Hello, This is v2 of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version. Limiting disk size is not implemented yet. * changes in v2) - update VIRTIO_ID_PSTORE to 22 (Cornelia, Stefan) - make buffer size configurable (Cornelia) - support PSTORE_TYPE_CONSOLE (Kees) - use separate virtqueues for read and write - support concurrent async

Hello, This is another iteration of the virtio-pstore work. I've addressed all comments from Daniel Berrange on the qemu side. * changes in v4) - use qio_channel_file_new_path() (Daniel) - rename to delete_old_pstore_file (Daniel) - convert G_REMOVE_SOURCE to FALSE (Daniel) * changes in v3) - use QIOChannel API (Stefan, Daniel) - add bound check for malcious guests

Hello, This is another iteration of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version and drooped the support for PSTORE_TYPE_CONSOLE for simplicity. It'll be added once the basic implementation * changes in v3) - use QIOChannel API (Stefan, Daniel) - add bound check for malcious guests (Daniel) - drop support PSTORE_TYPE_CONSOLE for now
