- What do you see as the long term future of the driver ? I've
already asked whether there's any risk from future OpenVZ releases
potentially breaking things. Historically the idea with the kernel's
namespace support was that the OpenVZ forked kernel would be able
to go away. IIUC, the openvz userspace can already run on top of a
plain mainline kernel, albeit with reduced features compared to when
it runs on openvz kernel fork. If we assume the trend of merging
OpenVZ features into mainline continues, we might get to a point
where OpenVZ kernel fork no longer exists. At that point I wonder
what would be the compelling differences between BossonVZ and the
LXC driver ? ie why would we benefit from 2 container drivers for
the same kernel functionality.
Good point !
My recollection of talking with James Bottomley is indeed that all
the special features are being migrated as part of the commonly agreed
upon set of kernel primitives put in the kernel for containers. So I hope
that this driver will indeed work based on those primitives and not
the Parallels specific extensions, as those may vanish sooner or later.
What kernels do you support, only CentOS-6 modified ones ?
