Dear list, I am bulding a VM using libvirt and lxc for linux container. I have an issue with my cgroups settings: gabx@hortensia ➤➤ ~ # virsh start dahlia error: Failed to start domain dahlia error: internal error: No valid cgroup for machine dahlia My environement: Host : Arch Linux - systemd 208-11, libvirt 1.2.1-4 guest : Arch Linux , machine name : dahlia , /etc/libvirt/lxc/dahlia.xml , mounted in /machine/dahlia My set up so far : - gabx@ho...

GGGrrhhh. I use the slice concept (or partition map) with this file : machine-dahlia.slice I have been reading and reading again your mentioned link, and I think it is the correct thing to do. But this part puzzles me: Systemd slice naming The systemd convention for slice naming is that a slice should include the name of all of its parents prepended on its own name. So for a lib...

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

...just beyond my competence. For now, I am writing a basic mydomain.xml file following these 3 wiki: LXC container from libvirt.org[1] Linux containers guide from Rad Hat 7[2] getting start with lxc from P.Berrange [3] This is the basic .xml file: <domain type='lxc'> <name>dahlia</name> <memory>409600</memory> <os> <type arch='x86_64'>exec</type> <init>/bin/init</init> * systemd is default and PID1 is init on my Arch box <vcpu>4</vcpu> </os>...

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>. Failed to verify GPT partition /dev/sdb1: No such file or directory /usr/lib/systemd/system- generators/systemd-gpt-auto-generator exited with exit status 1. # blkid /dev/sdb1: UUID="f69d032f-c80f-4f2e-84cd-d2328a862818"...

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 sentence, in bold, puzzles me: A suitably configured UID/GID mapping is a pre-requisite to maki...

Hi all, This is a Noob question but I couldn't find anything on the syntax page about making a link that opens in a hew window (and two years of email archives was too much). For eg. with "This is an [example link](http://example.com/)" where do I put target="_blank" or its equivalent so it opens in a new page? Any help would be greatly appreciated. Thx Tony
