[vpsFree.cz: community-list] LXC kontejnery

[Vašek Chalupníček]

Ahoj,

rad bych si pohral s lxc kontejnery, ale koncim na chybach cgroup, zkousel
jsem se taky inspirovat v navodu na docker, ale neuspesne.

Nemate prosim nekdo radu, jak na to? Zkousel jsem Ubuntu 14.04 a Debian 8.
Je vubec mozne lxc na vpsfree vyuzivat?


cisty ubuntu trusty:

# lxc-start -n trusty
lxc-start: cgfs.c: cgfs_init: 2246 cgroupfs failed to detect cgroup metadata
lxc-start: start.c: lxc_spawn: 884 failed initializing cgroup support
lxc-start: start.c: __lxc_start: 1121 failed to spawn 'trusty'
...


po pridani mountpointu z navodu na docker:

# lxc-start -n trusty
lxc-start: cgfs.c: lxc_cgroupfs_create: 841 Could not find writable mount
point for cgroup hierarchy 2 while trying to create cgroup.
lxc-start: cgfs.c: cgroup_rmdir: 207 Device or resource busy -

cgroup_rmdir: failed to delete /sys/fs/cgroup/cpu,cpuacct,cpuset/
lxc-start: start.c: lxc_spawn: 891 failed creating cgroups
...


na cistem debian8:

# lxc-start -n debian8
lxc-start: Could not find writable mount point for cgroup hierarchy 4 while
trying to create cgroup.

/sys/fs/cgroup/memory/
lxc-start: Read-only file system - cgroup_rmdir: failed to delete

lxc-start: failed creating cgroups
...
