The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.

Title:
formating vdi-disk over nbd fails
Status in QEMU:
Incomplete
Bug description:
Hi,
after creating a vdi-image with qemu-vdi and attaching it with qemu-nbd partitioning works fine, but the system hangs up during formating with mkfs.ext4.
Same procedure with qcow2-image works fine
Tested on Fedora 31 kernel 5.5.7-200.fc31.x86_64
-----------------
#! /bin/sh
qemu-img create -f qcow2 ~/test.qcow2 32G
#qemu-img version 4.1.1 (qemu-4.1.1-1.fc31)
modprobe nbd max_part=8
qemu-nbd --connect=/dev/nbd2 ~/test.qcow2
#qemu-nbd 4.1.1 (qemu-4.1.1-1.fc31)
parted -s /dev/nbd2 "mklabel gpt"
parted -s -a optimal /dev/nbd2 "mkpart test ext4 2048 32G "
parted -s -a optimal /dev/nbd2 "p"
mkfs.ext4 /dev/nbd2p1
mkdir /mnt/test_qcow2
mount /dev/nbd2p1 /mnt/test_qcow2
df -H
-------------------
#! /bin/sh
qemu-img create -f vdi ~/test.vdi 32G
modprobe nbd max_part=8
qemu-nbd --connect=/dev/nbd4 ~/test.vdi
parted -s /dev/nbd4 "mklabel gpt"
parted -s -a optimal /dev/nbd4 "mkpart test ext4 2048 32G "
parted -s -a optimal /dev/nbd4 "p"
mkfs.ext4 /dev/nbd4p1
#Format hangs up due to IO errors
#Tested on Fedora 31 kernel 5.5.7-200.fc31.x86_64
mkdir /mnt/test_vdi
mount /dev/nbd4p1 /mnt/test_vdi
df -H
----------------------
Kind regards
