This is your roving LUG reporter writing to you from this evening's meeting of Lug/IP (LUG In Princeton).
2003, October 15, Wednesday evening The topic tonight is UML (User Mode Linux), a presentation by Mark Huang. UML (User Mode Linux) is about running a linux kernel in user space (rather than kernel space). Doing so runs the kernel and an entire virtual machine within a user process. The magic (programing of UML) has to do with redirecting the interrupts and device communication, handled by the kernel, to software control running within UML, or UML kernel. The result is that an entire virtual machine can be created within a single user process. All of it's file i/o and swap and paging activity is done to a single file on the file system of the native OS. The native OS is one that is really running on the machine and the one that is hosting the UML kernel running as a process in user (mode) space. Correction: UML will spawn multiple processes in the process table in the native OS. The capability this offers, and the guts of how it works were the topics of tonights presentation.
