Frequent Spice agent crashes as a KVM/Libvirt guest can be frustrating, but there are a few things to try. First, ensure that your Spice server and client are up to date to rule out bugs in the software. Additionally, check the configuration of your guest VM and ensure it has the appropriate resources allocated, such as CPU, RAM, and video memory. Sometimes, adjusting the Spice agent version or switching to a different display protocol like VNC might help. It’s also a good idea to examine the logs for any specific error messages that could point to the root cause. For more troubleshooting tips, visit https://hostever.org/.

The system starts fine and works for a time (often short, sometimes longer). However, eventually the system display halts, and after a time goes all black. Occasionally, the system might regain responsiveness, but more likely never does, and requires a restart. A soft restart is adequate, and the system responds to the queue to shutdown. The halting does not seem to be related to workload and occurs on a system running idle with adequate resources. After restarting, an error report displays saying that spice-vdagent crashed with a SIGSEV. This seems to be a recent development, but the issue has happened more occasionally in the past. However, it has become a frequent enough issue to make the experience unusable. Guest vm set up with a standard process on both Ubuntu and Fedora hosts, using default VM settings and reasonable resources allocated. Additional details below.
