After rebuilding our VM Server (running 1.04) we are experiencing 100% CPU Load within our MS SBS 2003 VM (2 processors assigned). The host is a Supermicro P4DP8 with 2 Xeon 2.4GB processors with HT turned off 4GB RAM (2GB allocated to the VM). The CPU load in the web management interface is reporting 160% +.
We noticed a discrepancy in how the vmware.log file reports the CPUs after rebuilding. Old logs, prior to rebuild read:

The VM performed fine under this config. However, after rebuild this section of the log reads:

The host info section caught our eye-instead of seeing 2 processors with 1 thread per core VM Server is now reporting one CPU with 2 threads. This is not correct, and we feel it may be related to our problem. What's baffling is it is the same hardware config. and an identical (so we think) build before and after!
If we temporarily turn on HT in the BIOS this section of the log reports "This machine has 2 physical CPUS, 2 total cores, and 4 logical CPUs."
We've also tried HT on while specifying the CPUs to use and not use in the VMX. Still the VM's performance was awful.
We rolled back to 1.03 and even tried 2 beta with the same result and same reporting of the CPU config.
The host is 32-bit Win XP SP2.
Any recommendations would be greatly appreciated as we are stumped.,
Thanks in advance for you time,
