+ Amazon's EC2 is a xen based cloud platform, the bootloader that is used is
'pvgrub'. pvgrub runs inside a xen instance, reads a /boot/grub/menu.lst file,
and loads the kernels specified there. It does not support grub2 style
configuration (/boot/grub/grub.cfg). Thus, we have installed inside

+ whitelist metrics. Those previously required a kernel to end in
+ '-virtual'.
+
+ In the development cycle of 12.10, the -virtual kernel went away. It is

+

kernels will be named in the newer fashion, and will end in '-generic', rather
than '-virtual'. As a result, grub-legacy-ec2's whitelist will not write

+ The biggest potential for regression would be in writing an entry to
/boot/grub/menu.lst for a kernel that would not boot. There is protection
against this in the included patch by checking the version number as well as
the name.

[Bug 1005551] Re: update-grub-legacy-ec2 ignores kernels named -generic
Hello Ben, or anyone else affected, Accepted cloud-init into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/cloud- init/0.6.3-0ubuntu1.5 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

[Impact]
- In 12.04, it is now supported to run a 12.10 backports kernel. These new

As a result, grub-legacy-ec2's whitelist will not write entries for these

The end result is that the user who installs these kernels will not be

[Bug 1005551] Re: update-grub-legacy-ec2 ignores kernels named -generic
Hello Ben, or anyone else affected, Accepted cloud-init into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/cloud- init/0.6.3-0ubuntu1.5 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance! ** Changed in: cloud-init (Ubuntu Precise) Status: Confirmed = Fix Committed ** Tags added: verification-needed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005551 Title: update-grub-legacy-ec2 ignores kernels named -generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1005551/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1005551] Re: update-grub-legacy-ec2 ignores kernels named -generic
** Description changed:
== Begin SRU Information ==
[General Description]
Amazon's EC2 is a xen based cloud platform, the bootloader that is used is
'pvgrub'. pvgrub runs inside a xen instance, reads a /boot/grub/menu.lst file,
and loads the kernels specified there. It does not support grub2 style
configuration (/boot/grub/grub.cfg). Thus, we have installed inside
cloud-images, a package named 'grub-legacy-ec2' that maintains
/boot/grub/menu.lst.
grub-legacy-ec2 does not simply assume all kernels are candidates for
inclusion in /boot/grub/menu.lst. Instead, it has some very basic
whitelist metrics. Those previously required a kernel to end in
'-virtual'.
In the development cycle of 12.10, the -virtual kernel went away. It is
now simply a -generic kernel with a subset of modules.
[Impact]
- In 12.04, it is now supported to run a 12.10 backports kernel. These new
kernels will be named in the newer fashion, and will end in '-generic', rather
than '-virtual'. As a result, grub-legacy-ec2's whitelist will not write
entries for these kernels to /boot/grub/menu.lst.
+ In 12.04, it is now supported to run a 12.10 enablement kernel
(https://wiki.ubuntu.com/Kernel/LTSEnablementStack). These new kernels will be
named in the newer fashion, and will end in '-generic', rather than '-virtual'.
As a result, grub-legacy-ec2's whitelist will not write entries for these
kernels to /boot/grub/menu.lst.
The end result is that the user who installs these kernels will not be
able to easily boot them on EC2 (or other xen guest).
[Test Case]
- * Boot a cloud instance or cloud image
- * install a backports kernel
- * verify that kernel new kernel is included in /boot/grub/menu.lst
-Previously the kernel would not be included there.
+ * Boot a cloud instance or cloud image
+The daily build of a EC2 AMI id at
http://cloud-images.ubuntu.com/server/precise/current/ is fine.
+ * install a backports kernel
+sudo apt-get install linux-generic-lts-quantal
+ * verify that kernel new kernel is included in /boot/grub/menu.lst
+ Previously the kernel would not be included there.
+Previously:
+$ grep 3.5.[0-9] /boot/grub/menu.lst || echo NOT_FOUND
+NOT_FOUND
+
+But with new update-grub, it will be.
+# enable proposed
+$ echo deb http://archive.ubuntu.com/ubuntu precise-proposed main |
+ sudo tee /etc/apt/sources.list.d/proposed.list
+$ sudo apt-get update
+$ sudo apt-get install grub-legacy-ec2
+$ sudo update-grub-legacy-ec2
+$ grep 3.5.[0-9] /boot/grub/menu.lst || echo NOT_FOUND
+titleUbuntu 12.04.2 LTS, kernel 3.5.0-24-generic
+kernel /boot/vmlinuz-3.5.0-24-generic root=LABEL=cloudimg-rootfs ro
console=hvc0
+...
[Regression Potential]
The biggest potential for regression would be in writing an entry to
/boot/grub/menu.lst for a kernel that would not boot. There is protection
against this in the included patch by checking the version number as well as
the name.
That amounts to:
- dpkg --compare-versions ${ver_flavor%-generic} ge 3.4.0-3 return 0;;
+ dpkg --compare-versions ${ver_flavor%-generic} ge 3.4.0-3 return 0;;
where 'ver_flavor' is the version as found in the file name of the kernel
(ie, /boot/vmlinux-2.6.35-13-generic).
== End SRU Information ==
Quantal stopped booting on EC2 around 2012-05-25.
