At this time, the only files in /proc that are virtualized are
the /proc/$PID/* files for each process, and the /proc/meminfo
global file. All the other files reflect global host state.
Are there particular files in /proc/NNNN that you want to see
virtualized in the future ?
Well, I used to monitor a kvm vm by a script reading info from files such as /proc/stat,
/proc/loadavg, /proc/meminfo, /proc/diskstats, /proc/net/dev. Through those files under
/proc, I can get the whole statistic info of the vm including cpu/memory/disk/net.
If I want to do the same work in lxc supported by libvirt, How can I make it?
BTW, I know virt-top can do such things. But what I want is a programming way such as
libvirt interface.
