vCPU change in VM is not dedected in RHEL 4.8
Dear All,
I have changed the number of vCPU from 1 to 4 in a Vsphere console for a virtual machine running RHEL 4.8 but the change is not dedected in OS. The server is still running with 1 CPU. Below are the steps I did to change the number of vCPUs. 1. Powered off the VM -> Edit Settings -> Changed the vCPU number to 4 -> Apply. 2. Powered on the VM Once the OS came up I checked /proc/cpuinfo still it showed CPU - 1. I am not sure if i am missing some thing... Appreciate any help to resole this issue. $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU E5540 @ 2.53GHz stepping : 5 cpu MHz : 2525.591 cache size : 8192 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss nx rdtscp lm constant_tsc pni popcnt bogomips : 5056.39 $ uname -m i686 $ getconf WORD_BIT 32 $ cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 8) |
With a system that old they probably had a separate SMP kernel. Maybe see what this produces
Code:
grep -iE "(nr_cpus|smp)" /boot/config-$(uname -r) |
Thanks a lot for your response syg00.
Please find the details below $ grep -iE "(nr_cpus|smp)" /boot/config-$(uname -r) CONFIG_BROKEN_ON_SMP=y # CONFIG_X86_BIGSMP is not set # CONFIG_SMP is not set CONFIG_X86_FIND_SMP_CONFIG=y |
I'd reckon you need a SMP kernel - I think that would be ...ELsmp. What does "uname -a" output ?.

I ve installed SMP kernel and it worked like a charm.. Thanks a lot for your advice syg00...
