Well, I got around this now.
After even more trial and error since last time writing here, I skipped trying to get 1.04b loader to work even though i got that far.
I found out that I could get it to recognize the virtual HDD if i used the 1.03b loader instead.
But ONLY if i used the ds3617xs version.
ds3615xs did not work for me at all. Could'n get it to be found on the network.
DS3617xs could though.
So after booting up on loader 1.03b with version ds3617xs and ofc renamed the NIC interface to 'e1000' in the XML editor.
I got to the part where I should set it up.
At 1st I tried to install automaticly from the synology site with the latest patch/firmware (DSM 6.2.1 version 23824).
This ended up not booting anymore. So that obviously did'n work.
Then I tried installing the previously version (version 6.2 23739) and that booted.
As of now, I am stuck there when it comes to updates, but it's booting and working. and imo it's a pretty nice enhancement to unRAID to have DSM on top.
I even only allocated 512mb ram to it and there is no problem what so ever.
Hope you get it working
btw, I found it not to get online if I booted it as VMWARE mode or what it is called. I got it working via the BAREMETAL option.
I uploaded my synoboot.img to MEGA without my serial and mac address in it. if you want to try if it works for you.
If you need to get a serial for it, use this link: Serial Generator for XPEnology
If you need the .pat file i used, use this link: DS3617XS version 23739 DSM 6.2
If you want my Synoboot.img use this link: synoboot.img file 1.03b for DS3617xs
