[Xen-devel] domain_crash_sync vs "plain crash"

[Charles Gonçalves <charles.fg@xxxxxxxxx>]

When I'm performing some hypercalls with some "unexpected" parameters (robustness test) sometimes the guest is explicitly  "killed" by xen calling the domain_crash(), but sometimes the guest just crash without any explicit message on dmesg or logs.

Are those "plain crashes" an expected behavior by design on Xen or are they some untreated parameter checking or something else?

Can someone comment about it?

Thanks!
