Can you share the exact error message you're hitting? Our CI seems to
be perfectly happy with the current status quo. Specifically, the
x86-centos-7 job, the only one which is supposed to be able to build
the OpenVZ driver, is green.

Looking at the raw log[1] for the latest instance of the job, you can
see that the vz driver is enabled (vz: yes), but the vstorage driver
is not (Virtuozzo storage: no). From the configure output, the reason
seems clear:

  checking for vstorage... no
  checking for vstorage-mount... no

The CentOS 7 container that we use for builds has libprlsdk-devel and
friends installed from the official repository[2]... Although, now
that I look at it there's apparently a newer release[3] out, so we
should probably switch to it.


Another thing: the spec file calls configure with hardcoded

  --without-vz
  --without-storage-vstorage

and there is no binary package definition for anything like

  libvirt-daemon-driver-vz
  libvirt-daemon-driver-storage-vstorage

which would probably be nice to have enabled at least on CentOS 7?
Funnily enough, we actually already have

  %if 0%{?rhel}
    %define with_vz 0
  %endif

so clearly at some point there was the intention to conditionally
include or exclude these drivers from the build.


One thing at a time, though. First, how do we get the vstorage
commands included in the CentOS 7 container? What packages need to
be installed, and from what repository?


As an aside, I'm still very confused by the vz/openvz dichotomy.
AFAICT, the latter can be (and in fact is) built unconditionally,
but the former requires the "Parallels SDK" packages to be installed:
baffingly enough, said SDK is obtained from the repository mentioned
above, which just so happens to include the string "openvz" twice in
its URL...
