[Xen-users] Error while booting a PV guest from an Image file

["Kumar, Venkat" <Venkat.Kumar@xxxxxxx>]

I created a PV guest on an Image file.

 

 

The configuration file is

 

=======================================================

kernel = "/home/venkat/RHEL_PV_Image/vmlinuz"

ramdisk = "/home/venkat/RHEL_PV_Image/initrd.img"

memory = 512

name = "RHEL-domu"

vif = [ '' ]

dhcp = ""

disk = [ 'file:/var/lib/xen/images/Rhel-domU.img,xvda,w']

=======================================================

 

Vmlinuz and initrd images are taken from the images/xen folder inside the installation CD.

I assume these two files will have PV drivers enabled kernel and isolinux/ directory will have unmodified vmlinuz and initrd images.

I used http as installation media.

This configuration file successfully installs the PV guest on the Rhel-domU.img image file using “xm create configfile”.

 

Now I need to boot my PV guest from the Rhel-domU.img image file. For that I changed the configuration file as

 

========================================================

bootloader = "/usr/lib/xen/boot/domUloader.py"

bootargs = "--entry=xvda1:/boot/vmlinuz-xen,/boot/initrd-xen.img"

memory = 512

name = "RHEL-domu"

vif = [ '' ]

dhcp = ""

disk = [ 'file:/var/lib/xen/images/Rhel-domU.img,xvda,w']

boot = "c"

========================================================

I added boot parameter and mentioned “c” option so that it boots from harddisk (this case it is a image file).

 

I get the following error while doing it.

 

Using config file "./Redhatconfig".

: No such file or directory

 

I did the same with the HVM guest and used hvmloader instead of domUloader and it worked fine.

I reckon that the bootargs that are provided are wrong.

 

Any idea about the error message?
