Hey List, I have a DELL r200 server which I am using as a kvm hypervisor with Xenial for quite some time. It worked fine but then today I tested an upgrade for the whole server including the kernel. The last kernel was: Linux kvm3 4.4.0-64-generic #85-Ubuntu SMP Mon Feb 20 11:50:30 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
And worked fine for quite some time. The latest Xenial kernel from the upgrade (4.4.0-66-generic) causes a very specific issue. VM's with virtio nic cannot contact the network.(e1000 works fine) I have not delved to see if tcpdump sees the packets or something similar in the hypervisor level and bumped the kernel to 4.6 which I have tested long ago to work fine. Where do I file the bug report? I am pretty sure it's a very series bug but not sure who should be aware of it and how to debug if it's a machine local one or a wider issue.
