Hello
Thank you for your answers.
i tried everything from the beginning with the same probleme, i can ping my Centos7 Server but i cannot not have internet access neither to my GW on the created vm by hosted-engine --deploy. i can ONLY ping my centos 7 server
I have one Centos7 server installed and updated
1 NIC eth0 at 192.168.42.114/24 But you wrote below that you have also eth1 ?
i have no more eth1 because i reinstall everything from the beginning with no eth1. ust once NIC eth0
i installed the ovirt repo
i run hosted-engine, follow the questions, i set bridge at eth0 and set the FQDN of the vm at hevm.lab.lan (which is present in the /etc/hosts file of my Centos7 server with ip 192.168.42.116)
i can see on my Centos7 Server that i have a new interface named ovirtmgmgt with the the ip previously set for eth0 and now eth0 has no ip address but i can still ssh to my centos7 serverthrough ovirtmgmt interface i presume... Indeed - this is a normal linux bridge
here is my bridge conf of my centos7 server
#brctl show bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no ovirtmgmt 8000.000c29de8495 no eth0
Once my VM is created (hevm.lab.lan), i connect to it again through vnc and i set an ip address manualy like: # ifconfig eth0 192.168.42.116/24 # route add default gw 192.168.42.254
to resume, i can only ping my centos7 server and no other host on the same subnet and no internet access.
I assume you can only ping the address of the ovirtmgmt bridge (192.168.42.114).
Right
Can you ping the address of eth1?
i have no eth1
i hope i explained my problemin a maner that you could help me.
Still not enough details.
Where are eth0 and eth1 connected?
i have a GW @192.168.42.254 my centosServer7 @192.168.42.114 (eth0) my CentosServer7-2 @192.168.42.115 (eth0) for the clustering but no yet configured.....i will set it up after i have installed the hosted-engine vm nothing more
Please provide the details I asked for below. Thanks!
Best regards,
sorry for my english
thank you for the help.

Hie.
i've been asked to email you instead of asking on the #ovirt channel. That's fine, but usually in such cases people are supposed/advised to email users@ovirt.org, Ccing specific people if needed/relevant :-)
i have followed this instructions: http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/
the only differences are the IP addresse/mapping names of the begining
_once i have installed the hosted engine through hosted-engine --deploy, i connect to it using vnc but i cannot have internet access to install the engine from ovirt repo neither ping my Main host_
i have:
192.168.42.116 virt1 virt1.lab.lan nfsmount nfsmount.lab.lan 192.168.42.117 hevm hevm.lab.lan # this is the ip i would like to set for the hosted engine VM You mean, you have this in /etc/hosts of all relevant machines?
on my Main Host cento7, i have
eth1-> 192.168.42.116 (managment NIC for ssh access and nfs server) eth0-> with nothing ovirtmgmt-> 192.168.42.114 Which includes eth0? What's the output of 'brctl show'?
Are eth0 and eth1 on the same switch/segment?
What's the subnet of each?
bond0-> with nothing That's normal
can you please help me? What do you have on the engine VM?
Can you ssh to the engine from the host? Or the other direction?
Please check both addresses of the host.
I am not sure, but for the engine VM to access 192.168.42.116, you might need to add some routing somewhere.
I'd say this isn't related to hosted-engine, but some general networking issue. If you fail to diagnose this at this point, you can try to simply boot some live cd in a VM (e.g. using virt-install or even qemu directly) and debug from there. Once you have it working, start hosted-engine again.
Please check (or post, if you want us to help) all relevant information, including the above, and also things such as:
Routing table of host/vm, and of all relevant routers
Do you use dhcp? Does it work? On host/engine?
Did you enable ip forwarding on the host (cat /proc/sys/net/ipv4/ip_forward)?
After you try ssh/ping, arp table on host/engine (arp -an)
Check iptables config/logs
Etc.
Good luck.
If you fail to solve this yourself, please Cc users@ with your reply.
Thanks!
Best,
