...ve some trouble with the virsh to get vm mem-usage in guest os.

Hi , I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information.I like to print memory stat of the VM like SWAP_IN , SWAP_OUT,free memory, mem cached etc.So, the code, I have written for this, is : #!/usr/local/bin/python import libvirt import sys conn = libvirt.openReadOnly(None) if conn == None: print "Failed to open connection to the hypervisor" sys.exit(1) try: domIds = conn.listDomainsID()...

Everything works. # virsh dommemstat vm1 actual 1048576 swap_in 0 swap_out 0 major_fault 751 minor_fault 3958627 unused 375900 available 1017988 rss 978248 I don't know the reason it doesn't work with ELRepo 3.10.45 kernel but I'd really like to.

E.g. the windows virtio driver supports these stats: SWAP_IN 0 /* Amount of memory swapped in */ SWAP_OUT 1 /* Amount of memory swapped out */ MAJFLT 2 /* Number of major faults */ MINFLT 3 /* Number of minor faults */ MEMFREE 4 /* Total amount of free memory */ MEMTOT 5 /* Total amount of memory */ See https://github.com/YanVugenfirer/kvm-guest-drivers-windows/blob/9a5cb6749d68bad8c3...

Hello, I'm trying to get memory usage statistic inside a guest machine using virDomainMemoryStats function at libvirt. According to http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatTags the structure could have a lot of useful memory statistic but the amount of parameters depends on the hypervisor and the driver. However using KVM I'm able to get
