libxl fails to honour readonly flag on disks with qemu-xen
ISSUE DESCRIPTION Callers of libxl can specify that a disk should be read-only to the guest. However, there is no code in libxl to pass this information to qemu-xen the upstream-based qemu; and indeed there is no way in qemu to make a disk read-only. The vulnerability is exploitable only via...

FreeBSD : xen-tools -- HVM qemu unexpectedly enabling emulated VGA graphics backends (0d732fd1-27e0-11e5-a4a5-002590263bf5)
The Xen Project reports : When instantiating an emulated VGA device for an x86 HVM guest qemu will by default enable a backend to expose that device, either SDL or VNC depending on the version of qemu and the build time configuration. The libxl toolstack library does not explicitly disable these...
