Version-Release number of selected component (if applicable):
libvirt-daemon-9.5.0-7.el9_3.x86_64
qemu-kvm-8.0.0-16.el9_3.x86_64
virtiofsd-1.7.2-1.el9.x86_64
How reproducible:
100%
Steps to Reproduce:
1. Prepare a guest with the following xml snippet
<filesystem type="mount"> <driver type="virtiofs"/> <source socket="/vm001-vhost-fs.sock"/> <target dir="mount_tag1"/> <alias name="fs0"/> <address type="pci" domain="0x0000" bus="0x08" slot="0x00" function="0x0"/> </filesystem> <filesystem type="mount"> <driver type="virtiofs"/> <source socket="/vm001-vhost-fs.sock"/> <target dir="mount_tag2"/> <alias name="fs1"/> <address type="pci" domain="0x0000" bus="0x09" slot="0x00" function="0x0"/> </filesystem>
3. Try to start the guest
# virsh start avocado-vt-vm1
(Attach job hangs indefinitely)
4. check the guest status, guest will be paused
# virsh list --all Id Name State ------------------------------------- 5 avocado-vt-vm1 paused
Actual result:
Attach job hangs indefinitely
Expected results:
Should report some error like "socket has been occupied"
Additional info:
If I try to attach virtiofs device with the occupied socket to the guest:
1. Start a guest with the following xml snippet
<filesystem type="mount"> <driver type="virtiofs"/> <source socket="/vm001-vhost-fs.sock"/> <target dir="mount_tag1"/> <alias name="fs0"/> <address type="pci" domain="0x0000" bus="0x08" slot="0x00" function="0x0"/> </filesystem>
2. Prepare the following virtiofs device
# cat virtiofs.xml <filesystem type="mount"> <driver type="virtiofs"/> <source socket="/vm001-vhost-fs.sock"/> <target dir="mount_tag2"/> <alias name="fs0"/> </filesystem>
3. Try to attach the device to the guest
# virsh attach-device avocado-vt-vm1 virtiofs.xml (Will hang there indefinitely)
4. Cancel the above job by client:
# virsh attach-device avocado-vt-vm1 virtiofs.xml ^C
5. Then try to attach it again.
# date; virsh attach-device avocado-vt-vm1 filesystem1.xml; date Wed Dec 20 07:56:05 AM EST 2023 error: Failed to attach device from virtiofs.xml error: Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainAttachDevice) Wed Dec 20 07:56:35 AM EST 2023
