Cloud computing platforms having computer-readable media that perform methods to generate debuggable dump files are provided. The cloud computing platform includes server devices running operating system kernels. Optionally, the server may include a hypervisor. The operating system kernel receives a command to generate a debuggable dump file. In response, the operating system estimates memory requires to store the requested memory pages, allocates an appropriately sized buffer, and freezes computation. A hypervisor is present and if its memory pages are requested, the hypervisor freezes its computation. The hypervisor stores its memory pages in the buffer and resumes computation. The operating system kernel stores its pages to the buffer in priority order and resumes its computation. The contents of the buffer are written out as a debuggable dump file.

Cloud computing platforms having computer-readable media that perform methods to generate debuggable dump files are provided. The cloud computing platform includes at least one server having a host virtual machine, guest virtual machine, and hypervisor. The host virtual machine receives a command to generate the debuggable dump file. In response, it suspends all virtual processors executing on the guest virtual machine. The memory pages of the suspended virtual machine are written into a debuggable dump file, and the suspended processors are resumed at an appropriate time.

A virtual machine hosting environment executing on a physical machine is operable to instantiate a virtual machine that is capable of initiating I/O operations directed to a remote storage. The virtual machine hosting environment is operable to determine when an unavailability condition exists with respect to the remote storage and when such unavailability condition no longer exists. The virtual machine hosting environment is further operable to suspend the virtual machine based at least on the determination that the unavailability condition exists and to resume the virtual machine based at least on the determination that the unavailability condition no longer exists. The virtual machine hosting environment may be still further operable to save one or more pending I/O requests generated by the virtual machine in conjunction with pausing the virtual machine and to send the pending I/O request(s) to the remote storage in conjunction with resuming the virtual machine.
