Hi, We've got a problem with a critical machine which running Oracle Database and if someone can help us it would be very nice.
Our VM is running rhel 6.5 and is configuring with 16 cores (2 virtual socket 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 E5-2650 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 identified 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 = 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. Styve
