Bug Description

Binary package hint: grub

I'm doing QA testing on hardy images as of today, testing various images on kvm. For the Ubuntu desktop amd64 cd, and Kubuntu amd64 DVD installation both fail at grub installation, saying ""Executing 'grub-install (hd0)' failed. This is a fatal error.". This seems to be completely repeatable. Steps to repeate:

* qemu-img create -f qcow2 foo.qemu 100G
* kvm -m 1024 -hda foo.qemu -cdrom /path/to/the.iso -boot d
* install as normally

Henrik Omma tells me on IRC that he has just managed to complete an installation with Ubuntu amd64 server in KVM, so it is probably not a KVM problem.

The md5sums of the images:

84bcc78154076ca4f2306319c73c186a ubuntu/hardy-desktop-amd64.iso
20f60ad776224ac3b8fd3047ae949880 kubuntu/hardy-dvd-amd64.iso

I'll be happy to provide any logs you may require, or the entire (failed) qemu image, which is around 524 megabytes (lzma compressed).

This seems possibly related to #218112, but since that seems to have been fixed, this might be a new problem.

The actual error here is not shown in the debug file, but I expect it would be in /var/log/syslog.

I don't think it's obvious that this is the same bug as in 181812, even though they have the same symptoms. (GRUB might fail to install for several different reasons.)

Soren says that any i386 binary run from the amd64 live environment fails in the same way, which seems pretty terrible. Bumping to critical.

Also apparently just in kvm.

This turned out to be a bug in kvm's vmport implementation.

I cannot reproduce this. I just completed a succesful install of i386 desktop. Anyone else?
