Ohh, ok, it isn't a great problem (i use KVM VM).
Many thanks for the clarification.

And please let me to do a question:
Is the same for conatiners (LCX or OpenVZ)?

Many thanks for the prompt reply,
and please let me to do a question:

I have a PVE cluster, only two servers of them has NICs of 10 Gb/s for:
- LAN communication
- PVE Cluster
- LAN for VMs
(other NICs are used for DRBD and backups)

Also configurated in LACP mode (2 ports in each server)

The rest of servers has NICs of 1 Gb/s. (LACP mode, 2 ports in each server) 
for:
- LAN communication
- PVE Cluster
- LAN for VMs
(other NICs are used for DRBD and backups)

The question:
Do i have this problem?
