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?bugh6524

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 “, 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?
