Thanks Jonathan! I was actually following the info in the man page / online wiki article heheh ;o). [so...little note for whoever may be reading this that maintains those sources of information, we need to update them! heheh].
By the way, your suggestion did not seem to fully work though, here's what happened: [root@xcat ~]# ls /vms/shared/ vm10 vm9 [root@xcat ~]# clonevm -t vm9 vmmaster01 vm9: Successfully copied to vmmaster01 [root@xcat ~]# ls /vms/shared/ vm10 vm9 vmmaster01 [root@xcat ~]# tabdump vm #node,host,migrationdest,storage,storagemodel,cfgstore,memory,cpus,nics,nicmodel,bootorder,clockoffset,virtflags,master,vncport,textconsole,powerstate,beacon,datacenter,guestostype,othersettings,vidmodel,vidproto,comments,disable "vm9","blade03",,"nfs://xcat.core.cloud/vms/shared",,"nfs://xcat.core.cloud/vms/shared","2048","2","eth0",,,,,,,,,,"vlan5",,,,,"VM auto created by Moab", "vm10","blade03",,"nfs://xcat.core.cloud/vms/shared",,"nfs://xcat.core.cloud/vms/shared","2048","2","eth0",,,,,,,,,,"vlan5",,,,,"VM auto created by Moab", [root@xcat ~]# tabdump vmmaster #name,os,arch,profile,storage,storagemodel,nics,vintage,originator,comments,disable "vmmaster01","centos5.5","x86_64","compute","nfs://xcat.core.cloud/vms/shared",,"eth0","Sun Jul 24 11:28:15 2011","root",, [root@xcat ~]# nodeadd clonevm01 groups=centos5.5-stateless,esxvmmgt,failgroup,moab,vlan5,all [root@xcat ~]# clonevm clonevm01 -b vmmaster01 clonevm01: Error: Unable to identify plugin for this command, check relevant tables: nodehm.mgt;nodehm.power,mgt [root@xcat ~]# So i ended up adding the necessary nodehm entries: [root@xcat ~]# tabdump nodehm #node,power,mgt,cons,termserver,termport,conserver,serialport,serialspeed,serialflow,getmac,comments,disable "ibm","ipmi","ipmi",,,,,,,,,, "blades","hpilo","hpilo",,,,,,,,,, "vm9","esx","esx",,,,,,,,,, "vm10","esx","esx",,,,,,,,,, "clonevm01","esx","esx",,,,,,,,,, [root@xcat ~]# But that still would not work: [root@xcat ~]# clonevm clonevm01 -b vmmaster01 no host or cluster defined for guest clonevm01 [root@xcat ~]# So i added the vm to the "vm" table and...

I'm not very happy with how it works though... :o) I understand it is necessary to specify the hypervisor where the VM should be placed BUT "clonevm" should be smart enough to do that! I basically manually "reconfigured everything", the experience is almost the same as adding a new vm (and that's not what i expected)... I also noticed the "clonevm master creation" step did not update the vm.master field for the vm i cloned from... Which isn't consistent with how things work for KVM (well, at least not according to what you showed me)... Either way, it seems to be working, i guess :o). Thanks!
