Abstract: Autonomous selection between multiple virtualization techniques implemented in a virtualization layer of a virtualized computer system. The virtual machine monitor implements multiple virtualization support processors that each provide for the comprehensive handling of potential virtualization exceptions. A virtual machine monitor resident virtualization selection control is operable to select between use of first and second virtualization support processors dependent on identifying a predetermined pattern of temporally local privilege dependent instructions within a portion of an instruction stream as encountered in the execution of a guest operating system.

Abstract: Mechanisms to protect the integrity of memory of a virtual machine are provided. The mechanisms involve utilizing certain capabilities of the hypervisor underlying the virtual machine to monitor writes to memory pages of the virtual machine. A guest integrity driver communicates with the hypervisor to request such functionality. Additional protections are provided for protecting the guest integrity driver and associated data, as well as for preventing use of these mechanisms by malicious software. These additional protections include an elevated execution mode, termed “integrity mode,” as well as protections on the memory pages that store the guest integrity driver. To prevent spurious alerts associated with the GI driver accessing its own data, the hypervisor maintains two page tables. In one copy, pages storing data for the GI driver are not protected and in the other, those pages are protected. The hypervisor switches the page tables when entering and exiting integrity mode.

Abstract: Techniques for dynamically using system (i.e., VM guest) memory as video memory for virtual graphics processing units (VGPUs) are provided. In one embodiment, a guest graphics driver running within a virtual machine (VM) of a host system can receive, from a guest application of the VM, a request to create a graphics resource. The guest graphics driver can then dynamically allocate, in response to the request, a memory object for the graphics resource in a guest memory space of the VM.

Abstract: A virtual machine (VM) is migrated from a source host to a destination host in a virtualized computing system, the VM having a plurality of virtual central processing units (CPUs). The method includes copying, by VM migration software executing in the source host and the destination host, memory of the VM from the source host to the destination host by installing, at the source host, write traces spanning all of the memory and then copying the memory from the source host to the destination host over a plurality of iterations; and performing switch-over, by the VM migration software, to quiesce the VM in the source host and resume the VM in the destination host. The VM migration software installs write traces using less than all of the virtual CPUs, and using trace granularity larger than a smallest page granularity.

Abstract: System and method for providing fault tolerance in virtualized computer systems use a first guest and a second guest running on virtualization software to produce outputs, which are produced when a workload is executed on the first and second guests. An output of the second guest is compared with an output of the first guest to determine if there is an output match. If there is no output match, the first guest is paused and a resynchronization of the second guest is executed to restore a checkpointed state of the first guest on the second guest. After the resynchronization of the second guest, the paused first guest is caused to resume operation.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for changing virtual machine user interfaces. One of the methods includes receiving a first request from a first client device to initiate a first remote session, detecting, for the first remote session, a first display property of the first client device in response to receiving the first request, configuring, for the first remote session, a virtual display device for the virtual machine to be a display device having the first display property, receiving a second request from a second client device to initiate a second remote session, detecting, for the second remote session, a second display property of the second client device in response to receiving the second request, and configuring, for the second remote session, the virtual display device for the virtual machine to be a display device having the second display property.

Abstract: In a computer system running at least a first virtual machine (VM) and a second VM on virtualization software, a computer implemented method for the second VM to provide quasi-lockstep fault tolerance for the first VM includes executing a workload on the first VM and the second VM that involves producing at least one externally visible output and comparing an externally visible output of the second VM with an externally visible output of the first VM to determine if there is an output match. In response to a determination that the externally visible output of the second VM does not match the externally visible output of the first VM, a resynchronization of the second VM is executed. The externally visible output of the first VM is kept from being output externally until completion of the resynchronization.
