Subject: vhost-user-blk: Get more feature flags from vhost device
|
||
|
|
|
||
|
|
Git-commit: 7556a320c98812ca6648b707393f4513387faf73
|
||
|
|
|
||
|
|
VIRTIO_F_RING_PACKED and VIRTIO_F_IOMMU_PLATFORM need to be supported by
|
||
|
|
the vhost device, otherwise advertising it to the guest doesn't result
|
||
|
|
in a working configuration. They are currently not supported by the
|
||
|
|
vhost-user-blk export in QEMU.
|
||
|
