pfSense vm is crashing and taking down the host as well.

  • I'm running pfSense in kvm under an ubuntu 20.04 box with a ryzen 1500x. However, it crashes very often, and often brings the host down with the vm as well, and I have to hold down the power button to force my server to restart. I have tried changing the memory, but that didn't help at all.

    Here are the logs: textdump.tar.txt, info.txt

    This is my first post here, so if I put this in the wrong place or didn't give enough information please move it/tell me.

    Thanks in advance.

    Would be more like the host is having issues/crashing and taking down the vms.. If a vm crashing would take down the host, then VMs would be utterly useless..

    Are you passing hardware directly to the VM? Like a nic or video card, usb, etc.

  • I couldn't find any crash logs on the host, so I just assumed it would be the VM. Also, when I wasn't running the pfSense VM, my host wasn't crashing. I am passing 3 out of 4 nic ports on an intel nic directly into pfsense, nothing else. Do I need to post any more logs?

    Well when you pass hardware to a vm, then yeah ok.. something going wrong with the VM could effect the host.

    There really is little point to passing the nic to the VM.. Just let the vm use a virtual nic that is bridged to the physical nic. Your not going to see any sort of performance issues doing it that way.. And allows for much better control and flexibility.

  • OK I'll try that, thanks. Just because I'm curious, how will using a virtual nic allow for more control+ flexibility?
