Hi Team.
When i create a vm, my vms are lagging so much when I run any application in ubuntu
this proably is cause by one of three proablems 1 you are useing qemu not kvm 2 you created a flaoting vm (without cpu pinning) and you are using the isolcpus kernel command line option on the host 3 you have and disk io performance (locally or over the network if you are using network storage)
we really dont have anything to go on as we dont know what os you are using beyond ubunut or how you deployed openstack and which version.
but those are they 3 things that normaly result in poor vm performance. using qemu, cpu contention or low disk io.
