Hi,
i'm trying to test the lxc support in libvirt, but but libvirt failed to
start container with error "lxcContainerAvailable:897 : clone call
returned Operation not permitted, container support is not enabled"
What's the kernel version you use? Just as the error message says, the
system call 'clone' failed, It's probly caused by lacking of kernel
support.
At least you should make sure 'clone' support these flags:
CLONE_NEWPID, CLONE_NEWNS, CLONE_NEWUTS, CLONE_NEWIPC, SIGCHLD
- Osier
Althought i've compiled libvirt with th lxc support:
