Problem getting CPUID mask to work

Hi,

I've got a problem with getting a CPUID mask to work..

The error I get when I vmotion is

Host CPU is incompatible with the virtual machine's requirements at CPUID level 0x80000001 register 'ecx'.

host bits : 0000:0000:0000:0000:0000:0001:1110:1001

required : 0000:0000:0000:0000:00xx:0xx0:0000x:xxxx

refer to KB 1993 etc etc

So Ive modified my vpxd.cfg as follows..

<config>

<!-- <ws1x> -->

<!-- Enables 1.x Web Services compatibility -->

<!-- <enabled>true</enabled> -->

<!-- Enables 1.x Built in Perf data Refresh -->

<!-- <perfRefreshEnabled>false</perfRefreshEnabled> -->

<!-- Location of ws1x persistent data. Default is same directory as vpxd.cfg -->

<!-- <dataFile> C:\ws1x.xml </dataFile> -->

<!-- Location of the ws1x event mapping file. Default is the same directory as vpxd.cfg -->

<!-- <eventMap> C:\ws1xEventMap.xml </eventMap> -->

<!-- </ws1x> -->
