FreeBSD move to Proxmox , NICs sometimes can not work

[mfaridi]

I have FreeBSD physical server . this server work for me 5 years , after 5 years , mainboard is fail and sometimes it can not turn ON , So I move this server to VM by Proxmox , everything is OK and my FreeBSD boot good ,
My FreeBSD has two NIC , one NIC with public IP and one NIC with private IP.
I do not know why sometime one NIC can not work good . for example , yesterday when I try to ssh to my server by 192.168.0.210 , I can not ssh , so I ssh to server with public IP and I ssh to server by 8.8.8.210, after ssh when I run ifconfig , I see em0 do not have IP , my rc,conf is correct , after reboot everything is OK and I can shh by 192.168.0.210 and 8.8.8.210 , but today I can not shh by 8.8.8.210 , ifconfig show me em1 has IP , but I can not connect to server ,
How I can test what is problem ?

sometime I see connection time out.
when I run this command in VM FreeBSD

/etc/rc.d/netif restart

I see this

Hi,

I don't see a Proxmox problem here

Can't assign requested addressifconfig: ioctl (SIOCDIFADDR): Can't assign requested address

=> check your configuration, you assigned the address 192.168.0.19 twice in rc.conf
