Secure digital host controller virtualization

A method of sharing a secure digital (SD) device amongst a plurality of hosts of a multi-host computing system, the method comprising:

• detecting, by a secured digital host controller (SDHC) virtualization unit, the SD device on occurrence of a reset event;
• receiving an enumeration request at the SDHC virtualization unit, from at least one of a first host and a second host from amongst the plurality of hosts, to enumerate the SD device with respect to the at least one of the first host and the second host;
• enumerating the SD device with respect to at least one of the first host and the second host, wherein the enumerating includes determining a type of SD device;
• activating, by a parsing logic of the SDHC virtualization unit, at least one of a Memory card (MC) parser and an Input/Output command/data (IOC) parser based on the type of the SD device in order to parse commands and requests received at the SDHC virtualization unit;
• and
• initiating data exchange, between the SD device and the at least one of the first host and the second host by activating of a functionality of the SD device, by at least one of the activated MC parser and the activated IOC parser.
