I downloaded ubuntu 12.04 i386 desktop, installed it with default options, and tried there. After setting timeout=10 (from timeout=0) in /boot/grub/grub.cfg, I can see the difference between current qemu-kvm 1.1 and previous versions. Marking the bugreport as confirmed, will work out from there. Thanks! /mjt -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Removing the network opts made no difference, neither did changing the boot drive to ide-hd instead of virtio, but disabling the irqchip did (setting virtio-blk-pci.ioeventfd=off didn't make any difference for this issue). -- Jamie Heilman http://audible.transient.net/~jamie/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#683096: no grub menu before boot
I suspect this is very much related to 680719 (upstream 1021649). If you disable the in-kernel irqchip, I bet you'll get your grub menu back. I experimented some with my guests that use -display sdl and the difference is quite noticable. For example, with an ubuntu server instance that has a grub timeout of 2 seconds, using kvm -machine accel=kvm,kernel_irqchip=on ... the grub menu flickers past without any delay on my workstation, but if use -machine accel=kvm,kernel_irqchip=off the 2 second countdown timer and grub menu behave as expected. Marc, you'll want to review the above mentioned bugs and verify that your config matches; iow, that you're using a virtio-blk boot device. -- Jamie Heilman http://audible.transient.net/~jamie/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Actually, I can reproduce this on guests without any virtio devices present, the in-kernel irqchip implementation itself appears to be the source of the problem, but its likely not the same issue I thought it was. -- Jamie Heilman http://audible.transient.net/~jamie/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#683096: no grub menu before boot
Package: qemu-kvm Version: 1.1.0+dfsg-3 Severity: normal Booting a Linux VM inside KVM (using virt-manager, libvirt, qemu-kvm 1.1.0 from unstable) does not show the grub boot menu at all. It just immediatly boots and runs fine then. Downgrading qemu-kvm fo 1.0+dfsg-11 from testing made the grub-menu reappear. Is that user error, or a bug in qemu-kvm?
