So I have two machines, both with xen installed. One has the dom0 and and unmodified hypervisor the other with a modified hypervisor to point at the dom0 on the other machine, they are linked via crossover cable.
I've looked into the source, and it seems i'd have to modify the DESTDIR. But what protocol would I use (TCP?) and how would I implement it? (packages?) Or am I just flat out wrong and this is impossible?
Accepted AnswerRussell PavlicekOnline0Jordan,
For a question of this sort, I strongly suggest sending an email to the xen-devel list. The skillset needed to do this is in the developer community, which congregates on xen-devel. See the Help > Mailing List menu for details.
From my limited perspective (I am not a hypervisor hacker), I tend to think this may not be the right approach. The Dom0 on each host has to supply the drivers and device models for that host. I doubt that the driver on one host could readily control the hardware on the other host.
What exactly are you trying to accomplish? If you want central control of multilple hypervisors across multiple hosts, you might want to explore the XAPI layer. It gives you the ability to manage workloads across multiple hosts, including VM migration, etc.
Is that what you need?
Accepted AnswerJordanOffline0I have looked into using alternatives to just govern the dom0's like XAPI, but for my application it wont do to well. If it is a driver issue I am sure I could get around it with standardized hardware, which actually is planned to be the final product. Though I would like to be able to upgrade as the time goes by with non standardized hardware, which is the main question at hand mainly because the prototype cannot be standardized.
Thank you for your response though and I will be emailing the dev's shortly.
