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:<br>
<br>
2017-03-03 20:19:51,814 ERROR (migsrc/b0d38435) [virt.vm] (vmId='b0d38435-5774-4ca9-ad24<wbr>-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)<br>
<br>
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: <a href="https://www.dropbox.com/sh/njl9aofhdw10ses/AADf2Ql4GKVIKcbgLivbmjC2a" rel="noreferrer" target="_blank">https://www.dropbox.com/sh/njl<wbr>9aofhdw10ses/AADf2Ql4GKVIKcbgL<wbr>ivbmjC2a</a><br>
<br>
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?<br></blockquote><div><br></div><div>I would consider opening a BZ to track this. Adding some people who may have some insight on the issue.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
