I recently encountered a situation where an unclean ebtables shutdown
caused /var/lib/ebtables/lock to be left behind. When libvirtd was
started on such a system, it caused libvirtd to hang. Reason:
While probing to check if locking was supported, libvirt runs this
command synchronously :
#
Ploop is a pseudo device which makes possible to access
to an image in a file via block device, like loop devices,
but with additional features: snapshots, write tracker
and without double-caching.
It used in PCS for containers and in OpenVZ. You can manage
ploop devices and images with ploop
This patch series adds ability to manage container's
filesystems: you can add or remove fs from existing
container or create new one, based on existing
disk image.
Dmitry Guryanov (5):
add ploop fs driver type
parallels: dump info about container filesystems
parallels: commit with
Handle information about filesystems in domain config
and add corresponding devices to container via
parallels sdk.

PCS removes disk image from filesystem, if you remove it
from config. There is a special flag PVCF_DETACH_HDD_BUNDLE

If you call virDomainDefine and remove some disk from
config it should be preserved, so call PrlVm_CommitEx
always with flag
Obtain information about container's filesystems and
store it in virDomainDef structure.

It's possible to create a container with existing
disk image as root filesystem. You need to remove
existing disks from PCS VM config and then add a new
one, pointing to your image. And then call PrlVm_RegEx
with PRNVM_PRESERVE_DISK flag.
With this patch you can create a container with the
