Here are my comments on this patch:<br>
<br>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
- When I open the dialog "Edit" on a VM without snapshots, the
error KCHSNAP0007E* is shown. That's because the VM doesn't have
snapshots but the UI should handle that and do nothing. Not having
snapshots is not an error from the UI perspective.<br>

Let us discuss why it returns a 404, anyway, the uri has nothing
wrong, to me, 404 means I am requesting a wrong thing.<br>

why sometimes it returns 500.<br>

is shown.<br>

Can you make the backend code more robust, I have to submit an empty
json below. If submit nothing, then error above.<br>

- I cannot revert to the current snapshot. The button "Revert"
becomes disabled whenever the current snapshot is selected. And
that's a very important use case. Suppose I just created a
snapshot. Then I mistakenly removed some files on my guest system
and I want to revert to that snapshot. With the current UI, I'm
not able to do that.<br>

Corrected since it can revert to current snapshot. By this way,
radio button add no value, so change back to original UI to make
revert an item level action.<br>

- There's no visual feedback when I click on the button "Revert".
When I click on it and the revert operation starts, nothing
happens. The user might click on it again thinking that the button
wasn't clicked on the first time. Also there's no way to know if
the revert operation finished.<br>

- If the user clicks on the button "Revert", closes the dialog
"Edit" and reopens it while the revert operation is still
happening, the error KCHSNAP0007E* is shown and the tab "Snapshot"
is rendered empty, even if there are snapshots to be listed on the
VM. The same problem also happens when the user clicks on the
button with the trash can, instead of "Revert", and closes the
dialog and reopens it while the operation hasn't finished.<br>

Seems like 'Revert', 'Create snapshot', 'delete', 'list snapshots'
are all exclusive, disable all buttons when any action is ongoing,
and only list existing snapshots when no snapshot creation is
ongoing.<br>
Revert is not a long task, it should response within 5 secs, then
user should wait there for it to complete, or else make it a long
task also.<br>

- Why isn't there a button "Revert" on each snapshot line? The
button with the trash can is there, the button "Revert" should
also be there. That's an action that applies to only one snapshot
at a time, just like delete. Other actions in other tabs, like
"Edit", are also shown on the relevant line instead of at the top
of the dialog. The button "+" is different, though, because it
doesn't act in one entry alone, it acts on the whole set of items.
So that makes sense for me to be at the top.<br>

Changed it back as it can revert back to current snapshot and radio
button has no value here.<br>

* Actually, the backend is raising the exception code KCHSNAP007E
(i.e. there's one '0' less), which is an invalid code. I'll send a
patch later to fix that. But the UI shouldn't worry about that
because the REST command returns the status code 404 in that case
anyway.<br>

Please correct all those 500 error above and below<br>
