It shouldn't break thinks. But try it out.
And thanks for testing and reporting. :)
From the README:
http://git.qubes-os.org/?p=qubes-r2/antievilmaid.git;a=blob;f=README
Start the TCG Core Services Daemon:
[dom0]$ sudo systemctl start tcsd
If no service is recognized, install it (dependencies for AEM):
[dom0]$ sudo qubes.dom0-update tboot tpm-tools
For testing try it without AEM, otherwise:
[dom0]$ sudo qubes.dom0-update anti-evil-maid
Report the status of this daemon:
[dom0]$ sudo systemctl status tcsd
or
Display the output from the Platform Configuration Registers:
[dom0]$ find /sys/devices -name pcrs
[dom0]$ cat <path_to_pcrs>
or
Look into the logs:
[dom0]$ sudo journalctl -xn
and report lines with tcsd like this one:
$DATE dom0 tcsd[1234]: TCSD TDDL[1234]: TrouSerS ERROR: Could not find
a device to open!
$DATE dom0 systemd[1]: tcsd.service: control process exited,
code=exited status=137
$DATE dom0 systemd[1]: Failed to start TCG Core Services Daemon.
$DATE dom0 systemd[1]: Unit tcsd.service entered failed state.
It would be nice to pipe (>) the output into a file and attach these files
for Zrubi.

He is going to implement this in the qubes-hcl-report.
[dom0]$ sudo systemctl status tcsd > tcsd-service.txt
[dom0]$ cat `find /sys/devices -name pcrs` > pcrs.txt
Then copy them from dom0 to your destinationvm:
