Hi,

some update to my problem here:

The profile directory of my normal user account is located on a network
share. I can successfully copy files from this win7 hvm to other vms.
But in the other direction it is not working. I found those lines in the
qrexec-agent log file (log level 4):

I have already tried to create a new user with a local profile dir. This
one works as expected.
So it seems qrexec-agent somehow does not like the network share.
Is there any possibility to change the destination directory for
qvm-copy-to-vm operations?

regards,
hansi

Correct, if a user profile is in a mapped directory it will cause issues
with the way qvm-copy works. Currently there is no way to change the
destination, but adding such configuration option seems like a
reasonable idea.
