Hello, I''m a grad student working at University of Michigan in computer architecture. I''m writing to open up the idea that instrumentation of the xvm would be extremely useful tool for the research community. Those of us interested in virtualization are very interested in monitoring the behavior of these systems and with low engineering effort! I was hoping to get feedback on

I would also like to help as well. As KMacy knows before i asked a lot of questions for T2 types of servers but unfortunately i have no more access to those kind of hardware as well. I;m willing to participate if a team will be formated.

...ugh pockets you can buy servers. Sparc/ - If you have deep enough pockets Oracle will sell you servers. You can probably find something workstation-y on ebay (talk to netbsd folks apparently http://wiki.netbsd.org/ports/sparc/ http://wiki.netbsd.org/ports/sparc64/). You can also probably synthesize OpenSPARC for an FPGA setup in the <$10,000 range. SystemZ/ - If you have deep enough pockets IBM will sell you one. WebAssembly/ - You can probably pull some sort of bleeding edge V8 or Mozilla repo. (being developed in the open, so "obvious" I guess) X86/ - obvious XCore/ - There are dev board...

You've raised an important point here Pete, and while I disagree pretty strongly with it (regardless of whether Lanai makes sense or not), I'm glad that you've surfaced it where we can clearly look at the issue. The idea of "it really should have users outside of just the people who have access to the HW" I think is deeply problematic for the project as a whole. Where does

...I propose here, there are two places where Xen has to react on. I) Xen receives a MCE from the CPU and II) Xen receives Dom0 instructions via Hypercall The term "self-healing" below is used in the sense of using the most propriate technique(s) to handle an error such as MPR (http://www.opensparc.net/pubs/papers/MPR_DSN06.pdf), online-spare RAM or killing/restarting of impacted processes to prevent crashes of whole guests or the whole machine. case I) - Xen reveives a MCE from the CPU 1) Xen MCE handler figures out if error is an correctable error (CE) or uncorrectable error (UE) 2a)...
