[Libguestfs] failure to virt-sysprep (FC27?)

[Yaniv Kaul]

Since I upgrading to FC27, I *sometimes* fail to virt-sysprep.
The debug messages:
libguestfs: trace: set_verbose true
libguestfs: trace: set_verbose = 0
libguestfs: create: flags = 0, handle = 0x7f4600005dd0, program = python2
libguestfs: trace: set_program "lago"
libguestfs: trace: set_program = 0
libguestfs: trace: add_drive_ro
"/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-0_root.qcow2"
libguestfs: trace: add_drive
"/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-0_root.qcow2"
"readonly:true"
libguestfs: creating COW overlay to protect original drive content
libguestfs: trace: disk_format
"/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-0_root.qcow2"
libguestfs: command: run: qemu-img
libguestfs: command: run: \ info
libguestfs: command: run: \ --output json
libguestfs: command: run: \ /dev/fd/7
qemu-img: Could not open '/dev/fd/7': Failed to get shared "write" lock
Is another process using the image?
libguestfs: trace: disk_format = NULL (error)
libguestfs: trace: add_drive = -1 (error)
libguestfs: trace: add_drive_ro = -1 (error)


Any ideas?
TIA,
Y.
