Bug 1731428

Reproduce the bug with builds:
virt-v2v-1.40.2-5.el7.x86_64
libvirt-4.5.0-12.el7.x86_64
libguestfs-1.40.2-5.el7.x86_64
ovirt-imageio-common-1.5.1-0.el7ev.x86_64
ovirt-imageio-daemon-1.5.1-0.el7ev.noarch

Bug can be reproduced in non ovirt host.

Verify bug with builds:
virt-v2v-1.40.2-5.el7_7.1.x86_64
libvirt-4.5.0-23.el7.x86_64
libguestfs-1.40.2-5.el7_7.1.x86_64
ovirt-imageio-common-1.5.1-0.el7ev.x86_64
ovirt-imageio-daemon-1.5.1-0.el7ev.noarch

Steps:
1.Prepare a regular host(non ovirt host), Use virt-v2v to convert a guest to rhv with rhv-upload option:
# virt-v2v -ic vpx://root.73.141/data/10.73.75.219/?no_verify=1 esx6.7-rhel7.5-x86_64 --password-file /tmp/passwd -on rhel7.5-log -o rhv-upload -oc https://ibm-x3250m5-03.rhts.eng.pek2.redhat.com/ovirt-engine/api -os p2v_data -op /tmp/rhvpasswd -oo rhv-cafile=/home/ca.pem -oo rhv-direct=true -oo rhv-cluster=p2v

2.Wait until the transfer starts, and note the ticket value in ovirt-imageio-daemon log in ovirt host which the vm will be running on:
2019-07-24 17:09:21,371 INFO    (Thread-848) [tickets] [local] ADD ticket={u'uuid': u'ac2568cd-f49a-4ee4-973b-f9f813a760e5', u'ops': [u'write'], u'url': u'file:///rhev/data-center/mnt/10.73.224.199:_home_p2v__data/fc770a83-690b-4bd4-ab29-0696ce431a13/images/c31e480c-8b16-4879-8178-b940fc8b756c/a102f9ba-4b52-4647-a297-3e20d198e783', u'sparse': True, u'timeout': 300, u'transfer_id': u'e85a3b2c-b6bf-4ae5-88c0-983b48d10ef1', u'size': 12884901888}

3. Make the ticket expire in one second by sending this request:
curl --unix-socket /run/vdsm/ovirt-imageio-daemon.sock -X PATCH -d '{"timeout": 1}' http://localhost/tickets/ac2568cd-f49a-4ee4-973b-f9f813a760e5

4.Check the error message shows in the host:
# virt-v2v -ic vpx://root.73.141/data/10.73.75.219/?no_verify=1 esx6.7-rhel7.5-x86_64 --password-file /tmp/passwd -on rhel7.5-log -o rhv-upload -oc https://ibm-x3250m5-03.rhts.eng.pek2.redhat.com/ovirt-engine/api -os p2v_data -op /tmp/rhvpasswd -oo rhv-cafile=/home/ca.pem -oo rhv-direct=true -oo rhv-cluster=p2v

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

Result:There are no error info like: NameError: global name 'BrokenPipeError' is not defined.And the error info is correct when a ticket expires during import guest,so change the bug from ON_QA to VERIFIED.
