### Vhost initiator test

Testing vhost initiator with fio write, randwrite, rw and randrw with verificiation enabled.

Tests include vhost-user (vhost initiator connecting to the socket on the same machine)

and virtio-pci (virtio initiator in a VM connecting to the virtual PCI SCSI device created by the hypervisor)

All tests are run in virtio-user mode. Tests 2-3, 5-9 are additionally run in virtio-pci mode.



#### Test Case 1 - vhost initiator test with malloc

1. Run vhost with one scsi controller and with one malloc bdev with 512 block size.

2. Prepare config for bdevio with virtio section.

3. Run bdevio test application with config.

4. Generate the fio config file given the list of all bdevs.

5. Run fio tests: iodepth=128, block_size=4k, rw, randwrite, write, randrw with verification.

6. Check if fio tests are successful.



#### Test Case 2 - vhost initiator test with nvme

1. Run vhost with one scsi controller and with one nvme bdev with 512 block size.

2. Repeat steps 2-6 from test case 1.



#### Test Case 3 - vhost initiator test with lvol

1. Run vhost with one scsi controller and with one lvol bdev with 512 block size.

2. Repeat steps 2-6 from test case 1



#### Test Case 4 - vhost initiator test with malloc

1. Run vhost with one scsi controller and with one malloc bdev with 4096 block size.

2. Repeat steps 2-6 from test case 1.



#### Test Case 5 - vhost initiator test with lvol

1. Run vhost with one scsi controller and with one lvol bdev with 4096 block size.

2. Repeat steps 2-6 from test case 1



#### Test Case 6 - vhost initiator test with nvme disk (size larger than 4G)

1. Run vhost with one scsi controller and with one nvme bdev with 512 block size and disk size larger than 4G

   to test if we can read, write to device with fio offset set to 4G.

2. Repeat steps 4-6 from test case 1.



#### Test Case 7 - vhost initiator test with multiqueue

1. Run vhost with one scsi controller (one malloc bdev and one nvme bdev).

2. Generate the fio config file given the list of all bdevs.

3. Run fio tests: iodepth=128, block_size=4k, rw, randread, randwrite, read, write, randrw with verify

4. Check if fio tests are successful.



### Test Case 8 - vhost initator test with multiple socket

1. Run vhost with two scsi controllers, one with nvme bdev and one with malloc bdev.

2. Generate the fio config file given the list of all bdevs.

3. Run fio tests: iodepth=128, block_size=4k, write with verification.

4. Check if fio tests are successful.



### Test Case 9 - vhost initiator test with unmap

1. Run vhost with one controller and one nvme bdev with 512 block size.

2. Run fio test with sequential jobs: trim, randtrim, write.

   All this jobs run with verification enabled.

   Use trim_verify_zero fio option to check if blocks are returned as zeroes.

   Write with verify after trim to check if we still can write and read from device.

3. Check if fio test ends with success.

4. Repeat steps 1-3 on host for malloc with 4096 block size and 512 block size.
