Cover letter [Qemu-devel] [PATCHv7 0/3] qemu: properties for feature compatibility
Here's what I came up with for solving the problem of differences in features in virtio between 0.12 and 0.11. This also enables migration between different backends, e.g. between host where tap supports virtio net header and where it does not: management just needs to set features appropriately.
Compat bits are yet to be set, will be done when this patch is applied.
changes since v6:
- fix arm-softmmu build
Changes since v5:
- added patch to rename features->guest_features
Changes since v4:
- Save bit offset in a separate field, offset is in bytes
Changes since RFC v2:
- we already have a flag to control write cache feature, let's not add another one
Changes since RFC:
- add symbolic names for properties
- only optional features can be changed
Michael S. Tsirkin (3):
qdev: add bit property type
virtio: rename features -> guest_features
virtio: add features as qdev properties
