Extract files from ploop disk image

Question

I have ploop disk image created by dumping an OpenVZ container. There are two files:

791     DiskDescriptor.xml
2.4G    root.hdd

Is there any way to extract the whole root file system from there on a non-OpenVZ machine?

You don't need to spin up the container, you can simply mount the filesystem image according the manual https://openvz.org/Man/ploop.8

ploop mount
[-r] [-F] [-d device] [-m mount_point] [-o mount_options] [-t fstype] [-u uuid] DiskDescriptor.xml

Thanks, but it appears that `ploop` works on OpenVZ hosts only. On Ubuntu 15.10 I am getting `Error in ploop_getdevice (ploop.c:874): Can't open /proc/vz/ploop_minor`. I've edited the question so that it is clear no OpenVZ available. – Greendrake Apr 15 '16 at 23:02
