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()
for id in domIds:
dom0 = conn.lookupByID(id)
try:
print "memory stats: %s"% dom0.memoryStats().values()
except:
print 'Failed to find the memory data of this domain'
sys.exit(1)
except:
print 'Failed to find the main domain'
sys.exit(1)
But this code 'dom0.memoryStats().values()' is returning empty list.I need
to collect more information regarding the memory .How should I proceed?
Regards,
Arpita
