one of my VMs quit working

Post by n8dagr8 »

I have an ubuntu host running 3 virtual machines. One of these quit responding. In trying to reboot it, vboxmanage list running vms says it is running, but i cannot get to the VM via ssh or vrde. I also cannot ping the vm which is configured with a static ip address. Any ideas on how to recover? Log file attached.

Unfortunately the provided log is almost useless. You need to close down the VM before copying out the files that it was writing. Then zip the log before attaching here.

A couple of things I can see right at the start of the log.
  1. The Extension Pack version is wrong. EP versions must match the host software.
  2. Reduce the CPU allocation to 2 cores. Your 4 core host obviously can't afford 4 cores for a VM.

I do remember seeing virtualbox update during an update and I didn't think to update the EP (manually). I have updated the Expansion Pack to match and Updated the number of COR to 2. These did not resolve the issues. My other VMs will all still boot.

I booted the VM and tried multiple times to access via SSH and VRDE - no luck. No response to a ping. I tried to shutdown using vboxmanage controlvm "vmname" acpipowerbutton. That said, vbox is still showing it as running.

I uploaded a few of the log files.

In the VM configuration, I'd suggest to change Display > Screen > Graphics Adapter to VMSVGA and Display > Remote Display > Authentication Method to Null.
