Hi all,
How can I avoid sharing interrupts in a kvm guest? I have installed a debian 7 guest in a centos 6.4 host with 5 virtio vnics and 2 virtio disks and irq11 is used by eth2, eth3, eth4 and irq10 eth0, eth1 ...
Is it possible to avoid this situation??
Thanks.

Make sure that the irqbalance service is installed, up and running
AFAIK irqbalance can only dynamically set CPU affinity for irq handlers, but is unable to reassign irq numbers.
Is ACPI/APIC enabled in your qemu options? Usually virtio devices in /proc/interrupts can be seen as two handlers per device - config request queue and data transmission requests queue. 10.10.2013 11:14 пользователь "Manuel Wolfshant" wolfy@nobugconsulting.ro написал:

Yes I have enabled ACPI/APIC ... I have tried with another FreeBSD guest, and same problem ... Is it possible to assign different interrupts for pci also??
