Re: [Xen-users] Make both CPUs available to Dom0

thanks joe, but - nope, checked that (it's also in my initial mail).
The value remains unchanged as '0', which according to the comments
in this file means that all cpus will be used.
does your dom0 kernel config have CONFIG_SMP=y?
try 'sudo xm dmesg | grep CPU'
if you can run domU's on different cpu's, the dom0 must be able to see
more than one.
joe
it must have CONFIG_SMP set since it worked initially until I started
messing with vcpu-set / vcpu-pin.
dmesg says:
(XEN) Initializing CPU#0
(XEN) CPU: Trace cache: 12K uops, L1 D cache: 16K
(XEN) CPU: L2 cache: 2048K
(XEN) CPU: Physical Processor ID: 0
(XEN) CPU: Processor Core ID: 0
(XEN) Intel machine check reporting enabled on CPU#0.
(XEN) CPU0: Intel P4/Xeon Extended MCE MSRs (24) available
(XEN) CPU0: Thermal monitoring enabled
(XEN) CPU0: Intel Genuine Intel(R) CPU 2.80GHz stepping 02
(XEN) Brought up 1 CPUs
(XEN) Dom0 has maximum 1 VCPUs
I think this must be some kind of "boot problem": I told Domain0 to use
1 CPU only. I can't tell it to change it because I need Dom0 for this
and it is seeing only one cpu...
any more ideas?
thx,
Andrej
