NIC card/VM Stop working

James Richmond · Jan 22, 2019

I am not to sure what all information will be needed to help me resolve this issue so please ask and I will provide it.

Here is what is going on.

We have 3 node cluster on 3 R710 servers. All 3 servers have the same hardware with a total of 8 network ports. 4 ports on the motherboard and a 4 port intel NIC.

If I have any VM's that use any port on that Intel NIC then I cannot access that VM through the web gui. I can access it through the proxmox console. I good example is I have a test VM that is running Pfsense. I can tell it to use two virtual ports that are using the built in NIC of the R710 but if I switch just one port like the WAN port of pfsense to the intel NIC then I can no longer access it at all through the web gui (can still get to it through proxmox gui) till I remove that port. Now oddly enough this happens on all 3 servers. All 3 intel network cards are acting that way.

The only fix seems to wait a week or two (found that out by accident) or reboot all the nodes. Then that intel NIC will work again.

Please any advice would be great. Again I don't know what logs to provide as I don't see any issues anywhere. If you tell me what to provide I would be more than happy to.

Thanks again!

Still having the issue. Please someone!!!

Please post the VM config.
Also what do you mean by "using the Intel NIC" - do you have a vmbr for each intel-NIC or do you try to do PCI-passthrough?

* the output of the network-configuration on the node `ip addr`, `ip link`, `ip route` would be helpful, as well as the output of the network configuration from inside the guest `ifconfig`, `route -n` for FreeBSD/pfsense

When I am having the issue of not being able to get to the VM gui via vmbr2 I will switch the LAN to use vmbr0 and then change vmbr3 to vmbr0 as well to get it off that 4 port NIC card. Also when using that NIC card I can migrate that VM to any 1 of the 3 servers and it will not work. I have a 4 port intel NIC installed in all 3 servers.

I use vmbr's and not PCI-passthrough. Here is the config for the VM:

It does.

Took a screenshot but it wont upload.

James Richmond · Jan 29, 2019

There we go.

gotuser32 · Jan 29, 2019

on mine the gui said one thing and the command line said some of the gui info but not the check boxes.
Sorry I am not much help I am very new- not a networking guy by trade now if you got a laser I can help you out LOL

Please post the VM config.
Also what do you mean by "using the Intel NIC" - do you have a vmbr for each intel-NIC or do you try to do PCI-passthrough?

* the output of the network-configuration on the node `ip addr`, `ip link`, `ip route` would be helpful, as well as the output of the network configuration from inside the guest `ifconfig`, `route -n` for FreeBSD/pfsense

Do you need any other information Stoiko?

Stoiko Ivanov · Feb 5, 2019

Please use `code` tags for config-files - otherwise it's really hard to get a decent overview.

While it may be unrelated to the current issue - you're using the same network-prefix (192.168.0.0/24) for two interfaces on each server - this does not work (without quite a bit of manual configuration) - please use one network per interface.

Can you ping the PVE-node from the guest (on the interface - 192.168.0.143) - can you ping other PVE-nodes on that interface (this is only reliable after you used each network only once

I will remove the 143,140, 146 from the server. I added them just to see if it would resolve the issue. With that said I could get to the Proxmox with those IP's even though I was not using them. What about CoroSync and Ceph? I have them on a isolated switch from the rest of the network... but both are on the same switch. I don't seem to have any issues with the cluster or any VM that does not use that 4 port NIC. And when I do use that NIC the VM seems fine besides you can't reach it unless you use console with proxmox.

I do see this sometimes but it seems to fix itself. Could this be causing issues?

The clockskew is an issue that needs to be treated (by using the same NTP-server for all your clusternodes, and by using an NTP-Server that is close to them and reliable) - but should be unrelated to the inability of a guest to ping the outside world.

try checking where the packet does not get forwarded after migration - by using tcpdump
`tcpdump -envi vmbr0 icmp1` - to see all packets on interface vmbr0 which are icmp - check the manpage of tcpdump for further infos.

Hope this helps,
