How can I control all process using some cpu core.
Dear All,
I use ubuntu 14.04 running KVM and had 20 vm-guest. I found out, some time these vm-guest packets average latency will over 3000 ms and packets loss occur. Normal average latency is about 400~800 ms.
these vm-guest cpu still on the 98%, because I use tester send more traffics.
How can I control all process (not vm) to cpu node 0/1_vCPU 0 and 1 ? I want to resver 4 vCPU core to them.
The other vcpu is for vm-guest( one vm-guest assign one vcpu).
This is lab situation.
Thanks,
Jalee
