Hello,
assuming that the VCPU is paused while waiting for userspace to respond
to a page fault mem_event, and userspace calls libxc's
xc_domain_hvm_getcontext_partial(... CPU ...) and tries to inspect RIP,
is this a safe thing to do? Is RIP's value guaranteed to be safe to
inspect in this context?
Thanks,
Razvan Cojocaru
