More parsing
Fix regex
Improve --boot handling
Move readovf from manager to qemu-server (like CPU)
Create properties helper for readovf return values

still a few more comments inline - but this is taking up shape (and the

these two are basic sanity checks - they can only trigger if the code is 
wrong. the 'You' is this potentially misleading. also, typo in the 
second message ;)

format '$format', else this could read strange.

you misunderstood my comments here - I really meant

my ($storecfg, $vmid, $conf, $source, $target) = @_;

putting everything into a single param hash is usually a sign of "need 
to refactor this", and tricks you into thinking "bolting on 
yet-another-parameter is fine" ;)

this comment doesn't tell me anything. IF you really want, add a comment 
above abs_file_system_path like

# Check foo, bar and baz
abs_file_system_path

# Check storage exists
storage_config

file_size_info

please use parsed options (by passing them in from the call site instead 
of the plain string - currently, the same thing gets parsed again and 
again, which is not needed).

shouldn't this go higher up, e.g. in case adding the unused volume dies? 

also, if we mention both paths/volids in the "Importing ..." message, 
this can just become a single "Done" or "Success", directly after the 
actual import error handling?

so this might be written back to $device_options, makes the rest of the 
code more reliable/usable and allows us to only parse here once..

no need for this then, it's just $device_options->{format}

$conf is fine for this, and a simple

# quick checks before fork + lock

should be enough, it's a common pattern in our API2 modules..

should probably get a proper format, and this can then be a 

'device-image-mapping-list' or whatever fancy name you come up with ;)

\0-delimited might be a good idea - else you restrict what kind of paths 
can be imported.. (for CLI, the parameter can be passed multiple times 
to defined the list IIRC). ping me if you can't find an example for how 
to do this!

and if I want to create 10GB volume? note that we have a NEW_DISK_RE at 
the top of this module, maybe we want a IMPORT_DISK_RE next to it?

why not build the $param hashes directly, instead of indirectly via 
lists? e.g., you can just remove the import params and put them in a new 
hash, and keep $params for the rest?

avoid using $_ for such things please.

you define a helper above, but not use it here.. also, the check is 
wrong here as well ;) if you split the $import_params from $params above, 
then you can just check if $import_params->{$device} is defined, in 
which case you know it has the special import syntax.

here the question is - which parameter is wrong ;)

"device '$device' not marked for import, but import source '..'

same message as for the other branch, no comment needed. in fact, this 
could just be

die/raise_param_exc ..
  if (!defined($param->{$device}) || !$is_import->($param->{$device}));

altogether to replace both branches and the comment and the overly long 
messages. by splitting $params early, it then becomes

die/...
    if !defined($import_params{$device});

so if you extract the import_params instead of using a target_devices 
list, you can just map and grep here to compare $diskimages keys with 
$import_params keys.. no need to parse again and again

or if you want a loop:

foreach my $import_device (keys %$import_params) {
    die/raise_param_exc "device '$import_device' marked for import, but no source given\n"
      if !defined($diskimages->{$import_device});
}

why? could also go before, you don't even differentiate between import 
or create below? also, we don't have such a check when creating a VM, do 
we? just when updating. maybe it would make sense to unify the handling? 
this is not related to import at all, so could also be split out for a 
follow-up.

couldn't this go above then next to the bootdisk check?

reload_conf might be a better name

why? you don't update the config here? an flock is needed for *writing* 
the config (or *blocking writes* by others for a short period)..

this is a misleading name - this contains all the disks that are not 
imported, which can take a while (not as long as importing, but 
still..). and it's not needed if we split the import_params out of 
$params above anyway..

yeah, so this does an flock internally, but to guarantee it still is the 
right config you need to set the digest in $short_update.. same for 
other calls to update_vm_api - you reload the config, check your config 
lock is still there, then you have a valid digest to pass to 
update_vm_api, which obtains an flock (== no other writes possible), 
checks the digest (== no writes happened since our config reload before 
calling update_vm_api) and then does the config modification and write 
before releasing the flock. of course, now the digest and our $conf is 
invalid, so we need to reload (and now we have a digest again for the 
next call ;)).

at this point we'd need a proper VM removal - disks might have been 
allocated, and who knows what else..

can be fine - not 100% convinced yet that we need to treat this as 
separate from 'create' ;)

then maybe turn it around? it makes more sense to have a base format and 
then an extension IMHO. else now someone has to keep in mind that there 
is a filter here when updating the other format, which is easily 
missed..

-b $src_volid

the comment is not needed (and wrong) - '-b' already states that we 
check for block devices, and this is not LVM specific at all, it also 
handles direct references to zvols, mapped rbd images, physical disks, 
loopback devices, or, well, any other block device ;)

maybe something like $manifest_only - we might want to skip other 
futures stuff as well, not just reading the file size.

doesn't this already fail?

is 0 a good default here? wouldn't undef make more sense?

that's not how we name perl variables..

this could easily still be a single if:

    die "can't find file '$volid'\n"
      if !($path && -f $path) && !($path && $allow_block_dev && -b $path);

or some other transformation of the condition, like

  if !$path || !(-f $path || ($allow_block_dev && -b $path))

or

  if !($path && (-f $path || ($allow_block_dev && -b $path)))
