Re: [ovirt-users] Network interface not working

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. 28.05.2017 13:34, Lev Veyde пишет: 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?
