similar to: [Virtio-for-kvm] [PATCH 3/7] userspace virtio

This patch adds a 'raid' interface class. It is basically a clone of the existing 'scsi' interface, only allowing up to 128 disks.

virtio-net (non-vhost) and virtio-blk have everything in place to support virtio 1.0: let's enable the feature bit for them. Note that VIRTIO_F_VERSION_1 is technically a transport feature; once every device is ready for virtio 1.0, we can move this setting this feature bit out of the individual devices.

Hmm I doubt that. At least not without more patches. For block, scsi, wce and config-wce must be off, and it must support ANY_LAYOUT (which might be a bit more code). For net, header size is

Wire up virtio-blk to provide different feature bit sets depending on whether legacy or v1.0 has been requested. Note that VERSION_1 is still disabled due to missing ANY_LAYOUT support.

I'm sending a first draft of my proposed cpu hotplug driver for kvm/virtio The first patch is the kernel module, while the second, the userspace pci device. The host boots with the maximum cpus it should ever use, through the -smp parameter. Due to real machine constraints (which qemu copies), i386 does not allow for any addition of cpus after boot, so this is the most general way. I do
