Because from what I gather, VirtualDomain RA works only with virsh (KVM/Xen), but I need OpenVZ. The second reason is that I have groups of virtual machines that work on the same filesystem. There is no way to get this working with VirtualDomain RA, especially given the next point: > Yes, migration only works without order-contraints the migrating service > depends on ... and no way to force it. > Use existing, working and tested RAs. Well, then I will need to hack unfortunately :( I hope it is possible for a resource agent to instruct other agents to move...
