If the CPUs are "floating" as opposed to "pinned", it's possible for a busy VM to use all the available processors if the other VMs are idle, right? E.G., if I have 4 CPUs and 3 VMs and none of my CPUs are pinned, and one of my VMs is compiling a kernel while the other two are idle, the busy kernel-compiling VM will use all 4 CPUs, right? It won't be limted to only 2 or something, right? I'm curious because I've noticed a few people and documents mention pinning one cpu to each VM. I assume is is because they don't want a situation where a low-priority but high-processor-usage task on one VM causes another VM with a sporadic but high-priority job to hang out waiting for the low-prioroty job to finish. Ok, now that I've read my own question, I guess my real question is, can someone point me to a good document that descibes how Xen allocates available processors..? If there isn't such a document, please take a shot at the question above... Thanks! -Dylan _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
