Hey all. We are having some strange guest network issues. The guest is CentOS7 running kernel "3.10.0-229.1.2.el7.x86_64". The hosts are setup with bridged networking. At random times the guest looses all network connectivity. The host is completely fine and has no issues. This is happening on both of our hosts so it rules out a hardware issue. The guest is using the virtio network driver. I just switched it to e1000 to see if it would prevent the issue.
The only way to get networking back, is to completely shutdown the guest. A reboot does not work, the guest has to be completely shut down then started again for networking to come back. Looking for some input. I have dug through logs on both the guest and host with nothing out of the ordinary.
I also updated both host nodes to the latest packages/kernel this morning and the issue happened again.
Not sure what else the issue could be, hoping someone can shed some insight or suggestions.
