Abstract
The disclosure provides an approach for upgrading a virtual machine (VM) using an instant clone. A method includes initiating updating of the VM on a host in a datacenter; creating a clone of the VM on the host, in response to initiating the update; receiving a first write input/output (I/O) request for a first data block; checking a first disk bitmap associated with a first delta disk for whether a first bit associated with the first data block is set; based on the first bit being set, checking a scanner bitmap for whether a second bit associated with the first data block is set; and based on the second bit being set: waiting until the first data block is merged into a second disk; and performing the first write I/O to the first data block in the second disk after the first data block is merged into the second disk.
