Created KVM whith Server2012R2 and set it to use vmbr1. NIC is E1000. Inside assign the static IP 192.168.10.2/25

I cant see network from the guest. Also in proxmox webgui I see that eth1 not active.

What should I do?

And one more thing. If, just for experiment, I set static IP to vmbr1, and then ping it from another PC and list to show arp entries I see that both adresses have same MAC^
