Hi guys,

I've started an oVirt 4.1 HE deployment on a Broadwell based server. Then I added to HE a second, older host based on Nehalem. I've downgraded the cluster CPU type to Nehalem to accommodate host2 and it finally reached score 3400. However, when I try to migrate HE vm it fails with the following error:

2017-03-03 20:19:51,814 ERROR (migsrc/b0d38435) [virt.vm] (vmId='b0d38435-5774-4ca9-ad24-70b57b5bc25d') unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: pclmuldq, fma, pcid, x2apic, movbe, tsc-deadline, aes, xsave, avx, fsgsbase, bmi1, hle, avx2, smep, bmi2, erms, invpcid, rtm, rdseed, adx, smap, 3dnowprefetch; try using 'Broadwell-noTSX' CPU model (migration:265)

I believe the problem is in the HE vm XML where the cpu is still configured as Broadwell. how can I change this specific setting without losing the deployment? Please find all the relevant logs at the following link: https://www.dropbox.com/sh/njl9aofhdw10ses/AADf2Ql4GKVIKcbgLivbmjC2a

Besides that, I believe this is a wrong behavior because HE should follow cluster properties (otherwise do not reach score 3400); do you believe is it worth opening a issue on bugzilla?

Thank you,
Stefano.
