Our VM is running rhel 6.5 and is configuring with 16 cores (2 virtual sock= et with 8 virtual cores) and 240Gb. This virtual machine is running perfectly on the first host R620 : two cpu = E5-2695 v2 - 12 cores on each cpu - and 384Gb of memory. We wan't to move this virtual machine on a new server, Transtec with two E= 5-2650 v3 - 10 cores on each cpu - and 256Gb of memory. We have encountered= high cpu usage on this host. Both servers are running centOS 7.2 and ovirt 3.6. We have already identifi= ed that on the node, many < migrate/N > are causing high cpu usage. We have tried few options : - Pass-Through Host CPU - Configure NUMA : numa node count =3D 2, numa pinning The first day the machine was running, everything is ok and migrate threads= disapeared, but on the second day, high cpu and migration thread were back= . Oracle services are being restarted everyday for cold backup but not the = virtual machines. I don't know if looking in the Numa options is a good idea and I don't why = the everything is running ok on the R620 (perhaps the available memory) Thank you for your advices.
