Adapt "nova resize" code to support Virtuozzo ploop disks. As far as ploop disks are in fact directories we add '-r' argument to all utilities that deal with instance' disks such as cp, rsync and scp. Thus we copy disks universally whether they are folders or files. Also using "prl_disk_tool" instead of "qemu-img" is better for ploop images because it resizes guest filesystem as well. We can't resize disks from guest OS in containers, because they are not allowed to write directly to block device. ploop tool can resize partition table and internal filesystem, but only for container's disks. Such disks must have only one partition with ext filesystem. prl_disk_tool can resize disks with internal filesystems and doesn't require any special layout so it can resize disks for virtual machines. So it's better to use this tool instead of ploop. Also we make compute.filters more strict We call "ploop" only with "restore-descriptor" argument And we set disk size in megabytes for prl_disk_tool Co-Authored-By: Dmitry Guryanov <dguryanov@parallels.com> Depends-On: I04c4379459c2fc1fd4801ec2aad53d0f6053b6d6 Change-Id: I38dbf73beb01fe1939ddca63fbfedbec1dc3c826 Implements: blueprint virtuozzo-instance-resize-support |
