To clarify, the fixes tested only fix the cloud-init piece. Since the
cloud-init module in question only runs at first boot. So while the
patch does address the problem, it only fixes it for future instances.
Existing instances that upgrade grub will be broken. Meaning that if a
ABI changes takes place in 14.04, this bug will also affect 14.04.
We need to come up a fix for existing instances as well.
** Description changed:
+ Cloud-init, as part of the first boot configures grub-pc to set the
+ device that grub should install to. However, in the case of HVM
+ instances, /dev/xvda and /dev/xvda1 are not considered (only sda, sda1,
+ vda and vda1). Since AWS HVM instances and Xen use /dev/xvdX devices,
+ this means that any Grub update with an ABI change will break the
+ instances, rendering them unable to boot.

+ ----ORIGINAL report----

It looks like a recent update to grub or the kernel on 12.04 is breaking
- unattended installs on EC2 for HVM instances.
+ unattended installs on EC2 for HVM instances.
You can reproduce the problem by doing the following:
region: us-east-1
virtualization type: HVM (e.g. r3.xlarge)
AMI ID: ami-7a916212
dpkg --configure –a
apt-get update
apt-get install -y ruby ruby-dev libicu-dev libssl-dev libxslt-dev
libxml2-dev monit
apt-get dist-upgrade –y
