Hi All,

I created a VM, and installed RHEL5.3 in it, then I built and installed xenstore commands with the following steps:
# wget http://bits.xensource.com/oss-xen/release/3.0.3-0/src.tgz/xen-3.0.3_0-src.tgz
# tar xzvf xen-3.0.3_0-src.tgz
# cd xen-3.0.3_0-src/tools/libxc
# make all
# cd xen-3.0.3_0-src/tools/xenstore
# make install

When I run the following command to write something into Xenstore, I got error:
# xenstore-write vm-data/param1 value1
xenstore-write: could not write path vm-data/param1

In the hypervisor host(RHEL5.3 with Xen kernel), I found an error message in the log file of xenstored:
IN 0xd3be2d0 20091101 16:18:55 WRITE (vm-data/param1 value1)
OUT 0xd3be2d0 20091101 16:18:55 ERROR (EACCES )

Seems I can not access some node inf xentore...
Any suggestion?

Thanks and regards,
Qian
