Re: [ovirt-users] Network interface not working

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 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, 2017-05-18 12:19 GMT+03:00 Герасимов Александр <gerasimov.ay at eksmo.ru>: > Hi all. > > I have to servers with ovirt. > > And to identical virtual machines. > > Both servers are identical.
