Description Jenia Peimer 2023-06-05 09:27:21 UTC 
+++ This bug was initially created as a clone of Bug #2212312 +++

Description of problem:
Downloading memory dump using virtctl panics.
Either using create and download of memory dump:
$ virtctl memory-dump get myvm --claim-name=memoryvolume --create-claim --output=memoryDump.dump.gz
nor downloading last associated memory dump with the vm:
$ virtctl memory-dump download myvm --output=memoryDump.dump.gz


Version-Release number of selected component (if applicable):
4.14.0, 4.13.1

How reproducible:
Always

Steps to Reproduce:
Tests Suite.[sig-storage] Memory dump Memory dump with download [test_id:9344]should create memory dump and download it

Actual results:
memory dump download fails

Expected results:
Downloading memory dump using virtctl should work
Comment 1 skagan 2023-06-05 14:22:32 UTC 
Work Around:
Instead of using the get command with --output which gets and downloads the memory dump:
$ virtctl memory-dump get myvm --claim-name=memoryvolume --create-claim --output=memoryDump.dump.gz

you can do only get of memory dump and then download using virtctl vmexport download:
$ virtctl memory-dump get myvm --claim-name=memoryvolume --create-claim
$ virtctl vmexport download vm1-export --vm=myvm --volume=memoryvolume --output=memoryDump.dump.gz

For downloading only of the last memory dump instead of using the memory-dump download command:
$ virtctl memory-dump download myvm --output=memoryDump.dump.gz
Use the vmexport download after searching which is the last memory dump associated with the vm
$ virtctl vmexport download vm1-export --vm=myvm --volume={vm.Status.MemoryDumpRequest.ClaimName} --output=memoryDump.dump.gz
