Changes to support Veritas HyperScale (VxHS) block device protocol with qemu-kvm.
Where is the corresponding QEMU patch for this block device protocol ?
Unless I've missed it, I've not seen it on qemu-devel yet.
As mentioned on the previous review, I really very much doubt the
syntax you're showing here is going to be accepted by QEMU:
+-drive
file=vxhs://192.168.0.1:9999/%7Beb90327c-8302-4725-9e1b-4e85ed4dc251%7D\
+vxhs://172.172.17.56:9999/%7Beb90327c-8302-4725-9e1b-4e85ed4dc251%7D,\
+format=raw,if=none,id=drive-virtio-disk0,cache=none \
I really expect you will have to create a proper QAPI schema for expressing
the block device configuration and *not* use the URI format, since the
latter has fallen out of favour with QEMU maintainers.
There's honestly not a much point in reviewing this libvirt code until
there is some certainty around the QEMU design, because it'll cause
significant change to the code in libvirt for formatting the command
line.
