[Bug 880049] Re: 100% CPU usage in init if /dev/console is not available
I would like to add something to the opinion that openvz should fix this. I agree that it should be fixed by openvz. But many people are not in control of the openvz/ Virtuozzo installation, because they just have rent a virtual server. And as it worked before it should still work because else those affected people don't trust into the dependability of Ubuntu any more. And by the way, there are many fixes for bad hardware in the kernel, why shouldn't there be fixes in Ubuntu for bad virtual hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880049 Title: 100% CPU usage in init if /dev/console is not available To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/880049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I would consider this a regression - it was working fine in Natty, so has been broken for oneiric.

Re: [Bug 880049] Re: 100% CPU usage in init if /dev/console is not available
@Ajunne Unfortunately that doesn't work for me. After granting access to /dev/console to the VE (and rebooting it), I get "No such device" instead of "Operation not permitted" when trying to access the device and init still hogs the cpu. Maybe it is a problem with the host (Debian 6.0, linux-image-2.6.32-5-openvz-686 = 2.6.32-31) ?

I have the same issue here, physical server runs CentOS 6.0, VE runs Ubuntu. You can easily grant access to the physical version of /dev/console with the following command on your physical server: vzctl set 105 --devices c:5:1:rw --save Replace 105 with the number of you VE.

[Bug 880049] Re: 100% CPU usage in init if /dev/console is not available
I totally agree the proper fix would be that OpenVZ provides a /dev/console. My patch is rather a workaround. Concerning jobs specifying console access, they already fallback to CONSOLE_NONE in job_process_spawn so they are working (maybe not exactly with the same behaviour though). Concerning jobs specifying console ownership, they will fail indeed, but those jobs (rcS, mountall-shell, ...) really can't be used in a OpenVZ environment anyway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880049 Title: 100% CPU usage in init if /dev/console is not available To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/880049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 880049] Re: 100% CPU usage in init if /dev/console is not available
Thanks for reporting this issue. However, the console device is a device
expected to exist on all Linux systems. The problem here is that Upstart
*needs* access to the console: if it has no console access, jobs would
behave differently in an OpenVZ container to running outside a container
(bad). The patch above will not help jobs that have specified they want
console access or ownership ("console output" or "console owner").
I am not an OpenVZ expert, but I do feel that the "fix" for this issue
is for the OpenVZ environment to provide a /dev/console that Upstart is
able to use such as would be provided by other virtualization
technologies (LXC, qemu/kvm, Xen, VirtualBox) otherwise Upstart cannot
guarantee job behaviour.
