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>
<br>

<div>Hi Alex,<br>
<br>
</div>
<div>That is quite strange...<br>
</div>
<div><br>
</div>
Does this happen on both hosts - have you tried to migrate the
VM to the second host and see if the issue still remains?<br>
</div>
<br>

<div>Thanks in advance,<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>
<br>
