Create Child from Parent
Disk
Usually you create the first child disk from the
parent and create successive children from the latest one in the chain. The
disk tracks, in
SPARSE
format, any disk
sectors changed since inception, as illustrated below.
Child disks
created from parent
VixDiskLib_CreateChild()
creates a child disk
(or redo log) for a hosted virtual disk. After you create a child, it is
generally not necessary to open the parent, or earlier children in the disk
chain. The children’s
vm.vmdk
files point to redo
logs, not to the parent disk,
vm-flat.vmdk
in this
example. To access the original parent, or earlier children in the chain, you
can use
VixDiskLib_Attach()
on hosted
disk.
vixError = VixDiskLib_CreateChild(parent.Handle(), appGlobals.diskPath, VIXDISKLIB_DISK_MONOLITHIC_SPARSE, NULL, NULL);
