Hi,Martin

Thanks a lot.
My virtual platform sticks to Xen kernel.
Because our development relates with kernel version, our virtual guest OS need smp kernel.
Please see my vm configure file:
disk = [ 'file:/var/lib/xen/images/vm1/hda,hda,w', 'phy:hde,hdb,r' ]
memory = 256
vcpus = 1
builder = 'linux'
kernel = '/tmp/YaST2-15684-Ng5sdV/vmlinuz-2.6.16.13-4-xen'
ramdisk = '/tmp/YaST2-15684-Ng5sdV/inst-initrd'
name = 'vm1'
ip = '192.168.125.99'
netmask = '255.255.255.0'
gateway = '255.255.255.128'
interface = 'eth0'
vif = [ 'mac=00:16:3e:4e:e5:46' ]
localtime = 0
on_poweroff = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
extra = 'install=hd:/dev/hdb TERM=xterm textmode=1 hostip=192.168.125.99 netmask=255.255.255.0 gateway=255.255.255.128 netdevice=eth0'


Question: how to modify "kernel" parameter to satisfy my demand that guest OS is smp? I have tried that modify kernel = '/tmp/YaST2-15684-Ng5sdV/vmlinuz-2.6.16.13-4-smp',
But I doesn't work.

If you're guest is paravirtualized, then you'll need to stick to a Xen
kernel.  A regular kernel (I assuming the one you're suggesting is a
regular SMP kernel) will only work with a HVM guest, which obviously
depends on suitable hardware.

Out of interest, why do you want to change the Kernel you're using?  I
wouldn't imagine there's much difference between the one's your
suggesting apart from the Xen patches.
