Fail to build kernel modules on Linux kernel v4.15+

Sure enough:
1. Made the code changes in /usr/src/parallels-tools-13.3.0.43321/prl_fs_freeze/Snapshot/Guest/Linux/prl_freeze/prl_fs_freeze.c
2. Gzipped a new prl_mods.tar.gz
3. Carefully updated to kernel 4.16.7 (so as not to lose the grub entry for 4.14.x)
4. Rebooted into 4.16.7 and it works.
I cannot believe that for a few short lines of workaround code, we've not had a Tools update to fix this since February 21st... exactly 3 months ago.

Just did this after upgrading the distro to 18.04 LTS (kernel 4.15.0-22-lowlatency, e.g. Ubuntu Studio) and it worked great.
Thanks to the poster that supplied the workaround!
Parallels, now that someone did your research for you (or most of it - how to get the module built despite the license issue is yours to solve, I gather, although this can't be the first case where that came up), I really see little excuse for further delay.

 

What a coincidence...

 

Given the kernel fix I attempted to try an upgrade from Fedora 26 to 27. All packages downloaded, and installs began without a hitch after rebooting.
However, because of hotfixing the install re-rebooted somewhere around package 575 of 2730: after several critical packages were updated, and before 4.16.9-200 kernel was fully installed. The re-reboot gets to a point where the incompatibilities fail (ABRT, etc.), finally waiting for a Parallels Tools reinstall that either fails or never occurs.
As a result, there's no way to Cmd-F2 into anything to fix it, and I've just wasted 2.7GB downloading a failed install.

Yes, before a mod says it, Fedora 27 is not yet supported in Parallels Tools 13.3.1.
I know this. Just putting it out as a warning to anyone else that tries that you may be wasting your time, even though 26 will be EOL soon (if not already), and 28 was released on 1 May. Note that Fedora only currently supports 27 and 28, as stated on their release schedule.
Given that Fedora releases are every May and Oct, this is now an untenable situation trying to keep up with Parallels.

 

You don't really resolve my issue for my and others' Guest OSes, from my prospective. See another post of mine https://forum.parallels.com/threads...ble-latest-13-3-1-43365-fixes-nothing.344639/

 

Was unable to upgrade F26 using dnf system-update or doing a direct update using the packages downloaded from that using dnf or rpm. Each time it create a kernel oops at some random mid-point during the package loading phase. Although, I did manage to get near package# 1450 of 2610 once.

Gave up that process and tried a Fedora 28 LiveCD clean install, which worked. After getting the root password changed was also able to install Parallels Tools (on kernel 4.16.11-300), get internet working, and update the minimally installed baseline. Now just have to go through the suboptimal process of moving settings/data over, and install packages and repositories for apps I had been updating since F21. #joy

 

with 4.17 kernel and parallels 13.3.1 not work anymore

 

Just DNF'd to 4.17.11 using Parallels 13.3.2 (43368) with no issues.
