Re: [Xen-users] XEN CPU ballooning?

[George Shuklin <george.shuklin@xxxxxxxxx>]

Good day. 

As this exists in XCP, you can set up cpu-max to value not higher than
available on host. And you can change amount of actually used CPU in
realtime without reboot.

And you can even create 10 VM with 4 vCPU on each running on host with 4
cores available. (they will have concurrent access according to vCPU
scheduler).
