So today I wake up and notice nothing on my network is responding. After finding out that all my virtual machines are not responding I see this.
While I try to fix issues myself, this is something I've never seen (well just once before) and am having a hard time even knowing where to start with this.
I've rebooted the host and machines are up again. But this happened once a couple of weeks ago already and I'm afraid it's not something I can just reboot and forget about it, hoping it doesn't happen again.
Any help would be appreciated.
