利用vSphere调整各台虚拟机后，重新启动mesos，让其启动docker，并为每个container分配cpu和mem，但每次都有一个TASK_LOST.
查看mesos slave的log，发现下面的error:
WARNING: Your kernel does not support swap limit capabilities. Limitation discarded.
解决办法:
1. Log into Ubuntu as a user with sudo privileges. 2. Edit the /etc/default/grub file. 3. Set the GRUB_CMDLINE_LINUX value as follows: GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1" 4. Save and close the file. 5. Update GRUB. $ sudo update-grub 6. Reboot your system.
