[libvirt] [PATCH] docs: Try harder to uninstall
by Michal Privoznik 23 Feb '16

23 Feb '16

Imagine you have partially installed libvirt, or maybe you're just running 'make uninstall' from a different version than 'make install' has been ran. One way or another, we are doing plain 'rm' instead of 'rm -f' and thus not trying hard enough when uninstalling. In the rest of our code we stick with -f switch. Do that for docs too.

[libvirt] libvirt-guests.sh not correctly working - patch included
by Draget 23 Feb '16

23 Feb '16

Greetings, this mail is sent via CC to ubunutu-devel, because I am not 100% sure if the found formating issue might originate from some ubuntu issue. libvirst-guests.sh on Ubuntu Xenial would not work correctly for me. Only one of the guests would be correctly suspended while the others were killed violently. Package: libvirt-bin Version: 1.3.1-1ubuntu2 /usr/lib/libvirt/libvirt-guests.sh The script writes a list of the VMs it will manage into /usr/lib/libvirt/libvirt-guests but I noticed it was in the format: <url> <vm uuid> <vm uuid> <vm uuid> and only the first VM was handled. After reading through the script and doing some try & error patches, I figured that the correct format should be: <url> <vm uuid> <vm uuid> <vm uuid> i.e. with no new lines. The attached patch makes sure the returned list of VMs does not contain new lines. This fixed the issue. Additionally I would suggest adding an information message on line line 444. Changing: [ -f "$LISTFILE" ] && return 0 to: [ -f "$LISTFILE" ] && echo "No VMs started by libvirt-guests.sh, not doing anything." && return 0 Regards, Michael Gajda

Hmm, ok. I guess the question is what does "online" mean in the context of a libvirt client. It used to be that "online in host" and "able to run vcpus" were the same thing, but now they're not. > Just to clarify, since the naming is not very explicit: nodeinfo > reports *online* CPUs only, and each <cpu> element in capabilities > is supposed to represent an *online* CPU.

What it's really about is mitigating the case where the system is overcommited in terms of number of virtual cores, but not in terms of number of virtual threads. Without dynamic split core the system will make more use of the host's threading capabilities, with it, it will do a much better job. > overcommitted, but it has some overhead of its own because of the need > to split the core when entering KVM and restoring the previous > configuration when exiting it. Hmm.. I guess there would be a little extra latency on entering and exiting the guest. I don't know if it's at all significant compared to the already substantial cost of entering/leaving the guest. > Splitting cores manually, on the other hand, is less flexible but > gives the admin complete control over resource allocations and has > no overhead, which makes it critical for fine performance tuning. Well.. except manual splitting can only be done system wide an only do, whereas dynamic split-core can do it per-core which might allow it to better match the workload. > So unless my understanding is off, I believe we need to expose the > topology in a way that enables both use cases.

My first reaction is to dislike the idea of adding yet another variable that affects the results of CPU models. But considering that we are moving towards a design where libvirt must not assume or query any low-level detail from CPU models at all, maybe this won't be harmful. -- Eduardo
