This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- precise' to 'verification-done-precise'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] A minimal fix for this bug can be found here: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3dcf63677d4eb7fdfc13290c8558c301d2588fe8 This allows the ballooning to be cancelled if adding new memory failed which means that the error message is printed once instead of repeatedly. There should still be effort to root cause this issue and determine how to avoid the ballooning errors in the first place. I still think this patch should be applied to alleviate symptoms until root cause is discovered. -- Xen balloon errors on HVM instances on EC2 (Xen 4.2.amazon): ubuntu@ip-10-63-20-99:~$ uname -a Linux ip-10-63-20-99 3.13.0-23-generic #45-Ubuntu SMP Fri Apr 4 06:58:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux ubuntu@ip-10-63-20-99:~$ dmesg |grep xen [ 0.000000] xen:events: Xen HVM callback vector for event delivery is enabled [ 0.494613] xen:balloon: Initialising balloon driver [ 0.496046] xen_balloon: Initialising balloon driver [ 0.500077] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 0.541047] Switched to clocksource xen [ 0.562579] xen: --> pirq=16 -> irq=8 (gsi=8) [ 0.562622] xen: --> pirq=17 -> irq=12 (gsi=12) [ 0.562649] xen: --> pirq=18 -> irq=1 (gsi=1) [ 0.562673] xen: --> pirq=19 -> irq=6 (gsi=6) [ 0.562705] xen: --> pirq=20 -> irq=4 (gsi=4) [ 0.920527] xen: --> pirq=21 -> irq=47 (gsi=47) [ 0.920596] xen:grant_table: Grant tables using version 1 layout [ 1.029661] xen_netfront: Initialising Xen virtual ethernet driver [ 1.236083] xenbus_probe_frontend: Device with no driver: device/vfb/0 [ 2.516067] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 6.533941] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 14.560075] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 30.592064] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 62.688153] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 94.752164] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 126.816161] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 158.880084] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 190.944069] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 223.008141] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 255.072112] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 287.136190] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 319.200053] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 351.264164] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 383.328080] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 415.392077] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 447.456112] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 479.520128] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 511.584110] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 543.648181] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 575.712070] xen:balloon: reserve_additional_memory: add_memory() failed: -17 [ 607.776178] xen:balloon: reserve_additional_memory: add_memory() failed: -17 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1304001/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
