Hi,
I have one Ovirt cluster and under this cluster all the guest machines (such
as centos,ubuntu,debian etc) almost 160 RCU processes running....
i searched on google about the RCU (It's kernel process "read-copy-upate")

I want to know how i can modify this 160 processes to 10-20 or how i can to
disable it....is there any bed impact if i disable it....
Thanks,

Hi Punit,
we need to do a bit of a research on this one.
In order to make sure we keep track of it, do you mind opening an RFE (BZ)
with all the relevant details, including the hardware that you're using,
guests config, how busy the guests/host are, Which hypervisor is used and
the versions.
Thanks,
Doron
