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,

Hi all.
I have to servers with ovirt.
