Since the update to 7.4.1708, I've got one KVM host that behaves very similarly to: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686524 These guests were installed with (snipped for brevity): virt-install --name xxx --memory 2048 --vcpus 2 --location xxx --disk xxx --disk xxx --network bridge=br0 --graphics none --autostart --extra-args "console=ttyS0 ks=xxx" --rng /dev/urandom Those guests simply hang until I use "virsh console <guest>", at which time I see kernel messages immediately, so it seems like the guest's GRUB2 runs normally, but the guest kernel does not. Is anyone seeing similar problems?
