Hi all,
For context; we have an 8-node cluster (4 each in 2 separate physical locations). We've recently been running into some issues when live migrating some of our VMs. Specifically yesterday when updating our nodes one by one, we need to empty them out by migrating all VMs to another node since these VMs need to stay online.
After migrating we had some network issues with the VMs in question seemingly not having any connection. In some cases removing and re-adding the network adapter did the trick but in others it did not. After some troubleshooting it seems as if only VM's which have NLB enabled (like our webservers and RDP servers) are affected by this.
So in short, is it a know issue where live migrating VMs that have NLB causes network connection issues? The only real similar post I could find is https://forum.proxmox.com/threads/win2003-multicast-nlb-not-working-after-migration.14199/ which isnt really helpful.
Thanks in advance!
