I try "virsh dommemstat <domain>" and it returns as follows

:Failed to get memory statistics for domain vm_unfw

:this function is not supported by the connection driver: virDomainMemoryStats

 

So what may be the problem?

 

I'm using CentOS release 5.5. Updated it's libvirt from 0.6.3 to 0.8.4 through "./configure; make; make install" procedure, and ran "autobuild.sh" in the directory of libvirt-0.8.4.

 

Using "virsh version", it tells xen api version is 3.0.1, and xm version is 3.3.0

 

Thanks!
