A pneumatic line is configured to inflate the upper packer and the lower packer, and an injection line is configured to provide leachate solution through the high dispersion screen. The dual packer assembly is configured to deliver the leachate solution through the high dispersion screen to an interval of the borehole bounded by the upper packer and the lower packer.

Abstract: Systems and methods for memory management for guests. An example method may include running, by a host computer system, a host component managing a guest in communication with a peripheral device, wherein the peripheral device comprises an input/output memory management unit (IOMMU). The method may further include appending, to a page table of the IOMMU, a plurality of records referencing present memory pages associated with a task running on the guest and appending, to the page table of the IOMMU, a plurality of records referencing read-only memory pages associated with the task, wherein the read-only memory pages are indicated as read-only in the page table.

Abstract: Aspects of the disclosure provide for mechanisms for memory protection of virtual machines in a computer system. A first host page table and a second host page table is generated by a processing device running a hypervisor in view of a guest page table associated with a virtual machine. The first host page table includes a first mapping corresponding to a privileged page of a guest memory and a second mapping corresponding to an unprivileged page of the guest memory. The second host page table includes a third mapping corresponding to the unprivileged page of the guest memory. The first host page table is associated with the virtual machine. In response to detecting a transition from a first guest mode to a second guest mode by the virtual machine, the virtual machine is associated with the second page table.

Abstract: Systems and methods for memory management for virtual machines. An example method may include generating, by a Peripheral Component Interconnect (PCI) device comprising an input/output memory management unit (IOMMU), a first bit sequence and generating a second sequence by applying a predetermined transformation to the first bit sequence. The method may then write the second bit sequence to a memory buffer, read a first value from the memory buffer, write the first bit sequence to the memory buffer, and read a second value from the memory buffer. Responsive to determining that the second value does not match the first value, the method may associate a writable attribute with an IOMMU page table entry associated with the memory buffer.
