Subject: [PATCH 5/5] vhost-user-scsi: prevent using uninitialized vqs
|
|
|
|
Of the 3 virtqueues, seabios only sets cmd, leaving ctrl
|
|
and event without a physical address. This can cause
|
|
vhost_verify_ring_part_mapping to return ENOMEM, causing
|
|
the following logs:
|
|
|
|
qemu-system-x86_64: Unable to map available ring for ring 0
|
|
qemu-system-x86_64: Verify ring failure on region 0
|
|
|
|
The qemu commit e6cc11d64fc998c11a4dfcde8fda3fc33a74d844
|
|
has already resolved the issue for vhost scsi devices but
|
|
the fix was never applied to vhost-user scsi devices.
