A panic usually contains a message with the reason of the panic. Roger.

Xen also supports printing to a USB debug port (EHCI debug port) [0], but some laptops don't even have the USB debug port accessible, and then you need a special adapter which is impossible to find nowadays. So, the easier way to debug is to get a box with SOL or a working serial DB9 port. Roger.

I have solved this problem for me by renting a physical server at the hosting company. But serious hacking requires having access to the physical console (most hosting providers provide something like that). I don't know how others are working on this? Anyone running Xen on their laptop for example? Marcin smime.p7s Description: S/MIME Cryptographic Signature

One more thing, is there any other VM like VirtualBox that can run Xen + FreeBSD as Dom0, or do I have to run it on a different computer.

Anyway, I can't get the logs because they are not outputting to the serial port for some reason. I wrote what I could read from the 5 seconds I get before the reboot in my first email. You answered my question, but if you want a look at the error message I could read, check my first email. I'll also paste it below [0].

Yes, I think you will need to be able to run Xen + FreeBSD. You can probably manage to complete the first part using Xen + Linux and running FreeBSD as a guest, but you will need Xen + FreeBSD Dom0 for the second part (adding handlers for mapping operations used by the backend). > Also, how can I fix the error I'm currently getting about Intel > processor not being supported?

I am working on the Xen grant table handlers (for my Google Summer of Code project [0]) , so do you think I would need to run Xen + FreeBSD when testing?

It's likely possible to run Xen + Linux Dom0 inside of VirtualBox, but it's almost certainly not possible to run Xen + FreeBSD inside of VirtualBox because it would require an emulated IOMMU, which I don't think VirtualBox provides.
