Suddenly I can’t create or start virtual machines. I get the following as an example of starting a already created VM:

Error starting domain: internal error: process exited while connecting to monitor: 2025-07-08T17:34:09.019664Z qemu-system-x86_64: -accel kvm: ioctl(KVM_CREATE_VM) failed: Input/output error
2025-07-08T17:34:09.019820Z qemu-system-x86_64: -accel kvm: failed to initialize kvm: Input/output error

Any suggestions?
