Abstract
Implementations for providing random data to a guest operating system are disclosed. In one implementation, a method of the disclosure comprises: receiving, by a processing device of a host computer system, a first random data item from an external computer system; updating an entropy pool using the first random data item; and providing a virtual machine running on the host computer system with a second random data derived from the host entropy pool.
Claims20
A method comprising:
- receiving, using a processing device of a first host computer system, a first random data item from an external computer system;
- updating an entropy pool using the first random data item;
- and
- providing a first virtual machine running on the first host computer system with a second random data item derived from the entropy pool.
A system comprising:
- a memory device;
- and
- a processing device of a host computer system, communicably coupled to the memory device, to:
- receive a first random data item from an external computer system;
- determine that the external computer system is authorized to provide random data to virtual machines associated with a user of the host computer system;
- update an entropy pool using the first random data item in response to determining that the entropy pool is associated with the user;
- and
- provide a virtual machine running on the host computer system with a second random data item derived from the entropy pool.
A non-transitory machine-readable storage medium including instructions that, when accessed by a processing device of a host computer system, cause the processing device to:
- receive, by the processing device, a first random data item from an external computer device;
- update an entropy pool using the first random data item;
- and
- provide a virtual machine running on the host computer system with a second random data item derived from the entropy pool.
