Hi, Avi Kivity, Dave Anderson
I have two questions about it:
1. How to know the guest's physical base address in qemu?
In fact, it's impossible.
Perhaps crash can scan through the core looking for a signature. Need
to be careful since multiple signatures may be detected (a kdump kernel,
a kernel image in pagecache, or a nested guest).
Crash uses a heuristic based on the IDT base to identify the base from
migrate-to-file output. It also needs CR3 in order to read from virtual
address.
