When install VM from ON (+ KVM/VMWare) i have a problem with network. I configure it with  
auto eth0 and static IP.  
After reboot /etc/network/interfaces become empty ( only loopback note)  
ifconfig -a shows me 2 interfaces.  
/var/log/kern.log | grep ens3

mail kernel: [0.916689] 8139cp 0000:00:03.0 ens3: renamed from eth0  
mail kernel: [223.168725] 8139cp 0000:00:03.0 ens3: link up, 100Mbps, full-duplex, lpa 0x05E1  
mail kernel: [0.899276] 8139cp 0000:00:03.0 ens3: renamed from eth0  
mail kernel: [103.805610] 8139cp 0000:00:03.0 ens3: link up, 100Mbps, full-duplex, lpa 0x05E1

does it problem of OpenNebula? or it’s problem of hands?

Problem was in old package of one-context. I installed last version and problem was solved
