Subject: 2.6.27 - SMP enabled, but only 1 CPU
Date: Mon, 13 Oct 2008 17:24:41 -0400 [thread overview]
Message-ID: <48F3BC99.5040409@theshore.net> (raw)
I just compiled 2.6.27 (pae) using my .config from 2.6.26. It boots
fine, but only one CPU shows up, despite "vcpus = 4" and all of the SMP
goodness enabled. This happens on both Xen 3.2.x and 3.3.x (64 bit
hypervisor).
beefcake:2.6.27-linode14# grep SMP .config
CONFIG_X86_SMP=y
CONFIG_X86_32_SMP=y
CONFIG_USE_GENERIC_SMP_HELPERS=y
CONFIG_SMP=y
CONFIG_X86_FIND_SMP_CONFIG=y
# CONFIG_X86_VSMP is not set
CONFIG_PM_SLEEP_SMP=y
root@ubuntu:~# uname -a
Linux ubuntu 2.6.27-linode14 #1 SMP Sun Oct 12 20:34:47 EDT 2008 i686
GNU/Linux
root@ubuntu:~# cat /proc/cpuinfo
processor : 0
...
(and that's it -- just one CPU)
I must be missing something obvious, so I'd appreciate another set of
eyes on this. My .config, boot log, and xen.conf are located here:

Thanks,
-Chris
