Hi guys,
We are doin some experiments with kvm virtualization with new servers. We want to migrate from all of our nodes, from hyper-v to kvm.
Well i know some of you do not like hyper-v for virtualizing linux. But trust me its performance quite good.
Can you give me any real life info about kvm performance with high end dedis ?
New nodes specs: Intel(R) Xeon(R) CPU E5-2660 v2 @ 2.20GHz X 2 10 core for each socket. with ht total 40core. 256gb rami 600gb 15k-sas x 12 with raid 6.
With these specs how many vps will be reasonable ? (not oversell ! ) ram and cpu wont be bootleneck, my concern is io wise. Im chcecking some documents and it seems kvm and qcow2 performance with virtio enabled not as good as hyper-v with vhd or vhdx.
Im using solus atm. Experimenting disc cache options.
Will be really apreciated for any info.
Thanks ;)
