Debugging an MP guest doesn't work. It appears that if a vcpu other than 0 hits an int3 it doesn't get paused. If the comment in domain_pause_for_debugger is correct (below), this function is completely inappropriate for breakpoint debugging. NOTE: Thise does not synchronously pause the domain. The debugger must issue a PAUSEDOMAIN command to ensure that all execution has ceased and guest state is committed to memory. What is the correct way to synchronously deschedule a domain? Replacing vcpu_sleep_nosync with vcpu_sleep_sync causes dom0 to lock up when hitting a breakpoint. Thanks. -Kip _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
