I was looking for a solution to the problem in Google, but I did not find it.
I installed Ubuntu 14.04.5 LTS with Xentools on Citrix XenServer 6.5 with SP1, the specification of the host is as follows: Intel Xeon X3430, 12GB RAM, local storage of HDD 512Gb. After the configuration of the VM, everything works fine, CPU utilization is not more than 10%. configuration VM: 4 vCPUs, topology: 1 socket with 4 cores per socket, 6000 Mb RAM, local storage on HDD (60Gb)
After exporting the VM(.xva file) to another host (with the following configuration: Intel Core 2 Quad Q6600, 12GB RAM, local storage of HDD 512Gb) the VM began to lag terribly and brake, while XenServer on the new host did not show a large CPU load, although the CPU load in the VM was jumping to 100%
For the test, I export the same VM to another host with CPU: Intel Xeon E5405 and the situation was repeated, the CPU VM load jumped to 100%, VM lagged and braked.
I have almost all servers with different processors, how can I transfer virtual machines from host to host so that they work correctly and predictably? Maybe there is a special kind of export or additional settings?
If this problem can not be solved, then between which processors can you transfer virtual machines? maybe there is a compatibility table?

Hello!!
I was looking for a solution to the problem in Google, but I did not find it.
I installed Ubuntu 14.04.5 LTS with Xentools on Citrix XenServer 6.5 with SP1, the specification of the host is as follows: Intel Xeon X3430, 12GB RAM, local storage of HDD 512Gb. After the configuration of the VM, everything works fine, CPU utilization is not more than 10%. configuration VM: 4 vCPUs, topology: 1 socket with 4 cores per socket, 6000 Mb RAM, local storage on HDD (60Gb)
After exporting the VM(.xva file) to another host (with the following configuration: Intel Core 2 Quad Q6600, 12GB RAM, local storage of HDD 512Gb) the VM began to lag terribly and brake, while XenServer on the new host did not show a large CPU load, although the CPU load in the VM was jumping to 100%
For the test, I export the same VM to another host with CPU: Intel Xeon E5405 and the situation was repeated, the CPU VM load jumped to 100%, VM lagged and braked.
Do I understand correctly that this situation is connected with the incompatibility of processors? Is this indicated on the page? https://docs.citrix.com/fr-fr/xencenter/6-5/xs-xc-vms-exportimport/xs-xc-vms-export.html
