Is there currently a command to retrieve information about the contents of a VZDump backup file? The only things encoded in the filename itself are the VM number and the date/time the backup was done. It would be nice to be able to show the attribute/value pairs shown in the options tab of the GUI, at very least the name of the VM. If no such utility exists, perhaps someone would comment on where I might start to look at the source code, or where the format of these backup files is documented.

- Start date
Thanks Tom, that puts me on the right track, at least. I noticed there is no man page for the vma command (I'm not complaining, since I firmly believe that complaining is equivalent to volunteering
. I do have a couple of questions about the command. If I type vma with no arguments, it prints a usage message:usage: vma command [command options]
vma list <filename>
vma config <filename> [-c config]
vma create <filename> [-c config] pathname ...
vma extract <filename> [-r <fifo>] <targetdir>
vma verify <filename> [-v]
For posterity, and in lieu of the aforementioned missing man page when someone writes it, perhaps someone could correct me and/or expound upon the following explanations:
Note that in the following, it is necessary that the file corresponding to <filename> not be compressed. So, if you have a file vzdump-qemu-202-2015_01_19-00_00_01.vma.gz, you must first run gunzip vzdump-qemu-202-2015_01_19-00_00_01.vma.gz to uncompress the file into vzdump-qemu-202-2015_01_19-00_00_01.vma, which will then be the value that you will use for <filename> in the following.
vma list <filename> lists the contents of the given file. In my example case, the command prints the following:
CFG: size: 361 name: qemu-server.conf
DEV: dev_id=1 size: 10737418240 devname: drive-virtio0
CTIME: Mon Jan 19 00:00:01 2015
vma config <filename> [-c config-file] prints the contents of the VM config file (e.g. qemu-server.conf). For example:
balloon: 1024
bootdisk: virtio0
cores: 1
ide2: local:iso/ubuntu-14.04-server-amd64.iso,media=cdrom
memory: 8192
name: OpenEMR
net0: e1000=26:BE:8D:CE:F4:83,bridge=vmbr1
onboot: 1
ostype: l26
smbios1: uuid=eec937fb-1c70-40c9-a958-e52345a6c8a7
sockets: 1
virtio0: local:202/vm-202-disk-1.qcow2,format=qcow2,size=10G
#qmdump#map:virtio0:drive-virtio0:local:qcow2:
Am I right to guess that if I pass -c config-file, it will replace the contents of the config file with the contents of the passed file name?
I don't know enough at this point to speculate on the details of how the create, extract, and verify commands work.
