That was a good idea to check qemu-system-common to see if it had been altered but both dpkg -V and debsums report the files in the package have not been altered. The package is coming from the standard places:
apt-cache madison qemu-system-common qemu-system-common | 1:6.2+dfsg-2ubuntu6.22 | http://us.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages qemu-system-common | 1:6.2+dfsg-2ubuntu6.22 | http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages qemu-system-common | 1:6.2+dfsg-2ubuntu6 | http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages qemu | 1:6.2+dfsg-2ubuntu6 | http://archive.ubuntu.com/ubuntu jammy/main Sources But... this has nothing to do with it and I'm not sure what does. I rebooted the laptop and cannot reproduce the issue any more with any of the VMs that were not working yesterday. My suspicions lay with perhaps stale sockets left over since virtiosfd appears to have one per pid: # lsof -c virtiofsd | grep -i sock lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc Output information may be incomplete. virtiofsd 4292 root 3u unix 0xffff996fb37ccc80 0t0 67488 /var/lib/libvirt/qemu/domain-1-ubuntu22.04/fs0-fs.sock type=STREAM virtiofsd 4323 root 3u unix 0xffff996fb37ccc80 0t0 67488 /var/lib/libvirt/qemu/domain-1-ubuntu22.04/fs0-fs.sock type=STREAM virtiofsd 4567 root 3u unix 0xffff996f18858cc0 0t0 74528 /var/lib/libvirt/qemu/domain-2-sle15sp6/fs0-fs.sock type=STREAM virtiofsd 4587 root 3u unix 0xffff996f18858cc0 0t0 74528 /var/lib/libvirt/qemu/domain-2-sle15sp6/fs0-fs.sock type=STREAM I am typically quite rude to my VMs and will often just destroy them instead of shutting them down from the guest instance. Perhaps some of that activity caused things to go out of sync, only working after sockets were properly cleaned up by a host shutdown and reboot. Oh well. I'll close this and much thanks for allowing me to bounce ideas off this group and for the insight into how things are supposed to work. ** Changed in: qemu (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083988 Title: Cannot use virtiofs on Ubuntu 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/2083988/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
