Hello,
I am running Ovirt 3.6.1 on CentOS 7.1 in a single server, hosted
engine setup.
I have created 10 dummy dummy interfaces names 'dummy_[0-9]'. Ovirt
sees them, and in "Networks" for my cluster, I created 10 10
"internal" networks called 'Internal_[0-9]'.
In the "Hosts" tab, in the "Network Interfaces" tab for my host, I
assigned the 'dummy_*' interfaces tot he appropriate 'Internal_*'
network (i.e., dummy_0 -> Internal_0, dummy_1 -> Internal_1, etc.)
I have create two VMs and assigned a NIC interface on each attached to
the 'Internal_0' network. I gave the interfaces on the gusts an IP
int he same subnet, but they cannot talk to each other.
When I try to ping one from the other, here is the response I get
(public IPs redacted):
--- START ---
C:\Users\Administrator>ping 192.168.100.12
Pinging 192.168.100.12 with 32 bytes of data:
Reply from 192.168.100.20: Destination host unreachable.
Reply from XX.XXX.XX.XX: TTL expired in transit.
Request timed out.
Reply from XX.XXX.XX.XX: TTL expired in transit.
Ping statistics for 192.168.100.12:
Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),
--- END ---
The IP of the PC I am pinging from is '192.168.100.20'
I have been able to setup internal networks like this before, but seem
to be missing something and I am not sure what?
Here is what the dummy_0 interface shows when I run 'ip addr show':
--- START ---
7: dummy_0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue
master Internal_0 state UNKNOWN
link/ether 0e:a2:6b:54:1a:91 brd ff:ff:ff:ff:ff:ff
--- END ---
and Internal_0 looks like this:
--- START ---
20: Internal_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UP
link/ether 0e:a2:6b:54:1a:91 brd ff:ff:ff:ff:ff:ff
inet6 fe80::dc07:84ff:fe1b:60cb/64 scope link
valid_lft forever preferred_lft forever
--- END ---
I am not sure what other info you need, so please do let me know.
I did see this:
<http://blog.duderamos.com/internal-isolated-networks-on-ovirt/> and
except that I use 'dummy_*' instead of 'dummy*', my setup is the same.
Thanks, in advance, for your help on this.
Regards,
Alan
