Re: z/VM Live Guest Relocation (Was: z/OSMF....)

[David Crayford]

PowerVM had live migration in 2007 [1]. VMware released VMotion in 2003 
[2] so I guest the trailblazer was VMware.

Timothy,

I do not follow VM so I am not sure I follow. From your note saying that the 
extra charge feature was incorporated (this I understand).
Are you suggesting that a company just did a demonstration of what a feature of 
VM and called it their own?

When competitors achieve something it's a "clever trick" - when IBM finally 
catch up it's "innovative technology".

Now I remember why I unsubscribed. Enough.

Yes, and others saw that clever trick years earlier. Here's the history.

In July, 2010, IBM issued a Statement of Direction announcing its intention
to add Live Guest Relocation to z/VM. IBM then made Live Guest Relocation
generally available as part of z/VM Version 6.2 Single System Image (SSI)
on November 29, 2011.

http://www.vm.ibm.com/ssi/

http://www.redbooks.ibm.com/redbooks/pdfs/sg248039.pdf

z/VM SSI is an optional z/VM feature. On April 10, 2018, IBM announced that
z/VM SSI will become part of the base z/VM product in the next release of
z/VM, Version 7.1. IBM expects to release z/VM 7.1 in the third quarter of
2018.
