[one-users] mixed type clusters and MAC persistance

[Matthew Patton]

Just asking a sanity-check question.

If I have both KVM and VMware hosts and not ALL datastores are provided by  
NFS and thus common to all participants then they can't be part of the  
same cluster because when it's time to deploy a VM the source may not be  
available on the intended host? I read that VM templates are generally  
intended to be hypervisor agnostic.

So, is there any way to "steer" a Template or a VM at instantiation time  
to a particular flavor of hypervisor?
Hmm, apparently there is;   
"http://opennebula.org/documentation:rel3.6:template" down near the end of  
the page in the discussion of requirement booleans (REQUIREMENTS =  
"HYPERVISOR=\"vmware\"")

Does anyone use this capability?

When I use 'virsh create' to create a VM, it auto-generates a MAC should  
it not be defined in the specification. Does ONE then do a 'virsh export'  
to find out what MAC address was assigned and then incorporate it into the  
database so that next it will specify it when starting? I know that on  
RHEL derived distros, changing the MAC causes the guest to renumber  
interfaces.
