Description Kedar Bidarkar 2020-02-07 19:01:29 UTC 
Description of problem:

rhel8-tiny  templates seems to have only 1Gi instead of 1.5Gi as seen minimum from osinfo-db rhel-8 xml file


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

CNV-2.2

template.kubevirt.io/version: v0.8.2
name: rhel8-server-tiny-v0.7.0



How reproducible:

Create a VM from the base rhel8-tiny templates


Steps to Reproduce:
1.
2.
3.

Actual results:

Virtual Machine created from any rhel8-tiny templates seems to have only 1Gi of memory.


Expected results:
Virtual Machine needs to have minimum 1.5Gi instead of 1Gi memory as seen from the osinfo-db rhel8 files.

Additional info:
Comment 1 Kedar Bidarkar 2020-02-07 19:03:51 UTC 
Below is the output from both rhel8 templates and osinfo db files.

I believe even the Validation values need to be updated for rhel8-tiny templates.

Comment 2 Ruth Netser 2020-03-18 11:16:32 UTC 
Verified:
1. All RHEL8 tiny flavor templates now have memory: 1.5Gi memory:

$ oc get templates -n openshift rhel8-server-tiny-v0.7.0 -o yaml | grep -A 1 "requests:"
            requests:
              memory: 1.5Gi
$ oc get templates -n openshift rhel8-highperformance-tiny-v0.7.0 -o yaml | grep -A 1 "requests:"
            requests:
              memory: 1.5Gi
$ oc get templates -n openshift rhel8-desktop-tiny-v0.7.0 -o yaml | grep -A 1 "requests:"
            requests:
              memory: 1.5Gi


which match the validations minimum (1610612736)

2. Created a RHEL8 server tiny VM from the UI - VM is created and started successfully.
