Hi, I am currently having an issue with the libvirt_lxc binary that is launched when starting a lxc instance using libvirt. This process seems to have its own namespace for mounts. What happens is that if I umount something in the global namespace, it stays mounted in the libvirt_lxc namespace. I'm working with drbd, and after unmounting the mount p...

Hi, I have a libvirt_lxc system container (with systemd). After running "reboot -f" inside the container, I get "Rebooting.\n". htop shows that the libvirt_lxc and all subprocesses are stopped, but from libvirt api/virsh/virt-manager, the domain is still "running". So it looks like libvirtd...

...hout writing a config for systemd. I can't prevent memory.limit_in_bytes changing by setting the correct value through systemctl set-property --runtime <scope> MemoryLimit= tasks in the memory cgroup gets cleaned up. After starting the container the cgroup contains 3 pid. The pid of the libvirt_lxc process, the pid of the init process in the container and third unknown pid that doesn't exists in /proc/. After a demon-reload only the init process  remains in the cgroup and unless I move the libvirt_lxc process into the cgroup the memory limit isn't enforced. I have also noticed that...

Hello. Is it possible to start container via libvirt_lxc without mounting /sys inside container? When I start container via lxc-start and do not add mount point to config, then /sys inside container is empty. When I do it via virsh -c lxc:// container.xml, then /sys contains sysfs of the host and /sys on host becomes remounting read-only. Am I doing...

Hi , Is there anyway to get uuid info inside a lxc container which is created by libvirt_lxc? For kvm, we can use dmidecode or lshw to get this info inside vm. Is there any tools to do this thing for libvirt lxc? Thanks for any help~ -- ------------ Jackie Best Regards
