Critical issue with virtiofsd

General Discussion
1

Hi,
I have a VM with a virtiofs filesystem attached, my xml config contains following entries, so according to virtiofs doc everything should work, and it worked without a problem for some time

...
  <memoryBacking>
    <source type="memfd"/>
    <access mode="shared"/>
  </memoryBacking>
...
<filesystem type="mount" accessmode="passthrough">
  <driver type="virtiofs"/>
  <source dir="/srv"/>
  <target dir="/srv"/>
  <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</filesystem>

But after host reboot (I’ve changed some zfs module options and decided to restart the system) I’m unable to run my VM anymore.
A attempt to start the domain fails with error

libvirt.libvirtError: operation failed: Unable to find a satisfying virtiofsd

Also there is no “virtiofsd” file in the system, so I am unable to start a standalone virtiofs service, did anyone have similar problems on clearlinux?

my current CL version is 40580

//// EDIT
After download a fresh version of virtiofsd from virtio-fs / virtiofsd · GitLab and running it manually on my host and changing .xml entry to

<filesystem type="mount" accessmode="passthrough">
  <driver type="virtiofs"/>
  <source socket="/run/virtiofs-srv.socket"/>
  <target dir="/srv"/>
</filesystem>

I was able to run my VM, but sadly it feels like a bug in qemu package maybe? :confused:
