Re: how to make checkpoint for a PV vm , while maintain it running ?

[tgh <wwwwww4187@sina.com.cn>]

hi
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?

Thanks
