The Workloads table put a second line under memory and disk cells on
every stopped guest ("N/A / Unavailable", "- / Unavailable"), on every
agentless VM's disk, and "May include cache" under every agentless VM's
memory bar, even at 20%. None of them said why or what to do, and they
broke the row rhythm.
Memory that cannot be read now renders the same dash as an unreadable
disk, with its reason in the cell title, the sparkline's hover title
and assistive text. Disk shows a visible label only for a retained
reading (Last known) or a read the user can fix (No permission, Agent
error). The cache caption appears only when the guest's own memory is
at its warning or critical threshold, the figure that colours the bar
in host-share mode too, which is the case #2762 and #2639 were about;
below that the caveat stays in the title and assistive text.
An unavailable memory explanation names what is known instead of
"Unknown source": a powered-off guest reads "Unavailable while the
guest is powered off." MetricMiniSparkline gains an optional tooltip
so the chart covering the cell can carry that reason without changing
its accessible name.
