Uh-huh.  So, what key and value are you trying to write?  Does your VM
have write permissions to that part of the store?

I try to write some new key-value pairs or modify some existed key in the the DomU's xenstore tree, such as /local/domain/<DomId>/<key>. The <DomId> is the ID of the DomainU.

Maybe the VM doesn't have the permission to write its own key in Xenstore. So, how to make the VM to have the permission to write the key and value in Xenstore?

Thanks,

Bei Guan
