Hi all,
the systemd shutdown scripts work sequentially with a 300s timeout
(seen on Debian). If a VM does not have ACPI support, or the ACPI
support failed for some reason, you are looking at a 300s timeout per
instance for a host shutdown/reboot.
i.e. 10 instances without working ACPI = 3000s to
Hi all,
the shellscript causing VMs to eventually stop when the host shuts
down/reboots has a window where it can loose ACPI shutdown events.
I have seen VMs not shutting down before they become ACPI aware,
causing the systemd magic to time out for a couple of minutes and
eventually killing the V

Hey,
i am running an unusual setup where i assign pci devices behind the
back of libvirt. I have two options to do that:
1. a wrapper script for qemu that takes care of suid-root and appends
arguments for pci-assign
2. virsh qemu-monitor-command ... 'device_add pci-assign...'

Use virCgroupAddTaskController in virCgroupAddTask so we have one

Move qemuProcessSetupEmulator up under qemuSetupCgroup. That way
we move the one main thread right into the emulator cgroup, instead
of moving multiple threads later on. And we do not actually want any
threads running in the parent cgroups (cpu cpuacct cpuset).

Moving tasks to cgroups implied sched_setaffinity. Changing the cpus in
a set implies the same for all tasks in the group.
The old code put the the thread into the cpuset inherited from the
machine cgroup, which allowed it to run outside of vcpupin for a short
while.

Hi,
i am currently looking into realtime VMs using libvirt. My first
starting point was reserving a couple of cores using isolcpus and later
tuning the affinity to place my vcpus on the reserved pcpus.
My first observation was that libvirt ignores isolcpus. Affinity masks
