[libvirt] [PATCH 0/9] RISC-V Guest Support

[Lubomir Rintel]

Hello,

here's patches I've used in order to be able to run RISC-V guests with
libvirtd. In case you're interested in having RISC-V support you may
want to have a look.

There are some problems I am aware of, though not really able to
address. I might be wrong about some points -- whoever is more familiar
with QEMU, RISC-V or libvirt please correct me:

* Essentially only the "virt" machine is useful, because others don't
  seem to support storage or network (as of qemu-2.12). It is not
  default though, so creating a reasonable guest configuration is not
  intuitive.

* The serial port used by the "virt" machine is NS16550A connected to
  the platform bus, but it doesn't seem to appear in the QEMU device
  model. I hardcoded it in qemuChrIsPlatformDevice() and
  qemuDomainChrDefPostParse() so that we end up defaulting to the
  correct one for the virt machine.

* The tests were in a large part cargo-culted. I made some effort
  to cover what I thought was important, but it likely needs a better
  pair of eyes than mine. More in the idividual patches.

In any case, I am able to boot Fedora and things seem to work well in
general. I'll be thankful for feedback (and even more thankful if anyone
more familiar with libvirtd picks up the patchset :).

Hope this is useful,
Lubo
