Comment 1 Justin Sherrill 2018-05-21 13:09:05 UTC 
Temporary Workaround:

Apply the included workaround.patch, restart httpd.  This will stop returning the 'hypervisor' information for the subscriptions that are erroring.  This will allow the user to still access the relevant pages until a proper fix can be done.

Comment 10 Jitendra Yejare 2018-09-07 12:02:31 UTC 
@Justin,

Need steps to repro/Verify this bug. Is it required to have virt-who subscription in manifest ?
Comment 11 Stephen Benjamin 2018-09-07 12:55:06 UTC 
We do not know how the original customer got into this state, I believe a no-break test would just be fine: set up virt who and some VDC subs.

The only other way is to manually assign a hypervisor id that doesn't exist to a pool, overriding any rails validations.
Comment 12 Jitendra Yejare 2018-09-19 12:02:42 UTC 
Verified!

@ Satellite 6.4 snap 22

Steps:

1. Import manifest with VDC Subscriptions.
2. Register virt-who clients to the satellite and add the virt-who subscriptions to the clients.
3, Upgrade Satellite 6.3 to 6.4
4. Verify the subscription page and virt-who clients.


Observation:
1. The subscription page post upgrade is not errored out and showing the subscriptions correctly with clients.
2. The virt-who clients are intact post upgrade and subscribed.
