Unable to read USB filesystems with EFI Bios
Status in QEMU:
Preamble and version:
With respect to my fix for using USB devices as -hda mentioned in bug 1223467
Using Qemu 1.6.0 with OVMF r11337-alpha (Qemu is built from Source, OVMF is
qemu-system-i386.exe -m 1024 -hda \\.\PhysicalDrive1 -L ovmf-ia32
The EFI Shell is able to detect the hda block device, report its capacity and
but it sees no files or directories on the device.
I have also seen the same with
qemu-system-x86_64.exe -m 1024 -hda \\.\PhysicalDrive1 -L ovmf-ia32
qemu-system-x86_64.exe -m 1024 -hda \\.\PhysicalDrive1 -L ovmf-x64
I tried very small (500MB) and very large (32 GB) USB devices with no
I re-built several versions of Qemu in an identical build environment, and
Qemu 1.2.2 and before, all the above commands work and the EFI boot loader is
Qemu 1.3.0-rc0 and after do not work and the USB device appears blank.
I'm reporting the bug here and not with OVMF because older versions of Qemu
with the same OVMF bios work perfectly.
In all cases using '-L pc-bios' works perfectly.
In all cases using an image of the USB device works.
