libvirt 経由で lxc を触ろうと思いハマる (2)
前回 は iproute2 のバージョンのおかげで define が出来なかった libvirt 経由の lxc ですが，次に新たな問題が．
- 定義ファイルを libvirt: LXC container driver を参考に作成．
debian
32768
exe
/sbin/init
1
destroy
restart
destroy
/usr/libexec/libvirt_lxc
- define
# virsh --connect lxc:/// define debian.xml
- start は成功する．
# virsh --connect lxc:/// start debian
Domain debian started
start は成功するものの...
- console に接続しようとしてもだんまり．
- ping は通る．
- sshd とか起動している風なし．
- xinetd と cron と sendmail は起動しているっぽい．
- getty はダメっぽい．

ググってたらこんなの見つけた... (;_;)

AFAIK libvirt still doesn't support /sbin/init as the init program.
In my case, I write up and use a script of 'fake' init which sets up
inside a container, e.g., assigning IP addresses, launching sshd,
etc. The script eventually 'exec /bin/bash', then the shell is shown
via virsh console. That's enough for my purpose.: (snip) https://www.redhat.com/archives/libvirt-users/2010-August/msg00005.html
Note that libvirt lxc driver is a different implementation from lxc tools
and doesn't use lxc tools internally. You may not be able to do what
you are doing with lxc tools. Especially, the driver doesn't take aware
of files and settings inside a container at all. You have to prepare them
by yourself in advance.
