Title:
high IRQ-TL
Looking through old bug tickets... can you still reproduce this issue
with the latest version of QEMU? Or could we close this ticket nowadays?

Disabling huge pages seem to help.
Strangely this should theoretically increase the issue but it so far we have
not seen issues after disabling THP.
(have not seen high load spikes in a week but this might also be holiday
related)
So other people can try it out:
echo never >/sys/kernel/mm/transp
Seeing the same here, also happens on overbooked hypervisors.
Just one or two hosts have this behaviour.
We are using:
qemu-kvm 2.0.0+dfsg-2ubuntu1.25
libvirt-bin 1.2.9
kernel 3.13.0-92-generic
We are using contrail as a SDN.
It looks like i
overcommit ratio on latest server i had the problem is 3.6 (3.6 vcpu for
each cpu), would that be part of the problem? i see other servers that
never had the problem with over commit ratios as high as 4.1

maybe first part is not clear, here it goes again
this happens on some hypervisors at random times, not all hypervisors
at the same time, and affects all vm on the hypervisor
