NAME
rumpuser -- rump hypervisor interface
LIBRARY
rump User Library (librumpuser, -lrumpuser)
SYNOPSIS
#include <rump/rumpuser.h>
DESCRIPTION
rumpuser is the hypervisor interface for rump(3) style kernel virtualiza- tion. A virtual rump kernel can make calls to the host operating system libraries and kernel (system calls) using rumpuser interfaces. Any "slow" hypervisor calls such as file I/O, sychronization wait, or sleep will cause rump to unschedule the calling kernel thread from the virtual CPU and free it for other consumers. When the hypervisor call returns to the kernel, a new scheduling operation takes place. For example, rump implements kernel threads directly as hypervisor calls to host pthread(3). This avoids the common virtualization drawback of multiple overlapping and possibly conflicting implementations of same functionality in the software stack. The rumpuser interface is still under development and interface documen- tation is available only in source form from src/lib/librumpuser.
