Hello,

I've got following problem with XCP 1.5 Beta:
I had working pool with 2 hosts running XCP 1.1 and could use live VM migration back and forth between hosts. Bit after upgrading to XCP 1.5 Beta live migration is not working anymore, complaining to CPU incompability.
Here is CPU info for both hosts:
Host #1:
cpu_count                : 4
                   vendor: GenuineIntel
                    speed: 1995.033
                modelname: Intel(R) Xeon(R) CPU           E5335  @ 2.00GHz
                   family: 6
                    model: 15
                 stepping: 11
flags: fpu de tsc msr pae mce cx8 apic sep mtrr mca cmov pat clflush acpi mmx fxsr sse sse2 ss ht nx constant_tsc aperfmperf pni vmx ssse3 hypervisor tpr_shadow vnmi flexpriority
                 features: 0004e33d-bfebfbff-00000001-20100800
    features_after_reboot: 0004e33d-bfebfbff-00000001-20100800
        physical_features: 0004e33d-bfebfbff-00000001-20100800
                 maskable: no

Host #2:
cpu_count                : 2
                   vendor: GenuineIntel
                    speed: 2400.158
                modelname: Intel(R) Xeon(R) CPU            3060  @ 2.40GHz
                   family: 6
                    model: 15
                 stepping: 6
flags: fpu de tsc msr pae mce cx8 apic sep mtrr mca cmov pat clflush acpi mmx fxsr sse sse2 ss ht nx constant_tsc aperfmperf pni vmx est ssse3 hypervisor tpr_shadow
                 features: 0000e3bd-bfebfbff-00000001-20100800
    features_after_reboot: 0000e3bd-bfebfbff-00000001-20100800
        physical_features: 0000e3bd-bfebfbff-00000001-20100800
                 maskable: no

I've tried to set pool-other-config:cpuid_feature_mask to fffbff7f-ffffffff-ffffffff-ffffffff
But it didn't help.

Is there a way to overcome this problem? Or it is not possible with new version?

Thanks in advance,
Eugene
