bug#64073: libvirtd requires restart to function

[Christian Miller]

Hello,

I tested your patch and it works.  With the patch virt-manager does instantly 
connect without any manual interference.

Since this is the first time I did this, just to be sure I did everything 
correctly, I list how I tested it.

I cloned the git repository
I created a file called libvirtd.patch with your contents
git apply libvirtd.patch
guix shell -D guix --pure
./bootstrap
./configure --localstatedir=/var
make
make check (had 2 errors, authenticate and something else)
after that I executed "sudo -E ./pre-inst-env guix system reconfigure 
~/guix/system.cm"
I rebooted the system and launched virt-manager which directly connected.

Best Regards,
Christian Miller
