[libvirt-users] Host information from libvirt KVM/Xen

[Parakkal, Navin S]

Hi,
   Is this not supported for Xen ?  I get something like the below for Xen+ssh .

libvir: error : this function is not supported by the connection driver: virNodeGetCPUStats
libvir: error : this function is not supported by the connection driver: virNodeGetMemoryStats

Regards,
Navin

[no need to mail both libvir-list and libvirt-users; the former is more for development efforts, and since this is a usage question, it is sufficient to mail just libvirt-users]

You want to use the virNodeGetCPUStats() and virNodeGetMemoryStats() APIs.  In virsh, these are wrapped under 'nodecpustats' and 'nodememstats'.
