<DIV>Hi All,</DIV>
<DIV> </DIV>
<DIV>    I installed a single-node openstack from folsom source code. When I start quantum services(quantum-server, quantum-openvswitch-agent and quantum-dhcp-agent) one by one, the host machine reboot itself. My start script is as follow:</DIV>
<DIV> ____________________________quantum_start.sh______________________________________________</DIV>
<DIV>quantum-server --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini --log-dir=/var/log/quantum --log-file=quantum-server.log &</DIV>
<DIV>quantum-openvswitch-agent --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini --log-dir=/var/log/quantum --log-file=quantum-openvswitch-agent.log &<BR>quantum-dhcp-agent --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini --log-dir=/var/log/quantum --log-file=quantum-dhcp-agent.log &</DIV>
<DIV>
<DIV>________________________________________________________________________________________</DIV>
<DIV> </DIV>
<DIV>    I split the starting script into two script, and execute the second script several minites after the first one, then the host machine does not reboot itself any more. The two scripts are as follows:</DIV>
<DIV>
<DIV>____________________________first.sh______________________________________________</DIV>
<DIV>quantum-server --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini --log-dir=/var/log/quantum --log-file=quantum-server.log &</DIV>
<DIV>________________________________________________________________________________________</DIV>
<DIV> </DIV>
<DIV>
<DIV>____________________________second.sh______________________________________________</DIV>quantum-openvswitch-agent --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/quantum/plugins/openvswitch/ovs_quantum_plugin.ini --log-dir=/var/log/quantum --log-file=quantum-openvswitch-agent.log &<BR>quantum-dhcp-agent --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini --log-dir=/var/log/quantum --log-file=quantum-dhcp-agent.log &
<DIV>________________________________________________________________________________________</DIV>
<DIV> </DIV>
<DIV>    Does anyone encounter the same case as mine?  Why I can't start quantum-server, quantum-openvswitch-agent and quantum-openvswitch-agent one by one continuously?</DIV>
