machine, that machine becomes a guest
of the Xen host; it becomes the dom0, which is an especially privileged
guest, but it is still running atop Xen and the Linux kernel no longer
has direct access to the hardware.

Oh really? Nice explanation. I did not realise that. So it is, in
essence, doing much the same as VMware ESX, then?

How does the boot sequence work? Does Xen load first, before the kernel?
