Thread-topic: [Xen-users] VmError: Disk image does not exist

You need to execute this command on the image which you would have created

 

For example from your configuration file looks like /home/xen/domains/win01/disk.img is the image file you are using to install OS.

 

So execute the commands on this image file. If still it is throwing error. Copy your image file to /var/lib/xen/images and then execute the commands.

thanks venkat,
                        i have tried these command but i am getting error as..

root@boss[~]#semanage fcontext -a -t xen_image_t /home/xen/domains
libsepol.context_from_record: type xen_image_t is not defined
libsepol.context_from_record: could not create context structure
libsemanage.validate_handler: invalid context system_u:object_r:xen_image_t specified for /home/xen/domains [all files]
libsemanage.dbase_llist_iterate: could not iterate over records
/usr/sbin/semanage: Could not add file context for /home/xen/domains

also can you tell me KERNEL_IMAGE_PATH means which path..path to where .img we are going to craete or path of vmlinuz-xen??

Try to run these commands on your Kernel image and see.

builder = 'hvm'
memory = '256'
device_model='/usr/lib/xen-3.0.3-1/bin/qemu-dm'

# Disks
disk = [ 'file:/home/xen/domains/win01/disk.img,ioemu:hda,w',
'file:/root/WINDOWS_2003_STANDARD.ISO,ioemu:hdb:cdrom,r' ]

# Hostname
name = 'win02'

# Networking
