Thread-topic: CPU/VCPU sharing

Hi All,

I am new to Xen, and would like to know if anyone can help with a problem I have.

I have a dual - Quad Core Intel 5535 VT 2.66 server, with 24G ram running CentOS5 dom0 and domU (both 64 bit). Everything works great and I am SUPER impressed with the efficiency of Xen (i have always been a UML man). I would however, like to run a single domU domain, with a single VCPU, but get the power of say, 7 cores, leaving 1 to the dom0 instance. First off, I would like to know if this is possible.

In my config file I have specified cpus = "1-7" and vpus=1 in the hope that the 1 vcpu would be an almighty powerful one, but this isn't the case. There is no errors booting it up, and
     [\047cpus\047, \0470-7\047]
appears in the xend logfile.

Here is a copy of the config file.

name = "test1"
builder = "hvm"
memory = "20000"
disk = [ 'file:/virtual/test1,hda,w', ]
vif = [ 'type=ioemu, mac=00:16:3e:18:34:76, bridge=xenbr0', ]
uuid = "d8a2a092-399a-ecb9-24fb-7caf66f883b2"
device_model = "/usr/lib64/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
vnc=0
# vncunused=1
apic=1
acpi=1
pae=1
cpus="0-7"
vcpus=1
usb=0
serial = "pty" # enable serial console
on_reboot   = 'restart'
on_crash    = 'restart'

Any help / advice / comments and greatly appreciated.

Regards, Matt Hanna
