[Xen-devel] [PATCH for-4.5 0/2] Fix `xl vcpu-list` with partially created domains

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

This series fixes a bug to do with listing the vcpus of a domain lacking any.
This can occur if there was an error constructing a domain, and it wasn't
successfully cleaned up.

This series fixes two problems.  First that getdomaininfo() in Xen previously
had no way of expressing "this domain has no vcpus", and second that libxl
would blindly allocate memory with an uninitialised value in the case that it
encountered a domain in this state.

This bug was discovered against Xen 4.4, but the bug is present in -unstable
as well.  As such, I flag it for backport ASAP.
