I am very grateful for your response. I have used the following deployment scenario. 2 host with XCP-ng 8.2 1st host has 2CPU socket each of 24 core (96vCPU) 2nd host has 2CPU socket each of 6 core (24 vCPU)
The value "xen.vm.vcpu.max" is currently set to 16. And the dynamic scale for template is turned off. I will further test as per the details provided. I will revert you back after the test. Thank You very much.
