Monitoring KVM Machine Uptimes
Hey folks. Currently, I am working on an accounting-solution for Private Cloud with Eucalyptus as my bachelor-thesis. Eucalyptus bases on libvirt providing the KVM machines. Part of the thesis is kind of measurement for the uptimes of each instance in the cloud. As Eucalyptus is based on libvirt, i want to know if there is kind of tool already setup for monitoring a vm in terms of uptimes,

data monitored by "virDomainBlockStats" API not consistent with ones reading from /proc/[pid]/io, and corrugated with /proc/diskstats
Hi, all. While monitoring KVM VMs’ disk utilisation using libvirt API “virDomainBlockStats", I find that the results acquired is not consistent with the value read from /proc/[vm_pid]/io(i only care about “rd_bytes" and “wr_bytes” fields). Since libvirt doesn’t support host level monitoring, i have to calculate the host’s disk utilisation by reading from the /proc/diskstats file.

Monitoring and statistics through libvirt
Hi folks, is it possible to monitor and gather statistics in realtime (CPU, memory, HDD, network, ... - something like dstat) of guest systems with libvirt through console from host system (KVM based)? If yes, do those guests need to be created through libvirt? Thanks for your help and time.
