Re: [Xen-users] Hardware virtualization
Try set your domU memory to 512M with:
memory = 512
You should set:
dom0_mem=512M
in your grub command line and reboot also to prevent Dom0 from
ballooning.

Seems like you don't have enough mem
for your domU. How much memory do you have
on your dom0 / xen host?

I Jan.
I try to use a old rootfs.img
taht work well with qemu.
The configuration file contains:
kernel =
"/usr/lib/xen-4.0/boot/hvmloader"
builder='hvm'
memory = 1024
vcpus=2
vif = ['bridge=xenbr0']
disk = ['file:/home/posani/nine_disk_1.img,hda,w',]
acpi = 1
device_model = 'qemu-dm'
boot="d"
sdl=0
serial='pty'
vnc=1
vnclisten=""
vncpasswd=""
name="stefano"
but I have the error:
xm create /etc/xen/prova -c
Using config file
"/etc/xen/prova".
Error: I need 1062912 KiB, but
dom0_min_mem is 200704 and
shrinking to 200704 KiB would
leave only 793340 KiB free.
Where is the problem?
Help me....

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

Why?
I would like

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.
