Hello,
we'd like to ask you to help us solve following problem.
We have a virtual environment Proxmox ver. 5.3-11 put on a physical server.
There are 2 virtual machines working on Proxmox : both Windows Server 2012 R2 Standard. Both of the servers are using a virtual network interface card (NIC) Intel PRO/1000 MT Network Connection. There is a Microsoft driver ver.8.5.13.0 from 23.3.2010 used on
these NICs.
The problem is that one of the network interface cards gets "frozen" sometimes. It seems from the Windows Server that NIC is working fine but there are no data passing through it and system does not communicate with the LAN. The problem will gone
after the software restart of the NIC (disable / enable) but it recurs after some time - irregularly.
We have tried to change the type of the virtual Proxmox simulated NIC to following types : Realtek RTL8139, VirtIO (paravirtualized) and VMware vmxnet3 - no effect. Problem still comes back.
Thank you very much for the solution.
Dobrý deň,
Chcem Vás poprosiť o pomoc s riešením nasledovného problému.Na fyzickom serveri máme nasadené virtuálne prostredie Proxmox ver. 5.3-11. Na Proxmoxe bežia 2 virtuálne stroje: Obidva Windows Server 2012 R2 Standard. Obidva používajú virtuálnu sieťovú kartu NIC Intel PRO/1000 MT. Použitý ovládač je Microsoft verzia 8.5.13.0 z 23.3.2010.
Problém je, že jedna z NIC občas zamrzne. Z prostredia Windows sa zdá, že karta pracuje, ale netečú ňou dáta a server nekomunikuje s okolitou LAN. Problém sa odstráni softwarovým reštartom NIC (disable / enable), ale po istom čase sa problém opakuje.
Skúšali sme tiež zmeniť typ virtuálnej NIC, ale bez úspechu.
Vopred ďakujeme za riešenie problému.
