Issue with folder sharing between host and guest os running using virt-manager

I’ve installed qemu, virt-manager using this article.
Now i’m trying to share files between host and guest os using these article 1 and article2 artiles.
However, I cant even run the virtual machine. virt-manager is showing this error-

-device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=/hostshared,bus=pci.7,addr=0x0: cannot initialize fsdev 'fsdev-fs0': failed to open '/home/arafat/KVM_Share': Permission denied

How can I solve this issue?
Thanks in advance for your help :smiley:
