Hello,<br>
<br>
I'm running an three node installation of opennebula with one frontend and two vm-hosts (KVM) and<br>
a fixed network configuration. The used "network file" has the content:<br>
<br>
NAME = "First Lan"<br>
TYPE = FIXED<br>
<br>
# We have to bind this network to ''virbr1'' for Internet Access<br>
BRIDGE = br0<br>
<br>
LEASES = [IP=192.168.78.115]<br>
LEASES = [IP=192.168.78.116]<br>
<br>
and sunstone shows:<br>
<br>
192.168.78.115 02:00:84:b0:4e:73 Used by VM 57<br>
192.168.78.116 02:00:84:b0:4e:74 Used by VM 62<br>
<br>
<br>
I booted two images (centos 6) and modified the /etc/sysconfig/network-<u></u>scripts/ifcfg-eth0<br>
to use dhcp with one of the two mac-adresses. After a network restart, to my surprise ifconfig -a<br>
shows in the first case the mac-address 02:00:84:b0:4e:73 with 192.168.78.118 and<br>
in the second case the mac-address 02:00:84:b0:4e:74 with 192.168.78.119.<br>
How is this possible; the mac-addresses should be unknown it the existing network.<br>
<br>
Is there an explanation for this behavior?<br>
<br>
Regards Hendrik<br>
<br>
