Ovm_utils: can create cpu compatibility group, but can't add vm servers

Question

Hi,
I am running a VM server pool with mixed CPU types. Today I took a closer look at Wim Coekaerts ovm_utils, which revealed that ovm_utils is able to create (arbitrary) cpugroups and move VM servers into them. I thought that this would be a nice thing to try, since it had always bogged me, that OVMM was too strict when it comes to live migration of VMs between VM servers with non-identical CPUs and that I had always use xm migrate -l to perform that task manually.
Now, setting up a new cpugroup using ovm_managercontrol was easy and went like this:
ovm_managercontrol -u admin -p ********** -h localhost -c createcpugroup -n ASM_POOL
Which turn created a new cpugroup, as I verified with listcpugroups:
[root@oraclevmm ovm_utils]# ovm_managercontrol -u admin -p *********** -h localhost -c listcpugroups
Oracle VM Manager Control utility 0.5.2.
Manager version : 3.1.1.365
Connected.
Command : listcpugroups
Group : Default_Intel_F6_M26
Server : oraclevms04
Server : oraclevms06
Server : oraclevms05
Group : ASM_POOL
Group : Default_Intel_F6_M44
Server : oraclevms01
Server : oraclevms02
Server : oraclevms03
Group : Default_Intel_F6_M15
Server : oraclevms08
Exit...
However… putting any server into that group doesn't work:
ovm_managercontrol -u admin -p *********** -h localhost -c addservertocpugroup -s oravlevms08 -n ASM_POOL
Oracle VM Manager Control utility 0.5.2.
Manager version : 3.1.1.365
Connected.
Command : addservertocpugroup
Adding Server to CPU Compatibility group.
Exit...
Now… no error message, but no dice either. The vm server oraclevms08 still belongs to its initial cpu group. It didn't work with any other VM server I tried.
Has anybody else tried this yet?

Hi,
I used exactly the same commands as you but with :
Oracle VM Manager Control utility 0.5.2.
Manager version : 3.1.1.305
This worked fine, from what i can see you just mis-typed your servername:
-s oravlevms08 --> oraclevms08
