I need a container that supports real time threads. According to the
documentation, I can do something like this: <domain type='lxc'> <name>test1</name> <uuid>e7446f55-3d59-4af0-90b2-d1498ac4370d</uuid> ... <vcpu placement='auto'>2</vcpu> <cputune> <vcpusched vcpus='0-1' scheduler='fifo' priority='1'/> </cputune> ... </domain> The document describes the vcpusched element as follows: The optional vcpusched elements specifies the
scheduler type (values batch, idle, fifo,
rr) for particular vCPU/IOThread threads (based on vcpus
and iothreads, leaving out vcpus/iothreads
sets the default). Valid vcpus values start at 0
through one less than the number of vCPU's defined for the domain.
Valid iothreads values are described in the iothreadids
description. If no iothreadids
are defined, then libvirt numbers IOThreads from 1 to the number of
iothreads available for the domain. For real-time
schedulers (fifo, rr), priority must be
specified as well (and is ignored for non-real-time ones). The value
range for the priority depends on the host kernel (usually 1-99).So I *think* my xml is correct for this, but it doesn't seem to work--I still can't create real time threads in my container. Am I missing another configuration step somewhere? Peter |
