troubleshooting question - VERR_DEV_IO_ERROR

Post by blc5216 »

Host = Ubuntu 22.04.02
Virtualbox = v7.0.8 with Host & Guest additions
Guest = Windows 10
Screenshots of config & runtime info are attached

I have been using this VM for several months and previously a similarly configured VM for a couple of years. This issue now occurs erratically. Sometimes immediately on startup. Sometimes after I have been using the windows application for a while. Frequently when I leave the workspace running Virtualbox to do something else and then return.

Log fragment:

00:11:06.837601 AHCI#0: Port 0 reset
00:11:06.838796 VD#0: Cancelling all active requests
00:31:22.692786 VMMDev: Guest Log: VBOXNP: DLL loaded.

00:40:09.461364 AHCI#0: Port 0 reset
00:40:09.462521 VD#0: Cancelling all active requests

Question #1: Is this telling me that the VM on SATA Port 0 can no longer be reached?

Question #2: My vdi file is not located on my primary partiion. It is accessed through a symlink on a second drive. Could this be causing the issue?

Thanks for your help!

VERR_DEV_IO_ERROR means that VirtualBox encountered a host I/O error when running the VM. For example, read errors on a host drive.
