Hi All,

I want to know how to write a new key-value or modify a exsited key-value in xenstore. When using xb_write() with message type XS_WRITE or XS_SET_PERMS, I always get the error EACCES. I have seen the XenBus xenwiki page. However, I am still a little confusing about how to write to xenstore for a DomU when using Xenbus. Thank you very much.

Best Regards,

Bei Guan
