Re: [lxc-users] Strange freezes with btrfs backend

2016-12-02 Thread Ingo Baab 

Hi Sergiusz,

 I am using a vm running ubuntu 16.04 with ~6GB Ram utilizing ZFS as 
loopback running multiple containers
(multiple wordpress containers and one mailserver container.. What do 
you suggest as minimum Ram

requirement for using ZFS?

Thank you
Ingo

With 1GB of memory is is not recommended to use ZFS not BTRFS,

[lxc-users] How to set lxc.network.ipv4/hwaddr/ipv4.gateway=auto in LXD 2.6 managed container?

2016-12-02 Thread Mateusz Korniak 
I am trying to move from LXC 1.1.x (macvlan) [1] containers to recent LXD [2].

I am stuck with problem:
- how can I set static ipv4/hwaddr and ipv4.gateway=auto?

I switched default profile to maclvan [3].
I created test container:

# lxc init ubuntu:16.04  ubuntu-1604-macvlan-test

Starting it confirms that macvlan iface works. Disbled DHCP configuration of 
eth0@if2, and now setting IP# fails:

# lxc config device set ubuntu-1604-macvlan-test virt ipv4.address 10.30.3.205 
error: The device doesn't exist

It's confusing as virt device is visible in lxc config show [4], but not in 
lxc config device list ubuntu-1604-macvlan-test [5]?

TIA, regards,


[1]: Old LXC network config
lxc.network.type = macvlan
lxc.network.macvlan.mode = bridge
lxc.network.hwaddr = 00:16:3e:00:31:12  


   
lxc.network.ipv4 = 10.30.3.112/23   


   
lxc.network.ipv4.gateway = auto

lxc-2.0.6
