gdbsx missing

Apologies, it is in xen-utils in /usr/lib/xen-4.4/bin/ which is why I couldnt find it... not in any normal PATH. Can close this.

It's not in xen-utils-4.7 on Ubuntu 16.10 (yakkety) though!

Looks like the build does not place it into the expected path. I'll have to look into this. Might take a bit, though.

This bug was fixed in the package xen - 4.8.0-1ubuntu1

---------------
xen (4.8.0-1ubuntu1) zesty; urgency=medium

  * Merge from Debian unstable. Remaining changes:
    - Add transitional package definitions to debian/control and
      debian/rules.gen (force hypervisor upgrade).
    - Split xen.init into xenstored.init and xen.init
      * xen.init depends in xenstored.init and optionally schedules itself
        before libvirtd.
      * xenstored.init additionally modprobes xen-acpi-processor
    - Remove update-alternatives call from xen utils (postinst/prerm) scripts.
    - Copy contents of debian/build/install-utils_$(ARCH)/usr/sbin into
      debian/build/install-utils_$ARCH/usr/lib/xen-$(VERSION) (LP: #1396670).
