Re: NUMA issues on virtualized hosts
...e the performance drop. You can try enabling iothreads: https://libvirt.org/formatdomain.html#elementsIOThreadsAllocation This is a qemu feature that allows you to create more I/O threads and also pin them. This is an example how to use them: https://libvirt.org/git/?p=libvirt.git;a=blob;f=tests/qemuxml2argvdata/iothreads-disk.xml;h=0aa32c392300c0a86ad26185292ebc7a0d85d588;hb=HEAD And this is an example how to pin them: https://libvirt.org/git/?p=libvirt.git;a=blob;f=tests/qemuxml2argvdata/cputune-iothreads.xml;h=311a1d3604177d9699edf7132a75f387aa57ad6f;hb=HEAD Also, since iothreads are capable of handl...

libvirt doesn't boot kVM, hangs, qemu on 100% CPU
