Ok, after some research my conclusion is:
you can't see side-car files in Lightroom
and also that
Lightroom does not really support a RAW+JPEG workflow
By RAW+JPEG workflow I meant being able to:
(at the user's discretion) Review both files together, while being able to tag both files at once (say, mark both files as Rejected with a single command).
It is not currently possible to either save multiple .XMP files per image nor to save multiple versions of settings in a single .XMP file. Here are a couple workarounds:
Instead of creating a virtual copy, make one set of adjustments and save a snapshot in the Develop module, then go on and make the other set of adjustments. This is kind of clunky, but ...
As far as I know, there is currently no way to translate PP3 to XMP sidecars, or vice versa.
And developers are often reluctant to adapt their program to read data written by another program, especially for formats like .PP3, which can change without warning between program versions*.
Even exchanging XMP files from different programs isn't all that evident....
It's a repository of *.dtstyle files, not XMP files... those are generally used for file-specific information. Styles can be managed in the "Styles" panel on the right-hand side in lighttable mode.
there is a second, potentially better, method that i have found.
on your original file, save snapshot "original"
on your virtual copy, save snapshot "virtual copy"
"save metadata to file" on your original file
the xmp will contain 2 snapshots. one of your original, one for your virtual copy.
open up the linked xmp file in a text editor and you ...
The only way possible that I know of is to do the following workaround:-
create a smart collection using "copy name" - "is not empty"
this will create a smart collection of all your virtual copies
export using "file format" "original"
choose a folder for your exported files, or use "same folder as original image".
you may want to put the virtual copies in ...
No, I don't think that it is supported. I'm not sure though if it is generally possbile.
To find out the truth, we need to look at different Specifications.

This documentation states, that Lightroom ...
XMP files do not contain references to the original image file, so in principle, it is possible to use the same XMP file for multiple images with different extensions.
ExifTool does not normally "overwrite" files. When updating a file, it creates new tags and changes preexisting tags, as needed. Preexisting tags in the destination that are not in the source ...
At your step 5., when you export a RAW file from LR to PS (or when you open a RAW file with PS, make some editing and then save it in TIFF format and import it back to LR), a TIFF get created. However, this TIFF has no sidecar file attached, so you won't find any.
So back in LR with a TIFF file, you expect the changes you made to be saved in a XMP file... ...
Actually, none of these answers point directly to a workable solution.
Firstly, ensure that the following preference option is selected :
Edit > Preferences > General > "Treat JPEG files next to RAW files as separate photos"
Now, irrespective of whether you immediately try to search for your JPEGs or after you close and reopen the application to search ...
My assumption is that the virtual copy and its associated develop settings are important because this is now your favorite version of the image. The workaround I believe is pretty simple in this case. Instead of having this virtual copy, simply switch it to a Master Copy.
In the Library module, select a virtual copy of another photo.
Choose Photo > Set ...
May I suggest you to use our Daminion as a workaround to transfer your metadata from sidecar xmp files:
1. Import your JPEG files into Daminion.
The program will import your changes from sidecar files (it will check each file and compare modified date of an original JPEG with its sidecar xmp file)
2. Select all the imported files and select Action > Write ...
