Public bug reported:
I tried to open a qcow2 file with qemu-nbd and backup the files in it.
After some coping I get lot of I/O errors in dmesg and the system hangs.
One time I got even a kernel panic (Of course on a productive Server ;-)
)
How to reproduce:
1. Connect nbd to a qcow2 file, a virtual machine mustn't use this file:
qemu-nbd --connect=/dev/nbd0 /mnt/qcow/andromeda.qcow2
2. Read some data from /dev/nbd0p1
dd if=/dev/nbd0p1 of=/dev/null bs=1M
After a few Seconds till Minutes somethings crash's
Attached some dmesg logs
