Has that issue been reported anywhere? Or is the infinite loop that the VM just keeps crashing and rebooting? In that case the behavior actually seems correct. (Though honestly I kind of question if we should be setting on_crash=reboot as the default anyways. I don't think it affected us with qemu much since it didn't have any sort of crash detection for a long time, but maybe we should revisit) - Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
