This patch series introduces the tapback daemon, the user space daemon that acts as a device''s back-end, essentially most of blkback in user space. The daemon is responsible for coordinating the front-end and tapdisk. It creates tapdisk process as needed, instructs them to connect to/disconnect from the shared ring, and manages the state of the back-end. The shared ring between the

...achine and all associated ring/shared page setup is factored out into the xenidc_endpoint object and the driver code gets connect and disconnect callbacks from the endpoint instead. I''d like the otherend_changed entrypoint to be optional please. This will also let me remove the MixedCaps XenbusState typename from my code :-) I took the opportunity to implement suspend and resume in the frontend (and the backend to keep the code equivalent) though this is currently untested. I did a quick bit of testing and managed to mount the USB key again etc but had a few problems with module unload and r...

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than
