Yes we are close with turning Xen1 down to maximum on Xen2 we have successfully freed up all VM's from our old environment are in the process of resetting those servers and bringing them into the cluster but with snafu of 10g ports on the cat6 patch panel I need to wait a week which means updates are going to be pushed two weeks out.
I will report back ones I have resources at a better state. But it is still odd that now that Xen1 and Xen2 are out of maintenance and balanced our properly some of the VM's cannot migrate from xen1 to xen2 those are the same large VM's that were halting this move.

Unable to migrate VM Some more considerations: How much free CPU, memory resources are available on your remaining hypervisors ? If your XenServer pool resource usages are near to their maximum limits, putting one hypervisor into maintenance could very well push the usage over the limits for remaining hypervisors/pool. Check global settings cluster.cpu.allocated.capacity.disablethreshold and cluster.memory.allocated.capacity.disablethreshold. I think their default value is 0.75 or 75% of total. You can increase these limits, or shutdown some non-critical instances running on your remaining hypervisors to see if you can migrate more instances off the hypervisor you are patching. As a last resort, you could just shutdown the remaining instances and reboot the hypervisor and restart stopped instances once the hypervisor is back !
