Thread-topic: Exporting "SD" device.
Hi,
 
We have Intel VT enabled system loaded with Xen 3.0.2 and qemu based FC5+linux 2.6.16 as a guest operating system. We want to export the disk to the domain 1 (FC5_linux 2.6.16) as "SD" device. But we are not able to export the SCSI disk as a SD device, we could export as a "HD" device.
 
In the Configuration file,

disk = [ 'file:/home/adteam/linux_fc5_2.6.16,ioemu:hda,w','phy:/dev/sdd,ioemu:hdb,w' ]

if we use ioemu:hdb, then the device is exported to the domain 1 and we could see the device.

If we use

disk = [ 'file:/home/adteam/linux_fc5_2.6.16,ioemu:hda,w','phy:/dev/sdd,/dev/sdb,w'

/dev/sdb, then the device is not seen on domain 1.

Are we missing something. Is it not possible to export an SD device to domain 1? Is there any limitiation in qemu based domain 1, because our domain 0 is qemu based operating system.

Is there any performance difference between "hda" and "sda" exported devices???

Thanks.
