Comment 1 Asher Shoshan 2019-08-19 13:19:04 UTC 

*** This bug has been marked as a duplicate of bug 1738620 ***
Comment 2 Fabian Deutsch 2019-08-19 14:35:01 UTC 
Asher, what kind of storage was this test using?

Also DataVolume (as in #1738620?) or something else?
Comment 3 Fabian Deutsch 2019-08-19 14:45:47 UTC 
According to Asher: ContainerDisk was used
Comment 4 Vladik Romanovsky 2019-08-19 14:51:10 UTC 
I don't see any errors reported here. Are we looking at the correct pod? 
I see that the pod in the description reached "Marked as ready" and didn't fail.
Comment 10 guy chen 2019-09-05 07:54:23 UTC

Comment 11 Marc Sluiter 2019-09-05 08:03:35 UTC 
Errors in the logs are somewhat expected, might be caused by the very limited cirros image.
The question here is: is the VM running or not? When this bz was reported, it was not, but the logs in the bz description were unrelated.
Comment 12 sgott 2019-09-05 13:18:38 UTC 
This image needs to be tested with a different VM that cirros to remove the noise from the logs.
Comment 13 Israel Pinto 2019-09-22 10:06:21 UTC 
Test again with fedora image (container disk)
HCO: hco-bundle-registry:v2.1.0-63

VM is running,
But same "noise" in the log:
