Hopefully someone else on the list can chime in about that. > 2. what's the best list to report the issue to? - Qemu, libvirt? No, probably the best place is on the illumos kvm related bug trackers. I can't say that I'll personally have a lot of time to dig into this for a while. But here are a few things to start with when the guest appears to freeze: First run `kvmstat 1`. That'll let us know whether there is activity going on inside the guest or not and will direct a lot of the rest of the investigation. If that shows up as basically all zeros then the next things to go run are pstack on the qemu and given the process, run the following in mdb -k: 0t<pid>::walk thread | ::findstack -v Robert ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
