摘要： A fault-tolerant virtualized computer system comprises a primary host executing a primary virtual machine (VM) and a backup host executing a backup VM. In one embodiment, each VM includes a virtual disk mapped to a shared disk image on physical disk accessible to both hosts. A virtual disk IO request is received by virtualization software executing on the backup host from a backup VM. When the virtual disk IO request is a read request, the virtual disk IO request is mapped to a physical read IO request of a virtual disk image stored on a physical disk, the physical read IO request is issued to the physical disk. However, when the virtual disk IO request is a write request, it is assumed to be completed without mapping the virtual disk IO request or issuing a mapped physical IO request to the physical disk.

摘要： A source virtual machine (VM) hosted on a source server is migrated to a destination VM on a destination server without first powering down the source VM. After optional pre-copying of the source VM's memory to the destination VM, the source VM is suspended and its non-memory state is transferred to the destination VM; the destination VM is then resumed from the transferred state. The source VM memory is either paged in to the destination VM on demand, or is transferred asynchronously by pre-copying and write-protecting the source VM memory, and then later transferring only the modified pages after the destination VM is resumed. The source and destination servers preferably share common storage, in which the source VM's virtual disk is stored; this avoids the need to transfer the virtual disk contents. Network connectivity is preferably also made transparent to the user by arranging the servers on a common subnet, with virtual network connection addresses generated from a common name space of physical addresses.
摘要翻译： 托管在源服务器上的源虚拟机（VM）将迁移到目标服务器上的目标VM，而无需首先关闭源虚拟机。 在将源虚拟机的内存可选地预先复制到目标虚拟机之后，源虚拟机被暂停，其非内存状态被传送到目标虚拟机; 目的地VM然后从转移状态恢复。 根据需要将源VM内存分页到目标虚拟机，或通过预源复制和写保护源虚拟机内存异步传输，然后在目标虚拟机恢复之后稍后传输修改的页面。 源服务器和目标服务器优选地共享存储源虚拟机的虚拟盘的公共存储器; 这避免了传输虚拟磁盘内容的需要。 优选地，通过将服务器布置在公共子网上，通过从物理地址的公共名称空间生成的虚拟网络连接地址，网络连接性也对用户透明。

摘要： A virtual machine (VM) runs on system hardware, which includes a physical network interface device that enables transfer of packets between the VM and a destination over a network. A virtual machine monitor (VMM) exports a hardware interface to the VM and runs on a kernel, which forms a system software layer between the VMM and the system hardware. Pending packets (both transmit and receive) issued by the VM are stored in a memory region that is shared by, that is, addressable by, the VM, the VMM, and the kernel. Rather than always transferring each packet as it is issued, packets are clustered in the shared memory region until a trigger event occurs, whereupon the cluster of packets is passed as a group to the physical network interface device. Optional mechanisms are included to prevent packets from waiting too long in the shared memory space before being transferred to the network. An interrupt offloading mechanism is also disclosed for use in multiprocessor systems such that it is in most cases unnecessary to interrupt the VM in order to request a VMM action, and the need for VMM-to-kernel context transitions is reduced.

摘要： A container for storing a silicone hydrogel contact lens in a liquid, having a bowl portion with a radius such that the radius of the lens is from about 85 percent to about 100 percent of the inner surface radius. The bowl portion has an outer section which is defined by a radius larger than the inner surface radius. Furthermore, the bowl portion has a roughness sufficient to maintain capillary attraction of the lens to the bowl portion but preventing adhesion of any portion of the front surface of the lens to the bowl portion.

摘要： An engine (TOE) is provided in a virtualized computer system for offloading I/O tasks using any defined protocol such as TCP/IP. The system includes a virtual machine (VM), which has a guest operating system (OS) that runs via a virtual machine monitor (VMM) on a system-level software platform (vmkernel), which also forms the software interface layer to at least one physical network connection device. A TCP/IP stack is included in vmkernel. During normal I/O operation, for sockets associated with TOE, processes in an application layer in the guest OS are able to communicate directly with vmkernel's TCP/IP stack, thereby bypassing the guest OS kernel.
