Question regaring correct usage of CPU shares
Hi there,
I have a question regarding the shares option of the cputune section. I
want to illustrate my question with the following example. Let's assume
I have two virtual machines like the following on four dedicated core
with two threads each:
VM1:
<cputune>
<shares>512</shares>
<vcpupin vcpu="0" cpuset="0"/>...

Cputune causing VM to show usage as hardware interrupts
Hey All,
What is the correct method for using cputune to use a percentage of a host
core? From testing I currently have period set to 10,000 and quota set to
3,500. This gets me 35% of a used core on the host (36 3.4 2:42.20
qemu-system-x86) however when running stress inside the VM I am showing
this usage in top;w

cputune shares with multiple cpu and pinning
Hi,
I have found the cpu time partitioning based on cpu shares weights not
very intuitive.
On RHEL64, I deployed two qemu/kvm VMs
VM1 with 1 vcpu and 512 cpu shares
VM2 with 2 vcpus and 1024 cpu shares
I pinned their vcpus to specific host pcpus:
VM1 vcpu 0 to host pcpu1
VM2 vcpu 0 to host pcpu1, VM2 vcpu 1 to host pcpu2
I executed inside the VMs a simple process that consume all

Yes, thanks! Does in near feature libvirt devs integrate this ability
to domain format? As i understand all qemu stable features supported
by libvirt. And data plane for virtio-blk is
