Could you follow the link(https://cwiki.apache.org/CLOUDSTACK/kvm-agent-debug.html): Which KVM host os is using? Centos 6.2, 6,1, Ubuntu 10.04? Which version of libvirt is using, "virsh --version" turn the agent log level to debug: sed -i 's/INFO/DEBUG/g' /etc/cloud/agent/log4j-cloud.xml
Then reproduce the issue, and take a look at agent.log. > -----Original Message----- > From: Boylan, James [mailto:james.boy...@orbitz.com] > Sent: Tuesday, November 20, 2012 8:30 AM > To:
