I followed this procedure, where says that tap:aio should be used (isn't it rigth?): 
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Para-Virtualized_Windows_Drivers/sect-Para-Virtualized_Windows_Drivers-Installing_and_configuring_the_para_virtualized_drivers-Post_installation_host_configuration.html

With this configuration I saw three devices:
disk = [ "file:PathToMyImage.img,hda,w", "tap:aio:/dev/sda1,xvdb,w" ]

The devices are:

1) "c:" (10GB)
2) "QEMU HARDDISK" (50GB)
3) "RHEL DISK SCSI Disk Device" (50GB)
    
The only difference between 2) and 3) are in their Properties: 
2) says "Location: Location 1 (1)"    
3) says "Location: Bus Number 0, Target Id 0, LUN 1"

So I'm not sure if I should put my data in 2) or 3).

Thanks for your time.

Regards.

tap:aio should be for file-backed images, not devices. You should have

disk = [ "tap:aio:/PathToMyImage.img,hda,w", "phy:/dev/sda1,xvdb,w" ]

How many disks you have each? Do you have one or two QEMU disks?
QEMU harddisk should be hda, while RHEL disk should be xvdb.
