Description Robert McSwain 2020-08-26 22:04:19 UTC 
Description of problem:
RHV Administration Portal fails with 404 error even after updating RHV-M. T

Version-Release number of selected component (if applicable):
 ovirt-engine-4.3.9.4-11.el7.noarch

How reproducible:
Unknown at this time

Actual results:
Manager occasionally returns a 404 error and requires ovirt-engine to be restarted to restore functionality

Expected results:
RHV-M / apache works as normal 

Additional info:
Errors such as the following are in server.log:

server.log:2020-08-03 18:52:07,853Z ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-3236) RESTEASY002010: Failed to execute: javax.ws.rs.WebApplicationException: HTTP 404 Not Found

This error: "RESTEASY002010: Failed to execute: javax.ws.rs.WebApplicationException: HTTP 404 Not Found"  occurs during the execution of which command in the background is still not known. This has been reported in the following BZ for a lower version of rhvm (4.1): https://bugzilla.redhat.com/show_bug.cgi?id=1467401

Another error from the ui logs: "Uncaught exception: com.google.gwt.event.shared.UmbrellaException: Exception caught: (TypeError) : Cannot read property 'a' of undefine" is reported in the bugzilla: 
https://bugzilla.redhat.com/show_bug.cgi?id=1669182, however which command from the rhvm backend lead to this condition is not known.

Additionally there is some comparison of engine logs for the time corresponding to the error reported in server log (RESTEASY002010: Failed to execute: javax.ws.rs.WebApplicationException: HTTP 404 Not Found), but it only showed the connection exception caused during connecting with the host.
Comment 10 Pavel Novotny 2020-11-01 20:48:34 UTC 
Verified in 
ovirt-engine-4.4.3.8-0.1.el8ev.noarch
ovirt-engine-webadmin-portal-4.4.3.8-0.1.el8ev.noarch


The NPE issue in Host detail -> Virtual machines with a migrating VM does no longer reproduce.
