Subject: PR KVM and TM issues
Date: Mon, 4 Apr 2016 16:44:57 +1000 [thread overview]
Message-ID: <20160404164457.539a55f0@kryten> (raw)
Hi,
I can't get an Ubuntu Wily guest to boot on an Ubuntu Wily host in PR KVM
mode. The kernel in both cases is 4.2. To reproduce:
wget -N https://cloud-images.ubuntu.com/wily/current/wily-server-cloudimg-ppc64el-disk1.img
qemu-system-ppc64 -cpu POWER8 -enable-kvm -machine pseries,kvm-type=PR -m 4G -nographic -vga none -drive file=wily-server-cloudimg-ppc64el-disk1.img,if=virtio
Should TM work inside a PR KVM guest?
Anton
