I am using Archlinux with virt-manager and kvm. When I conifgured like this and I got these errors below. Can somebody help me solve it? Thank you a lot!
Configration of Display Spice
Configration of Video Virtio

And I found these in /var/log/libvirt/qemu/$MYGUESTNAME.log, but I cannot figure out what's wrong with it.

That is a sign that QEMU has unexpectedly crashed. if you are lucky there will be more useful error information in /var/log/libvirt/qemu/$GUESTNAME.log that will help you diagnose the problem
Does anyone know of a "FREE" command line tool that can lock a pdf from a user being able to print it. I need to be able to put this in a batch to loop through a folder and disable printing from adobe standard and reader. Is this possible to do it from command line with any tool?
First, pdftk:
You can use pdftk for (available for Linux, Unix, Mac OS X and Windows) to set an "owner password":
pdftk \
input.pdf \
output semi-protected.pdf \
owner_pw "supersecret"
Result is this, for example:
pdfinfo semi-protected.pdf | grep Encrypted:
Encrypted: yes (print:no copy:no change:no addNotes:no)
You can modify the command to additionally require a user password to open the PDF:
pdftk \
input.pdf \
output semi-semi-protected.pdf \
owner_pw "supers3cr3t" \
user_pw "s3cr3t"
You can modify the command to (selectively) "allow" other user actions:
pdftk \
input.pdf \
output semi-semi-protected.pdf \
owner_pw "supers3cr3t" \
allow ModifyContents \
allow CopyContents \
allow ScreenReaders \
allow ModifyAnnotations
Result may be this, for example:
pdfinfo semi-semi-protected.pdf | grep Encrypted:
Encrypted: yes (print:no copy:yes change:yes addNotes:yes)
Second, podofoencrypt:
Commandline example:
podofoencrypt \
--rc4v2 \
-o "supers3cr3t" \
-u "s3cr3t" \
--edit \
--copy \
--editnotes \
--fillandsign \
--accessible \
--assemble \
input.pdf \
semi-protected.pdf
Big, fat caveat:
You should be aware, that this way of 'protecting' PDF files is by no means super-secure. There are quite a lot of PDF cracker software utilities out there which easily un-protect your PDF files. This method is only a very basic means to prevent most noobie computer users to mess with your files.

Third, qpdf:
in Martin Schröder's answer!
qpdf can do this:
qpdf \
--encrypt \
"user-password" \
"owner-password" \
40 \
--print=n \
-- \
infilename \
outfilename
or even
qpdf \
--encrypt \
"user-password" \
"owner-password" \
128 \
--print=non \
--accessiblity=y \
--force-V4 \
--modify=form \
-- \
infilename \
outfilename
