Hi
I install CentOS 5.4 and try to use Xen....
But when I deploy some VM with Virt-manager and specify 2 or more VCPUS to use, when start the vm it start with just one CPU... On this VM I install Windows 2003 Server... This the file of VM:
name = "Avision" uuid = "625139bf-1ad3-86fc-45e6-e8efbb9db643" maxmem = 2048 memory = 2048 vcpus = 4 cpus = "0,1,2,3" builder = "hvm" kernel = "/usr/lib/xen/boot/hvmloader" boot = "c" pae = 1 acpi = 1 apic = 1 localtime = 1 on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" device_model = "/usr/lib64/xen/bin/qemu-dm" usb = 1 usbdevice = "tablet" sdl = 0 vnc = 1 vncunused = 1 keymap = "pt-br" disk = [ "phy:/dev/etherd/e3.3,hda,w" ] vif = [ "mac=00:16:36:2f:fd:7c,bridge=xenbr0,script=vif-bridge,model=ne2k_pci" ] parallel = "none" serial = "pty"
But, on windows I just see one CPU... I don't understand why this happen!!
Thanks for any help

Did you verify that Xen has those 4 CPUs assigned to the guest? Did you install Windows with SMP support or add SMP support after you added more CPUs?
Hi... I already has the same VM running on Xen 3.4.1 and the 4 VCPUS appears on WIndows system...
Now I downgrade to xen 3.0.3 but ewven I define VCPUS =4 and the number o CPUS on five VM, the cores not be present....
When I start Virt-manager, the VM shows me 4 CPUS, but when I start the VM, quiclky change to 1 VCPU...
On xend.log I get this:
... [2010-04-04 01:49:46 xend 4191] DEBUG (image:330) args: vcpus, val: 4 ...

I don't think so, type xm dmesg and see what the Xen Version says.
I'm completely "stock" CentOS 5.4 virt install and I have:
Xen version 3.1.2-164.15.1.el5 (mockbuild@centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) Wed Mar 17 11:22:38 EDT 2010
Which indicates Version 3.1.2 AFAIK.
Sorry!
The correct version is 3.1.2

Did you upgrade and then downgrade on the same machine it's not working properly on or are they different physical machines?
I upgrade the entire system

If you mean that you upgraded Xen on the same system you recently downgraded to stock Xen on, it makes me wonder what else you modified, particularly because you are having kernel problems when you start VMs. Does the VM work on another physical host with a stock CentOS install? Does the VM work on the same physical host with a fresh stock CentOS install?

Verify that your windows is using the multi-cpu HAL. If it uses the single-cpu HAL then you won't be able to see more than 1 cpu.
See microsoft website and google for more information.
