I would like to reduce the number of vcpu's to a single vcpu on a couple of VM's.
vsphere: ESX 4.1
VM: Hardware version 7
Guest OS: Suse Linux Enterprise Server SLES 10 SP3 (64bits)
Current vcpu(s): 2
Reason: To reduce licensing costs of the DBMS installed.
This possible without any problems/issues?
You can do this. Make sure you power off the VM and if this is a critical machine, I will back it up, even though I have never had any issues in the past.. just to be safe..
SO yes its possible for you to do that... who knows, if u had an overcommited host, now u may get better scheduling time...

Performed the change from multi cpu to single cpu without any problems.
As expected no issues on Linux.
However, I just tried this on Windows Server 2008 R2 64bit Standard Edition also. And it just worked!!!
It was using an ACPI x64 HAL.
I just shutdown changed cpu number in VM settings and it booted.
