Hi all.
I have to servers with ovirt.
And to identical virtual machines.
Both servers are identical. But on second virtual server not working one
network interface. Ping have a problem. I tried to change network
driver, but has no effect.
I don't understand that to do

Hi Alexander,
So if I understand it correctly, you have the following configuration:
- 2 hosts, each having 2 NICs
- 2 virtual machines, each have a connection to each one of the NICs
available on the hosts
On one of the VMs you only see 1 NIC instead of the 2?
Are you sure that the VM is properly configured to have 2 NICs?
What Linux distro and version you're using on the hosts and inside the VMs ?
Can you please send us:
- the logs from the VM, e.g. /var/log/messages
- the output of lspci -v
- the output of ip link
Thanks in advance,

Hi Lev.
On one of the VMs you only see 1 NIC instead of the 2?
NO. both VM's sees two NIC, but on first VM ping with no error, and
second VM ping with 75% error.

Hi Alex,
That is quite strange...
Does this happen on both hosts - have you tried to migrate the VM to the
second host and see if the issue still remains?
Thanks in advance,

Hi Lev.
I am create new virtual host, and run ping from internet.
Ping results 70% packet loss.
But, if i am running ping from virtual host to somebody host in the
internet and at the same time, i am pinging this virtual host from internet.
then ping results 0% packet loss or 10% packet loss.

Hi Lev.<br>
<br>
I am create new virtual host, and run ping from internet.<br>
<br>
Ping results 70% packet loss.<br>
<br>
But, if i am running ping from virtual host to somebody host in the
internet and at the same time, i am pinging this virtual host from
internet.<br>
<br>
then ping results 0% packet loss or 10% packet loss. <br>

Alexander,<br>
<br>
So if I understand it correctly, you have the
following configuration:<br>
- 2 hosts, each having 2 NICs<br>
- 2 virtual machines, each have a connection
to each one of the NICs<br>
available on the hosts<br>
<br>
On one of the VMs you only see 1 NIC instead
of the 2?<br>
<br>
Are you sure that the VM is properly
configured to have 2 NICs?<br>
<br>
What Linux distro and version you're using on
the hosts and inside the VMs ?<br>
<br>
Can you please send us:<br>
- the logs from the VM, e.g. /var/log/messages<br>
- the output of lspci -v<br>
- the output of ip link<br>
<br>
Thanks in advance,<br>

Hi Alex,
So if you're sending data out there is no or almost no data loss?
Have you tried to move the VM to the second host to see if it makes any
difference?
I actually tried to call you by phone but the call gets dropped once I
enter * and your ext. number, as the voice prompt says to.
Tried to enter the ext. number directly without *, still without success.
Thanks in advance,
