GUK (enhanced MiniOS) released

GUK (enhanced MiniOS) released

[-- Attachment #1.1: Type: text/plain, Size: 1085 bytes --]

I am pleased to announce the release of GUK (Project Guest VM 
Microkernel), which is an enhanced version of Mini-OS that underpins the 
Guest VM virtual machine. Guest VM is an implementation of the Java 
platform, written almost completely in Java, running directly on Xen. 
Although GUK was developed specifically for Guest VM, it can be used 
stand-alone in a similar way to Mini-OS.

The main differences between Mini-OS, when originally forked, and GUK are:

    * Support for multiple VCPUS (SMP)
    * Pre-emptive thread scheduling
    * Memory management tailored to a language run time virtual machine
    * Memory ballooning
    * Block device support
    * Suspend/Resume support

N.B. GUK has not been updated with any of the changes to Mini-OS since 
the initial fork.

The source code, which is licensed under GPL v2, can be found at 
https://kenai.com/projects/guestvm.
E.g.,

% hg clone https://kenai.com/hg/guestvm~guk guk

I'd like to acknowledge the significant contributions made by Grzegorz 
Milos and Harald Roeck during summer internships
at Sun.

Mick,
Thanks - this is interesting!  Is there a page with technical
information such as the boot-up time and how much memory it takes for
a minimal domain?  I notice the wiki is just getting started so
perhaps such information will be posted in due time?

Pulling it now, I'll play with it some.

Thanks,
Thomas

Sorry, should have noted that the documentation, such as it is (but more 
than Mini-OS), is in the "docs" subdirectory, or at 
http://research.sun.com/projects/guestvm/shared/guk/index.html

Fundamentally, it's not much more memory intensive or different in 
startup time from Mini-OS.
