Package: qemu-system-x86
Version: 1:5.2+dfsg-3~bpo10+1
Severity: normal

Dear Maintainer,

According to the man page for qemu (qemu-system-x86_64) it should be possible
to use a URL to point to a read only ISO image, with an example given to boot
from a remote Fedora 20 live ISO image.

eg
qemu-system-x86_64 --drive media=cdrom,file=http://<link to iso>,readonly

Any attempt to do this with the qemu binaries distributed in Debian gives the
error:

Unknown driver 'http'
or
Unknown driver 'https'

I suspect this may be because the Debian binaries are compiled without the
--enable-curl flag, as I'm not seeing libcurl4 in the list of dependencies.

Is this deliberate?

Thanks,

Rob Leadbeater

I suspect this may be because the Debian binaries are compiled without the

Please install qemu-block-extra package.

Is this deliberate?

Yes.

Thanks,
