#### FIO Integrity tests

- NVMe device is split into 4 LUNs, each is attached to separate vhost controller

- FIO uses job configuration with randwrite mode to verify if random pattern was

  written to and read from correctly on each LUN

- runs on Fedora 25 and Ubuntu 16.04 guest systems

- runs against vhost scsi and vhost blk



#### Filesystem integrity

- runs SPDK with 1 VM with 1 NVMe device attached.

- creates a partition table and filesystem on passed device, and mounts it

- runs Linux kernel source compilation

- Tested file systems: ext2, ext3, ext4, brtfs, ntfs, fat

- runs against vhost scsi and vhost blk

#### vhost hot-remove tests

- removing NVMe device (unbind from driver) which is already claimed

- hotremove tests performed with and without I/O traffic to device

- I/O traffic, if present in test, has verification enabled

- checks that vhost and/or VMs do not crash

- performed against vhost blk and vhost scsi



#### vhost scsi hot-attach and hot-detach tests

- adding and removing devices via RPC to a controller which is already in use by a VM

- I/O traffic generated with FIO read/write operations, verification enabled

- checks that vhost and/or VMs do not crash

- checks that other devices in the same controller are unaffected by hot-attach
