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

Hello, I think it would be useful if libvirt will be able to prefix all messages from emulator pipes with the date stamping, for example I am trying to catch very rare and non-fatal race with virtio-serial-bus: Guest failure in adding device virtio-serial0.0 which is specific to the Windows guests on qemu-kvm. I have supporting infrastructure which can tell me exact times for every action upon

Hi, please see following backtrace. How to reproduce: start qemu guest w/attached console, execute migration, get a crash at the end.

Hi, At least on 0.10.2 setting a cpuset doesn`t match a real process placement - VM still consumes all available cores.

Hello. Is that possible to create virtio-serial port that on host listens tcp socket and how to avoid duplicate listened ports in case of migration? -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru

Hi, Netperf tells me that a KVM VM using a bridged connection to a system across the Gigabit LAN sees on average about 1/10th of the bandwidth the host sees. This is on very lightly loaded hosts, although with multiple low-use VMs. I've tried adjusting the CPU throttling after seeing that mentioned as a possible factor in slowing down a bridge, but it has not much if any effect here. Is

Hey folks, I am running libvirt 1.2.4 and qemu 2.1 on a 3.14.27 kernel. I've found that live migrating a relatively large VM (16 cores and 64G ram) is taking forever - close to 15 hours now, and still not done... With "lsof -i", I can see a connection is established from my source hypervisor to a target hypervisor, likely for the purpose of copying data. nettop shows that this
