Hi,
I am using xen 4.3.2 and trying to hotplug usb flash drives. I have a
Fedora 20 host and a Windows 7 DomU (hvm).
When using "xl block-attach" I can successfully attach a USB-device in
write mode and make changes to it in DomU. They are only saved to the
USB if I detach it from within the Dom0 ("xl block-detach").
In Windows there is no option to safely eject though because the
device is seen as a hard drive.
I am thinking this has to do with Windows writing to the memory first
for performance reasons.
With flash drives imo Windows writes straight to the drive to prevent data loss.
Is there a way to let the Windows DomU recognize the device as a USB
flash drive?
The command I am using right now looks like this:
xl block-attach windows phy:/dev/sdb1 sdb w
Thank you for your help
Franz
