Re: [Publicity] Seems the VM vs container debate is heating up

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Given that most people only use one VM for one task, the rise of
"micro-VMs" makes sense, whether they are based on OSv (miniOS or rump
kernels) on traditional hypervisors or on Docker, ZeroVM or other types
of containers.

However what these articles don't take into account is that Xen can
already handle both kind of workloads extremely well: Xen can handle fat
old-style VMs, with HVM guests, and new style lightweight micro-VMs,
with miniOS (or rump kernels or OSv) inside a PV guest.

If I manage to carve the time to do it I might be able to write a blog
post about it.
