<div dir="ltr">hi, <div><br></div><div>I installed OpenNebula 4.2 to 4 host node and 1 front-end node.</div><div><br></div><div>I have public network(1G) and private network(10G mellanox connectX3).</div><div><br></div><div>
until now, create? good. another instruction? good.(except live-migration) ssh access? good.( but it is waiting few second to access.)</div><div><br></div><div>when I use only public network in VM, pinging is greate.(anywhere success)</div>
<div><br></div><div>but when I use private network, (<a href="http://172.16.0.0/16">172.16.0.0/16</a>, no gateway, just broadcast)</div><div><br></div><div>host --> VM = ok</div><div>VM --> VM and host = can`t ping</div>
<div><br></div><div>I found VM can`t make arp table. if I manually insert ip and MAC address, I can pinging.</div><div><br></div><div>I tried KVM setting, tls listen =0, not effect.</div><div>I tried C class netmask, not effect.</div>
<div>I tried OpenVswitch, not effect.</div><div><br></div><div><b>I tried in openstack kernel. success. </b></div><div><b># yum install <a href="http://rdo.fedorapeople.org/openstack-grizzly/rdo-release-grizzly.rpm">http://rdo.fedorapeople.org/openstack-grizzly/rdo-release-grizzly.rpm</a></b></div>
<div><b># yum install -y kernel</b></div><div><b># reboot</b></div><div><b><br></b></div><div><b>and </b></div><div><b># insert 10G driver.</b></div><div><br></div><div><b>should I use openstack kernel??? I think that OpenNebula can`t support mellanox 10G ethernet.</b></div>
<div><b><br></b></div><div><b>how do I solve the problem without using openstack kernel??</b></div><div><br></div><div>another config is default.</div><div><br></div><div><br></div><div>thanks for my little English.</div>
