Re: [Xen-devel] how to make checkpoint for a PV vm , while maintain it running ?

Thank your for your advise
that is to say , xen-3.1.0 does not support checkpoint while maintaining PV vm running ,is it ?or maybe ,there are something I have missed beforing checkpointing on xen-3.1.0, for the node is shared by some fellows at present, i guess I will try xen-3.1.1 later, but how to deal with it on xen-3.1.0 anyway ? or it could not on xen-3.1.0?

I've just tried this on Xen 3.1.2 and it seems to work fine. So I'd suggest 
upgrading Xen, and then if you still have problems, build xen with debug=y 
and see if anything turns up in xend.log or /var/log/daemon or the guest
