Package: qemu-system-x86 Version: 1:4.1-1 Severity: normal File: qemu-system
Dear Maintainer,
Using a pre-opened file descriptor to a disk image no longer work as
documented (and as it used to with ≤1:3.1+dfsg-8~deb10u1):
$ touch /tmp/disk.img
$ qemu-system-x86_64 -display none \
-add-fd "fd=3,set=0" \
-drive "file=/dev/fdset/0,format=raw,media=disk" \
3<>/tmp/disk.img
qemu-system-x86_64: -drive file=/dev/fdset/0,format=raw,media=disk: Could
not open '/dev/fdset/0': Permission denied
Interestingly, for read-only media it does work if the file descriptor
is opened in read-only mode:
$ qemu-system-x86_64 -display none \
-add-fd "fd=3,set=0" \
-drive "file=/dev/fdset/0,format=raw,media=cdrom,readonly" \
3</tmp/disk.img
