Hi ! What is optimal setting for oVirt KVM guests for database hosting on Xeon server (2 x Xeon 4-core each) (in my case this is Firebird based accounting/stock control system with several clients active)? 1st of course its preallocated disk image. VirtO-SCSI enabled Migration disabled. Balloning disabled. CPU shares disabled Pass-through host CPU enabled What should be other CPU settings? For example, Xeon have 2 threads per core, should I set in oVirt 1 or 2 threads per virtual CPU? IO Threads on or off? Any idea of NUMA settings ? Node running 4 VMs total, CPU load is quite low, RAM is enough to preallocate for each VM + 4GB for node itself. Thanks in advance ! Andrei
