Re: [Xen-API] Heterogeneous pools question

He should not need to force=true the migration, since he is using CPU
feature leveling.  With earlier versions of XCP, force=true is not required
once CPU features are leveled.  Is that no longer the case with XCP 1.5?

Hi Eugene,

If you call vm-migrate with the option "force=true" then the CPU
compatibility check should be disabled.

Subject: [Xen-API] Heterogeneous pools question

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

                  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
