Hi all, I just tried to use xenmon to monitor VMs in a Xen platform. It is strange that the io_count reported by xenmon is always zero for all the domains (including dom0). I ran network intensive as well as disk intensive I/O workloads. Xenmon reports nothing about the I/O event. The page transfer is always zero, but the page map and unmap have values. Does xen still transfer data from dom0 from/to domu for I/O request? or all the data "transfer" is based on grant table map/unmap? Best regards, Jia. FYI: xen 3.3 (PV) CentOS Linux 2.6.18-3 for dom0 and domU Intel Xeon two 4-core _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
