For about one week, I had an Ubuntu 18.04 installation that I’ve had running for years as TrueNAS virtual machine starting to fail after a few hours of running.
This VM not working is not the end of the world, but I had been using this as a utility knife for all sorts of things, and I didn’t want to chuck it to the curb just yet.
I was seeing the following in my TrueNAS Log:
Mar 13 11:47:56 maria kernel: pid 1552 (bhyve), jid 0, uid 0: exited on signal 11 Mar 13 11:47:58 maria kernel: vnet1: link state changed to DOWN
I had to force a power down and then restart the VM. Sometimes the VM wouldn’t start at all.
After finding an ancient article about a similar issue, someone had mentioned that when they switched their virtual machine’s NIC device from Intel e82858 (e1000) to VirtIO, that was the solution.
After 48 hours, my TrueNAS Virtual Machine was running stable.
It’s difficult to say why this began. I last updated TrueNAS to 12.08-U8 on February 2nd, 2022. I first noticed the TrueNAS VM wasn’t running when I was checking my internet speed graph in Grafana starting around March 3rd. However, I have unattended upgrades for this virtual machine set, so it’s possible there was an update to the packages that caused a conflict with Intel e82858 (e1000).
Perhaps this will be helpful to you.
