Unable to install Parallels Tools on Linux kernel 5.10

MikhailB · Jan 7, 2021

I am using Parallels for a while for managing Linux VM on my mac. Recently I tried to install a Linux instance with a new Linux 5.10. The installation itself went smooth and everything works as expected, except Parallels Tools, which I need to have shared clipboard on my mac and linux. Is there a way to fix this issue?
The root cause of the issues is the breaking changes in new kernel probably. I see the following errors:

Code:

I've the same problem with Manjaro distr and kernel 5.10.2-2. Thnaks

Mark Fine · Jan 12, 2021

Look at the patch for 5.9

SimoneG3 · Jan 13, 2021

Thanks a lot all is now ok, I've patched manually.
thanks

MikhailB · Jan 13, 2021

Indeed it works. Thanks, Mark!

MikhailB · Jan 15, 2021

@Mark Fine appears that after successful install, still shared clipboard does not work and there is no mounts either. Checked multiple places, but found no errors anywhere. Could you please suggest how to troubleshoot?
I am running Arch Linux 5.10.6.

Mark Fine · Jan 15, 2021

According to post somewhere the clipboard issue might be related to Wayland. I think to get around that don't use the regular Gnome setting when logging in. Try using "Gnome Classic" or "Gnome on Xorg". The shared mounts might be related.

Regarding the patch this made my Fedora 30 (Kernel 5.10) under Mac (Host 10.15.7) working.
Please note that the parallel tool compilation worked, so I have now shared folders etc., but coherency did not work. Actually, I'm wondering how Parallels can really want their users to follow such advanced machines, but maybe there are to little Linux users which suppoedly are all experts....

Procedure:
I used patch (5.9) for my Kernel (5.10) and followed this procudure here (Tools Patch Procedure)
https://forum.parallels.com/threads/tools-patch-procedure.351669/

Kernel Patch Downloaded from here:
https://forum.parallels.com/threads/tools-patch-procedure.351669/

My modifications were then for the kernel patch in step 9 of the decription:

a.) Modified Inode.c

#include <linux/slab.h>

#if LINUX_VERSION_CODE >= KERNEL_VERSION(5, 9, 0)
#include <linux/blkdev.h>
#endif

#include <asm/uaccess.h>

b.) Modified prl_freeze.c to:

bd->write = (write == 0) ? 0 : 1;
#if LINUX_VERSION_CODE >= KERNEL_VERSION(5, 9, 0)
bd->user = (user == 0) ? 0 : uaccess_kernel() ? 0 : 1;
#else
bd->user = (user == 0) ? 0 : segment_eq(get_fs(), USER_DS) ? 1 : 0;
#endif
bd->flags = TG_REQ_COMMON;

You might have the filenames reversed in a) and b) but it's good that you got it working. Congrats.

Hi Mark,

you are totally right, in my post the filenames are reversed....
