You have been subscribed to a public bug: For a couple of days I'm trying (on and off) to launch Ubuntu 12.04 guest (32-bit) on my 10.04 KVM host (AMD CPU in 32-bit mode with PAE enabled, stock server kernel). I have tried it with different images (built with VMBuilder, downloaded from cloud-images.ubuntu.com or even the installation ISO images of different flavors). They all hang on boot, either after saying "Starting up ..." or just with a black screen. Kernel options have no effect, it seems the hang happens in GRUB, before kernel is launched. I have tried enabling debug in grub and the last lines I see about loading initrd, malloc and several reallocator.c traces, then hang.
A simple steps to reproduce: # wget http://uec-images.ubuntu.com/releases/precise/release-20120822/ubuntu-12.04-server-cloudimg-i386-disk1.img # qemu-img convert -O qcow2 ubuntu-12.04-server-cloudimg-i386-disk1.img moa.qcow2 # kvm -m 512 -smp 1 -drive file=./moa.qcow2 -vnc 127.0.0.1:10 In attached vnc client this briefly displays GRUB prompt and hangs with black screen. The same happens without image conversion step, that is # kvm -m 512 -smp 1 -drive file=./ubuntu-12.04-server-cloudimg-i386-disk1.img -vnc 127.0.0.1:10 At the same time, the host perfectly runs about 10 Lucid guests, so this should not be a host configuration problem. ** Affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment -- Ubuntu 12.04 (Precise) guests can't boot on Ubuntu 10.04 (Lucid) QEMU-KVM host https://bugs.launchpad.net/bugs/1047531 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. -- Ubuntu-server-bugs mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
