When it comes to software and configuration (apart from the obvious stuff), all my Xen hosts are identical - OpenSuSE 11.4 x86_64. I was running older OpenSuSE Dom0's before (11.2) and never got live migration to work properly - but I think there were different errors and issues.
No, I was rather asking for hardware differences (in particular memory sizes) on the various hosts, and whether migration perhaps works one way but not the other.

Yes, there are hardware differences. One of the servers is a HP workstation with 16GB of RAM and one 4-core I5-750 CPU. This one is used mainly for installing new DomU's (after the DomU reaches 'production' status, it's moved to one of the other hosts) and testing. One of the servers is an IBM x3400 with 32GB of RAM and two 2-core Xeon 5120 CPU's. This one is running mainly internal stuff. Two of the servers are Intel S5000PSL servers with 32GB of RAM and two 4-core Xeon E5405 CPU's. I'm using this Xen hypervisor options: dom0_max_vcpus=2 dom0_vcpus_pin dom0_mem=2048M'. It doesn't matter which host I'm migrating from or to - the symptoms are always the same. Danilo -- Danilo Godec, sistemska podpora / system administration Predlog!
