Running EVE-NG in KVM
Posted: Wed Oct 17, 2018 7:33 pm
Hi guys,
I've installed a Centos7 with KVM, and inside that host machine, i've created a EVE-NG VM, and started to run nodes inside. Compared with with my old setup (bare metal install), running nodes (IOSv only) seems sluggish, and even spinning one router takes 5min+, and when finally does start, Guest VM processor reports high usage (~30%), when compared with the bare metal install. I've tried to troubleshot KVM virtualization issues, but no success so far.
Any sugestions are apreciated!
My setup is as follows.
Host (centos7 with KVM):
2x Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz
128GB RAM
Lots of storage
Guest VM (EVE-NG):
10x CPU cores from the host
64GB RAM
I've checked if KVM/VT-x support is enabled, and seems the settings are right.
Checks on VM (EVE-NG):
- kvm-ok
- lscpu
Checks on Host server:
