Dear list, I am bulding a VM using libvirt and lxc for linux container.

Dear all, I am slowly building a Arch Linux VM guest on my Arch Linux host. The guest machine is now built and is recognized as shown by this command : gabx@hortensia ➤➤ ~ % machinectl list MACHINE CONTAINER SERVICE dahlia container nspawn 1 machines listed. I an following the libvirt.org documentation. Now, according this page[1] about lxc driver, i am dealing with namespace requirements. This sente...

I must add I can boot the container this way : gabx@hortensia ➤➤ ~ # systemd-nspawn -bD /machine/dahlia A few error messages at boot : Set hostname to <dahlia>.

...es or containers created by libvirt will be associated with machine.slice by default. Following above lines, I am thus not sure of the correct name of my .slice systemd file. When trying to avoid any issue, the guest is on the root of my filesystem in /dhalia. directory. This directory is owned by gabx:qemu (not sure it is useful, but when I created it, it came with these owners)

This directory is > owned by gabx:qemu (not sure it is useful, but when I created it, it > came with these owners) Lets say you want a 2 level hierarchy for the guest from your example above. In the libvirt XML you would set the partition name to: /machine/dahlia this corresponds to a systemd slice call machine-dahlia.sli...

USE_NETWORK=1 command and USE_NETWORK=1 command have quite different effects in bash. Anyway an easier way to do that is to: ./configure --disable-network-tests Rich. -- Richard Jo...

Dear list, I am building a Arch server on my Arch box. My tools are QEMU/KVM and libvirt to manage the guest, systemd as system manager. I am looking at implementing the Linux Control Groups facilities for resource management. Even after long hours of reading, I am not quite sure about how to deal with the cgroups facilities. First, do I really need to care about all that, or libvirt and
