The KTR trace would be useful to figure out what's happening. To do that you can compile the host kernel and vmm.ko with the following options: options KTR options KTR_MASK=(KTR_GEN) options KTR_ENTRIES=(4*1024*1024) And when you see the interrupt storm message in the guest you can execute: sudo ktrdump -cto /tmp/ktrdump.out best Neel > later, > > Peter. > > > _______________________________________________ > [email protected] mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization > To unsubscribe, send any mail to > "[email protected]" _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "[email protected]"
