I have created 4 virtual machine instances using xm create conf file path and it shows in GUI of virt-manager but when i trying to add more than 4 virtual machines in virt-manager it gives me "Error Device 5632(vbd) could not be connected. Failed to find an unused loop device". Is there any configuration to be done for running more that 4 instances.

Googling turns up:

What version of centos and libvirt are you using? Haven't heard this
issue for a while.
