Manao ahoana, Hello, Bonjour,
I would like to launch several KVM guests on a multicore CPU.
The number of the KVM process is over the number of physical cores.
I would like to limit each KVM process to say... 10% of CPU
I first use "cpulimit "
Would you know some better way to limit them? it's in order to avoid 4
VM to hog all the 4 hardware cores.
KVM processes are just like Linux processes, so you can pin them and
renice them.
There is support for pinning virtual CPUs to physical CPUs in libvirt,
eg:
virsh vcpupin GuestName 0 0
but you can also use Linux tools. "tuna" is one such program which I
think is in Fedora, or upstream here:
http://git.kernel.org/?p=linux/kernel/git/acme/tuna.git;a=summary
Another tool is "renice".
Rich.
