Hello all,
Our current setup is based on Xen 4.11 + Qemu 3.1 with rbd disks, an example of a disk that works : "vdev=xvda1,backendtype=qdisk,target=rbd:rbd-pool/disk-02-root:id=rbd”.
The same setup with Qemu 5.0 gives this error in /var/log/xen/qemu-dm-* : "qemu-system-i386: failed to create 'qdisk' device '51713': failed to create drive: Could not open 'rbd:rbd-pool/disk-02-root:id=rbd': No such file or directory”
Looking at the source in xen-block.c it looks like the driver is forced to “file” which wouldn’t work for other type of block devices.
It looks like a regression with the xen-disk introduction.
Regards,
Antoine
