Where are the virtual disk images stored

Hello Everyone,

I am currently working on a project where I need to know the location of
the Virtual Disk Images on my server.
My server runs on a Debian Squeeze (v.6) Linux Distribution and uses Xen
v2.6.32. I have created a VM called VM4LiveFS and when I execute the cat
command on its cfg file (located in /etc/xen) I get the following:

#
# Configuration file for the Xen instance VM4LiveFS, created
# by xen-tools 4.2 on Wed May 15 14:49:19 2013.
#

#
#  Kernel + memory size
#
kernel      = ''/boot/vmlinuz-2.6.32-5-xen-amd64''
ramdisk     = ''/boot/initrd.img-2.6.32-5-xen-amd64''

vcpus       = ''1''
memory      = ''2048''

#
#  Disk device(s).
#
root        = ''/dev/xvda2 ro''
disk        = [
                 
''file:/vmstore//domains/VM4LiveFS/disk.img,xvda2,w'',
                 
''file:/vmstore//domains/VM4LiveFS/swap.img,xvda1,w'',
              ]


#
#  Physical volumes
#


#
#  Hostname
#
name        = ''VM4LiveFS''

#
#  Networking
#
vif         = [ ''ip=88.197.53.126,mac=00:16:3E:5E:E6:9E'' ]

#
#  Behaviour
#
on_poweroff = ''destroy''
on_reboot   = ''restart''
on_crash    = ''restart''

I need to know where are the disk images in my host''s filesystem. Any
hints
to where they might be..?

Thank you

Have you checked these paths?

Did you read the created config file?

Just to be clear, there''s no /vmstore/domains/VM4LiveFS directory? If
you''re able to use the VM you said you created then this path should be
there.

Re: Where are the virtual disk images stored

Ohh, I see what I did not check until now..

I thought the file:/ prefix was some other path and now I realized that the
vmstore is located in the root / directory.
I have just found it and the VM4LiveFS is there. Thank you for your help
and your time.

(Yes, I will do it. I am sorry for not doing it).

Thank you for your time.

Sincerely,
Nick

You wrote it still here:
>disk        = [
>                 
''file:/vmstore//domains/VM4LiveFS/disk.img,xvda2,w'',
>

>              ]
...means that the two virtual disks in your regarding DomU are file based,
placed as files:

/vmstore//domains/VM4LiveFS/disk.img
...

(btw: the (double) slashes "//" should be changed into one
"/".

If they are not there (even when the DomU is started) you might use the wrong
config file here. When the DomU is running you may look after it too by:

xm block-list
or 
xl block-list
and
losetup -a

(from mind, pls check the correct syntax by help if required)


hth,

best regards,


Niels.
