...t4 error when testing virtio_scsi & vhost_scsi No issue: 1. virtio_scsi, ext4 2. vhost_scsi & virtio_scsi, ext2 3. Instead of vhost, also tried loopback and no problem. Using loopback, host can use the new block device, while vhost is used by guest (qemu). http://www.linux-iscsi.org/wiki/Tcm_loop Test directly in host, not find ext4 error. Have issue: 1. vhost_scsi & virtio_scsi, ext4 a. iblock b, fileio, file located in /tmp (ram), no device based. 2, Have tried 4.7-r2 and 4.5-rc1 on D02 board, both have issue. Since I need kvm specific patch for D02, so it may not freely to switch...

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, This series contains patches required to update tcm_vhost <-> virtio-scsi connected hosts <-> guests to run on v3.5-rc2 mainline code. This series is available on top of target-pending/auto-next here: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git tcm_vhost This includes the necessary vhost
