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 Diffstat follows.
