This patch adds a

This is the new ovirt agent that implements the QMF API. This is just its humble beginnings. The goal was to implement the create VM method on VMs but it turns out we need to specify the VM pool in order to do that. This is currently hardcoded to '5' and works locally but would likely not work elsewhere. What does work well is listing/querying of existing VMs. There is still lots of

Hey guys, I'm running the following setup on a few hosts: ~ # virsh version Compiled against library: libvir 0.9.8 Using library: libvir 0.9.8 Using API: QEMU 0.9.8 Running hypervisor: QEMU 1.0.0 Online Migrations with local storage are working smooth, Host OS is always Ubuntu 12.04, CPUs are Intel E3-1245 V2, 32GB Ram. Now I installed the same software on different hardware: Intel E5-2620,

Hello, I`ve found that the currently end-user may not migrate a VM between nodes with different security_require_confined, what are reasons to forbid such a thing? The security measures are almost not applicable here - if the guest was able to poison the emulator` stack on an unsecured node, he may do the same on a secured one, though the potential consequences will be far more limited. Are there

Has this been solved? Is there a bug report I can follow?

I am try using 11.0 on Dual E5-2620 (no X2APIC). Under high network load and may be addtional conditional system go to unresponsible state -- no reaction to network and console (USB IPMI emulation). INVARIANTS give to high overhad. Is this exist some way to debug this?

Hi, There is a quite annoying thing, don`t sure if I can call it a bug. How to reproduce: - start a bunch of VMs, - stop libvirt, - start libvirt and immediately issue any call, say, 'virsh version', - delay until call completion may be fitted nearly as quadratic function from number of running VMs, qemu-kvm in my case (see link below). After this delay passed, any calls executed

Hi folks, Firstly; apologies in advance for what is a head wrecker of keeping on top of the speculative mitigations and also if this is a duplicate email; my first copy didn't seem to make it into the archive. Also a disclaimer that I may have misunderstood elements of the below but please bear with me. I write this hoping to find out a bit more about the state of the relevant kernel

This might be related to the configuration of the virtual machine. A machine configured to have cpu X might not start up when it is changed to cpu Y. We also observed that a windows host does not boot on a ubuntu host with the default kvm configuration.
