Re: [Xen-users] Hardware virtualization

[Luisa Posani <lposani@xxxxxxxx>]

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).

Sure, I can.

You should check your cpuinfo if it supports virtualization. Look here http://virt-tools.org/learning/check-hardware-virt/

If it does, tell me what is your goal and what have you done already?

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.
