bhyve VM crashed

  Probably no need, unless this can be repro'd by building that
particular port.

  Some more questions: Were there other VMs running at the same time ?
What's the type of host CPU/number of CPUs/amount of RAM ? Did the VM
have much uptime before the crash ? Have you been able to run similar
VMs on prior CURRENT releases without this issue (i.e. have we
introduced a regression) ?

  Thanks for that.

  If you see this again, would you be able to grab VM state for all the
vcpus with

bhyvectl --get-all --cpu=0 --vm=100amd64
bhyvectl --get-all --cpu=1 --vm=100amd64
bhyvectl --get-all --cpu=2 --vm=100amd64
bhyvectl --get-all --cpu=3 --vm=100amd64

later,

Peter.
