fedora 22 filesharing problem with virt-manager and Windows 7 guest

edit

I'm running Fedora 22 (64 bit, 16gb memory) with a cinnamon desktop and I would like to use Virtual Machine Manager to run Windows 7. However, I need filesharing between the Fedora 22 host and the virtual machine (Windows 7). I installed samba and Virtual Machine Manager via

sudo dnf install system-config-samba
sudo dnf install virt-manager

I then created the /mnt/disk1 (with 1 file) and /myshareddisk1 (empty) directories and used chmod 777 on both of them. Then I added the following trailer to /etc/samba/smb.conf:

[mydisk1]
comment = My Disk1
path = /mnt/disk1
public = yes
writeable = yes 

Then I used the following commands to enable the samba access to /mnt/disk1.

semanage fcontext -a -t samba_share_t "/mnt/disk1(/.*)?"
restorecon -R -v /mnt/disk1

Then, I used the following commands to create samba passwords for the root user, and my other user, steve.

smbpasswd -a root
smbpasswd -a steve

I then started samba and made /myshareddisk1 a mount of /mnt/disk1 via

systemctl start smb
mount //localhost/mydisk1 /myshareddisk1 -o user=steve

I then verified the samba process via both

smbclient -U steve -L localhost
ls /myshareddisk1 : the /mnt/disk1 file was displayed.

I then started the virtual machine service (systemctl start libvirtd) and started the virt-mgr application. Then I created a new virtual machine, and used a Windows 7 iso to install Windows 7 into this machine. The Windows 7 virtual machine runs ok.

SO FAR, EVERYTHING WAS FINE. HOWEVER THIS IS ALL WORTHLESS TO ME IF I CAN'T FILE SHARE BETWEEN FEDORA AND WINDOWS.

Using the virt-mgr gui, I tried to add a samba file system to the Windows 7 virtual machine; an error message was generated.

Error starting domain: internal error: process exited while connecting to monitor: 
2016-05-23T23:54:21.548427Z qemu-system-x86_64: 
-device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=shared,bus=pci.0,addr=0x8: 
Virtio-9p Failed to initialize fs-driver with id:fsdev-fs0 and export path:/home/steve/shared02
2016-05-23T23:54:21.548491Z qemu-system-x86_64: 
-device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=shared,bus=pci.0,addr=0x8: 
Device 'virtio-9p-pci' could not be initialized

I then google researched, and discovered that (perhaps) virt-mgr doesn't like the source directory /home/steve/shared02, because it is not owned by the root user. I then tried a source directory of /mnt/disk1. This allowed virt-mgr to start the Windows 7 virtual machine, but did not provide any file sharing access. Then, I tried a source directory of /myshareddisk1, which (before the samba mounting) was owned by the root. This re-generated the error:

Error starting domain: internal error: process exited while connecting to monitor:
...

I then altered the mounting (mount //localhost/mydisk1 /myshareddisk1 -o user=root) and repeated the process: virt-mgr still produced the Error starting domain message. I then experimented within virt-mgr with various drive/mode combinations for the file system to be added - no joy.
