Re: [Qemu-devel] [RFC] block io lost in the guest , possible related to qemu?

2013-10-28 Thread Alexey Zaytsev
wonder is it possible the workload generate some unknown reqests to qemu that lost in virtio_blk_handle_read? I do some fio test myself, I cann't generate so call unknown request type. Any response will be helpful. Jack commit 9e72c45033770b81b536ac6091e91807247cc25a Author: Alexey Zaytsev

[Qemu-devel] [RFC] virtio-block serial number.

2012-12-19 Thread Alexey Zaytsev
Hi. Would it be a good idea to provide some non-empty serial number for VIRTIO_BLK_T_GET_ID, when the user does not specify one? QEMU assigns a default serial to IDE drives, but not virtio.

Ok, so I just installed the current OpenIndiana development build (http://dlc.openindiana.org/isos/148/oi-dev-148-text-x86.iso) on AHCI and booted from it. It works just fine for me :). Confirmed, works after a clean install. I'll see if I can get it into non-working state.
