[Qemu-devel] [PATCH v4 07/07] s390: make sclp ascii console the default |
Date: |
Thu, 26 Jul 2012 10:59:46 +0200 |
This patch makes the sclp ascii default for S390. It requires a guest
kernel that autodetects the console and which not blindly assumes
that kvm means virtio console.
(commit cd1834591fe9564720ac4b0193bf1c790fe89f0d
KVM: s390: Perform early event mask processing during boot)
Otherwise the guest admin has to explicitely add console=ttyS1 to the
command line.
