Okay, worked in that way that I'm still able to use qubes after the update and 
it eliminated the error line with the record truncated
>xc: error: X86_PV_VCPU_MSRS record truncated: length 8, min 9: Internal error

However, besides that my basic problem still persists in the exact same way. So 
I do get the same error from the screenshot above (exactly the same) when I try 
to start a dispVM and in the /var/log/libvirt/libxl/libxl-driver.log there are 
now the following 3 lines per try (instead of 4 before):
>xc: error: Restore failed (0 = Success): Internal error
>libxl: error: libxl_stream_read.c:749:libxl__xc_domain_restore_done: restoring 
>domain: Success
>libxl: error: libxl_create.c:1145:domcreate_rebuild_done: cannot (re-)build 
>domain: -3

I have tried deletion and recreation of the dispVM template several times as 
well as reboots. I also switched the dispVM template versions (fedora-23, 24 
and 25) but without luck.

I guess this is some progress but unfortunately dispVMs are still not working.

I have and after that qubes wasn't even able to boot 
(https://groups.google.com/forum/#!topic/qubes-users/Sr_C3cVTaG4) so I'm a 
little worried about that option. Is there way to update dom0 with an way to 
easily fallback in case it goes wrong again?

Although the bug still appears to be open it looks from the changelog
from Xen 4.9 that the issue with zero length records has been fixed.
Have you tried updating dom0?

I guess this could be the problem.

/var/log/libvirt/libxl/libxl-driver.log produces the following 4 lines for each 
try to start a disposable VM:

xc: error: X86_PV_VCPU_MSRS record truncated: length 8, min 9: Internal error
xc: error: Restore failed (0 = Success): Internal error
libxl: error: libxl_stream_read.c:749:libxl__xc_domain_restore_done: restoring 
domain: Success
libxl: error: libxl_create.c:1145:domcreate_rebuild_done: cannot (re-)build 
domain: -3

So I guess this means I'm out of luck here and no workaround available?

Have a look at /var/log/libvirt/libxl.
If, as I suspect, you see "record truncated", it's a long standing bug
in Xen: , Qubes issue is still open.
If you dont see that post the relevant sections of the log
