Moving ZFS root popol to a virtual server was: ZFS: Suspended Pool due to allegedly uncorrectable I/O error

Many thanks to David Christensen, Ronald Klop, and Peter Much for answering
my plea for help.

Further reviewing the available evidence,  it seems that the most likely
cause of the problem is someone at the data center
removing the disk drives from our server.  This was probably accidental,
not malicious. I have reported this to the hosting company, but
I'm not expecting much.

It is ancient hardware, circa 2011. Although it still performs decently. It
is probably time for an upgrade, particularly
since the hosting company is dropping support for bare metal servers.

I am not sure how to move the existing root pool to a virtual server. I've
tried a few simulations with VirtualBox, creating
a source server and a target. The pools get moved, but the target server
never boots (even when I remember to set bootfs).
Worse, the target disks are reported as being corrupted each time I do it.

Once again, any experience/advice here would be very much appreciated.

Thank you again,
Pammy
