Emulab FAQ: Testbed Operations: Understanding FreeBSD Kernels on Disk Images

Emulab FAQ: Testbed Operations: Understanding FreeBSD Kernels on Disk Images

  • kernel.100HZ == the default kernel with 100Hz clock.
  • kernel.1000HZ == kernel.linkdelay == general kernel with higher res clock.
  • kernel.10000HZ == kernel.delay == special kernel for delay nodes.
  • kernel.jail == 1000HZ kernel with virtual node hacks.
  • kernel.save == last kernel run (created by us when booting one of the others).
  • kernel == copy of kernel that booted (created by us at boot time).

Obviously, we need to reduce the number of kernels. It's on the TODO list!
