Hello,
I've just started using OpenVZ, and it feels more natural than the
alternatives I've seen -- my compliments!
I can get a host runnig from a ZFS volume like /tank/vzdemo, which then
also gets shown at /var/lib/vz/vz-$VEID. But what I really want to
do is use a layered FS (like aufs) as the private directory for the
container. But trying to do that leads to an error:
bash# mount -t aufs -o br:/tank/vzdemo=rw:/tank/squeeze=ro none /mnt
bash# grep VE_ /etc/vz/conf/777.conf
VE_PRIVATE=/mnt
bash# vzctl create 777
Private area already exists in /mnt
Creation of container private area failed
What is this trying to say? Is there a way to do what I am trying
to do? Did I understand well that the private area is a directory,
not a device?
Thanks,
-Rick
P.S. To capture any "why" questions :- I am trying to share as many
resources as possible. Containers beat Xen/KVM/VMware in that
respect, and when I can share the base OS and only have a thin
layer on top, it should mean that even the buffer cache is
shared between containers. It also means that upgrades can be
reduced to a minimum of repetition.
