Welcome to LQ!!! Since I only have general LQ&question-posting advice, but not technical expertise on this, I'll post it here, *in this to-be-closed thread*, instead of in your replacement thread, in the Rock forum, leaving that currently on
ZRT list.
Since
that thread hasn't received a reply yet, feel free to Edit it (as #1, instead of replying to your own post, which would remove it from ZRT list; btw, there's a typo: MV from from)
I'd suggest adding a bit more info to it: (via Edit#1, not a Reply if still ZRT)
specific info on the available resources status, in
CODE tags or via like termbin.com links
details on exactly what you tried, and precise info on results
what keywords you tried in web research; I found
this etc., from: rocks cluster create vm
I'm familiar with VirtualBox and its extremely detailed log facility, in case that might be useful, as a similar concept, for specifing host/guest resources, etc. details.
Best wishes. I'll ask for this Thread to be closed (LQ doesn't 'delete' things).
