Syntax

Hierarchy Level

Description

Specify the VNF image source file. VNF image is virtual hard disk, which contains the bootable file-system for the VNF.

Options

`file-path`	Path of the image source file
image-type	Format of the image. Default value is qcow2.
bus-type	Type of the system bus. Default value is virtio.
driver-cache	Type of the driver cache mode. Default mode is default-cache default-cache—Default mode when you do not specify any driver cache mode. directsync—Enables the hypervisor to interact with the disk image file or block device with both `O_DSYNC` and `O_DIRECT` semantics. The hypervisor reports that the writes are completed only when the data is committed to the storage device, and when it is also desirable to bypass the host page cache. none—Enables the hypervisor to interact with the disk image file or block device with `O_DIRECT` semantics. The hypervisor bypasses the host page cache and I/O happens directly between the hypervisor user space buffers and the storage device. y. unsafe—Ignores all flush commands from the guests. Using this mode implies that the user has accepted the trade-off of performance over risk of data loss in case of a host failure. writeback—Enables the hypervisor to interact with the disk image file or block device with neither `O_DSYNC` nor `O_DIRECT` semantics. The hypervisor uses the host page cache and reports the writes to the guest as completed when the writes are in the host page cache. writethrough—Enables the hypervisor to interact with the disk image file or block device with `O_DSYNC`semantics. The hypervisor reports the writes as completed only when the data is committed to the storage device.
