Virt-manager, KVM, Qemu and virtiofs problem fix

I had the following error in Ubuntu 24.04.

Error starting domain: operation failed: Unable to find a satisfying virtiofsd

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 108, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn
    ret = fn(self, *args, **kwargs)
          ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/share/virt-manager/virtManager/object/domain.py", line 1402, in startup

    raise libvirtError('virDomainCreate() failed')
libvirt.libvirtError: operation failed: Unable to find a satisfying virtiofsd

In my case, it was fixed with the following:

sudo apt install virtiofsd

Also, some people seem to have problems with the path. In that case, you can fix it by editing the XML like below.

<filesystem type='mount' accessmode='passthrough'>
  <driver type='virtiofs'/>
  <binary path='/usr/bin/virtiofsd'/>  <--- added this line
  <source dir='/mnt/virtual/download'/>
  <target dir='download_tag'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</filesystem>
