I would rather suggest you to deal with flavor/images metdata and host aggregate for such segregation of cpu capacity and versionning.<br><br>If someone have another technics I’m pretty curious of it too.<br><div class="gmail_quote"><div dir="ltr">Le ven. 26 janv. 2018 à 17:00, Gary Molenkamp <<a href="mailto:molenkam@uwo.ca">molenkam@uwo.ca</a>> a écrit :<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I'm trying to import a Solaris10 image into Ocata that is working under<br>
libvirt/KVM on a Fedora workstation. However, in order for the kvm<br>
instance to work, it needs a few additional parameters to qemu that I<br>
use in the libvirt XML file:<br>
<br>
<cpu match='exact'><br>
<model fallback='allow'>Westmere</model><br>
</cpu><br>
<br>
<qemu:commandline><br>
<qemu:arg value='-no-kvm-irqchip'/><br>
</qemu:commandline><br>
<br>
For the first parameter, I know I could modify the /etc/nova/nova.conf<br>
of the entire hypervisor on the compute node to Westmere and limit<br>
instances to that hypervisor, but that limits additional instances on<br>
that compute node. Is there a way to instruct nova to use a westmere<br>
cpu for a single instance?<br>
<br>
Likewise, how can I pass the -no-kvm-irqchip option for instances of<br>
this image?<br>
<br>
Any pointers would be appreciated.<br>
<br>
Thanks<br>
