Re: [Xen-users] Hardware virtualization
Hi Luisa,
great news, i use Remmina also. Great tool.
'disk = ' is used for defining VM's hard drive. I'm not familiar
with buildroot but as I read about CPIO it's file archiver and Xen
disk image should be in RAW format. So you should extract
rootfs.cpio to raw disk image which could be created with dd.
Example:
dd if=/dev/zero of=rootfs.img bs=1M count=10000
As with normal hard drive you can use fdisk make some partitions on
rootfs.img, format them and extract rootfs.cpio there. Then you can
set this harddrive img in your xen config file for HVM style (hda
but it should apper as sda inside domU):
disk = [ 'file:/path/to/rootfs.img,hda,w' ]
Or you can pass the path to rootfs.img to xen-create-image. If
rootfs.cpio contains all files including kernel image it should boot
normally. As I wrote I'm not familiar with buildroot thus you're
little bit on your own in this case and i'm sorry for not being more
straightforward but you're using specific scenario. Maybe I'll save
some time for testing this and let you know later on.
Have a nice day

Hi Jan
I launch my windows VM whit graphical program named
"Remmina Remote desktop client" and it work well..
:-) :-) :-) :-)
Maybe
I was wrong a few parameters to launch manual
gncviewer
Let
me explain what is my
main problem.
I would like to start a virtual machine created with
buildroot standard
WHITOUT XEN drivers in the VM.
I have some problems
creating the configuration
file for this virtual machine.
I don't know if
I have to work with a
ramdisk
(rootfs.cpio
created by
buildroot) or not and
what should be the
configuration file under
(p.e.) /etc/xen/VM_buildroot.
I
don't understand the meaning
of the 'disk =' in the configuration file.
you know a
tutorial that I could
follow to create this file?
Xen provides the
xen-create-image command
to create the file, but I do
not know how to give
parameters to the command (initrd install-install-source method ...)
Can
you help me?
Thanks in advance.
Luisa

Hi Luisa,
great, so you're cpu is capable for running Xen. The
reason why you don't see it is explained here http://old-list-archives.xen.org/archives/html/xen-users/2010-09/msg00180.html.
Just to be clear. You've already start your system
with xen and tried to start Windows Xp domU as this
guide describes, do you? And the problem is that you
can't connect to your Windows XP domU with GNCVIEWER
or something else? Is your domU running? What does
the "xl start" command say?
Thank you and have a nice day

Hi
if I make
/proc/cpuinfo flags
without xen I found vmx.
when I start PC with xen flag vmx doesn't
appare.
Why?
I would like use a guest OS make with
buildroot "standard" without xen driver.
I use http://wiki.xen.org/wiki/Xen_Beginners_Guide#Configure_GRUB_to_start_Xen
but doesn't work correctly.
Doesn't work gvncviewer for using a window
XP iso image and now I'm compiling a
buildroot standard (qemu_x86 config).

Thank's for
your indication.
I can't find my cpu in
your list.
In my PC I can enable the
virtualization from BIOS.
I don't understand the
difference.
Can you help me please?

Hello Luisa,
here http://en.wikipedia.org/wiki/List_of_IOMMU-supporting_hardware
is a list IOMMU
supporting hardware,
this is a good point
to start. IOMMU is
not necessary for
virtualization, but
hardware listed here
supports VM.
