i'm trying to get even the simplest busybox container with libvirt+LXC with very limited success. I feel l am missing something supremely simple for me to be hung on this for weeks.
i dont see anything interesting in domain log, but getting this error from "LIBVIRT_DEBUG=1 libvirtd":

i've been using this root filesystem layout:
[root@PHS-001 arch-nano]# tree . |-- bin | |-- cat -> ../sbin/busybox | |-- chdir -> ../sbin/busybox | |-- chmod -> ../sbin/busybox | |-- ls -> ../sbin/busybox | |-- rm -> ../sbin/busybox | |-- sh -> ../sbin/busybox | `-- vi -> ../sbin/busybox |-- dev | `-- pts |-- etc |-- proc |-- sbin | |-- busybox | `-- init -> busybox `-- sys
all folders besides /bin and /sbin were created by libvirt. i tried using the /sbin/init script previously suggested:
#!/sbin/busybox sh
Sorry, my suggestion was wrong. I forgot that if you have #!/sbin/busybox it will attempt to execute the command matching the name of the script. So it will in fact try to run 'init', rather than 'sh'. Just make the libvirt XML point directly to /bin/sh instead and it should work. I even tested it this time :-)
but i get a similar results either way (script/symlink):
8173 ? Ss 0:00 /usr/lib/libvirt-git/libvirt_lxc --name arch-nano --console 11 --background 8175 pts/0 Ss+ 0:00 init 8177 ? Ss 0:00 init 8181 ? Zs 0:00 [init] <defunct> 8182 ? Zs 0:00 [init] <defunct> 8183 ? Zs 0:00 [init] <defunct>
Yeah this is what I see too, when i have /sbin/init - changing it to /bin/sh works Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
