Not done for 5.5, deferring to 5.6 Hmm, the number that virt-manager lists as the 'Maxmimum virtual CPUs' is the max supported hypervisor value we get from libvirt. It's not based on how many logical/physical cpus are present on the host. AFAIK, the max cpus KVM supports in RHEL5 is 16, and qemu refuses to run if more are specified. The overallocation message is kind of bogus, I agree: it doesn't exist anymore upstream. We can probably just change the message to say 'may cause out-of-memory errors', but I don't think it's really even worth it (figuring that it would invalidate all translations, etc.) As far as the graph issue, I can't reproduce any weirdness: things seem to top out fine at 100%. So I'm closing this WORKSFORME. If you can still reproduce with latest RHEL, can you answer the following: Is the weirdness on an individual VM CPU graph, or the host row CPU graph? Can you take a screenshot of the weirdness? If you run virt-manager --no-fork from the command line, are any errors printed to the console? |
