linux-image-virtual - No watchdog drivers enabled.

[Ian Kumlien]

In KVM there is support for two different watchdog hardwares so it can reboot the VM if the machine stops responding, this is all pretty useless when the virtual kernel lacks support for watchdogs. =)

(Tested on Lucid)

[Ian Kumlien (pomac)]

libvirtd currently lists i6300esb and ib700 as supported watchdog hardwares...

[Jeremy Foshee (jeremyfoshee)]

Hi pomac,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 642930

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Since this is a virtual machine i built it with lucid, since it's LTS, using vmbuilder.

The virtual machine was built with:
vmbuilder kvm ubuntu --suite=lucid --flavour=virtual

In the virtual machine:
lspci |grep dog
00:06.0 System peripheral: Intel Corporation 6300ESB Watchdog Timer

ls /lib/modules/`uname -r`/kernel/drivers/watchdog
softdog.ko

dmesg reports nothing wrt finding a watchdog.

And please name a text mode browser that works with the launchpad login.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Ryan Davies (ryan-professional)]

Still an issue with the 3.2.0-14-virtual kernel

Only softdog.ko in the watchdog drivers directory

[p (p1)]

lucid is still affected by this bug.

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 642930

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Ian Kumlien (pomac)]

What logfile? The issue is the kernel configuration - if you enable watchdogs for the virtual image this will not be a issue and the watchdog will be autodetected.

Logfiles are not needed.

The watchdog drivers are present in the linux-image-extra-*-virtual package. Since they are not added installed by default to virtual installed, they must be manually installed by issuing the following command in the virtual machine.

sudo apt-get install linux-image-extra-virtual

Ubuntu disables by default all watchdog devices, so once you've installed the watchdog daemon, you'll have to add your device's driver to your /etc/module

While installing linux-image-extra-virtual will work, it also eats up ~230 MB more of storage:

Do you want to continue? [Y/n]

IMHO, the watchdog devices commonly available for various hypervisors should be added to the linux-image-virtual flavor.
