CHR 6.49.6 to CHR 7.3.1 Failure

Sun Jul 17, 2022 3:23 am

We have a couple of virtual host running in different public data centers, the virtualization host are running Rocky Linux 8.x with KVM and the primary nic card is a 10Gbps SFP connection bridged via openvswitch between host and CHR image and presented as "ether2". Additional the virtual machines running on the host use an openvswitch internal virtual network to allow communications in-between each other and are presented to CHR via interface "ether1" which allows communications between virtual machines and outside world via CHR. CHR Images started as 6.49.2 and has been expanded to 1GB disk space and upgraded along the way to 6.49.6 where it currently stands running as designed but when I attempt to upgrade to 7.3.1 via System > Package > Check for Upgrades > Upgrade it downloads and reboots and then you suddenly get crippled CHR routing, can remote winbox to router, remote ovpn tunnels establish, but cannot connect to virtual machines nat'd through. When you jump into the virtual machine it complains about no dns resolve (pointed at CHR / Google) but you can ping and trace route the DNS server addresses. Tried changing the firewall settings over to Interface List instead of Interface's but this had no effect on correcting routing nor did Interfaces "Detect Internet". Have attempted to load CHR 7.3.1 from fresh raw image file and using the rsc file to restore settings and configuration but issue follows. Have been able to update our physical mikrotik hardware at several locations from 6.49.6 to 7.3.1 with very little issues.

Additional under interfaces either "ether1" or "ether2" show the same on 6.49.6 or 7.3.1 as Auto Negotiation=incomplete, Rate=unknown, Duplex=unchecked both are presented as Device Model = "virtio" from KVM. Will note this is causing about half throughput, virtualization host test at 10Gbps/10Gbps but anything behind CHR test between 6Gbps/6Gbps or less.
