As one of the SWAPGEN authors, I've watched this discussion.
I'd note that Barton's original statement stands, in the context in which he
said it: VDISK has always provided better *performance* in every observed case.
The concerns about using up real memory have never been supported by the data

Hi Dave,
The SWAPGEN creates the VDISK and the zLinux does accept the disk. But
swap is not activated on the disk. To activate the swap I have to issue
a mkswap before swapon. And after booting the guest it must be done again.
I don't know if it is a problem with swapgen, with linux or some
of SWAPGEN into my
VM but
no success so far. I have tried every way I can do a filetransfer but
every time I end up in a file I can't use on VM. Can anyone send me the
VMARC-ed version of the current SWAPGEN so I can continue? I do have the
old version here but there seemds to be a problem with my VDISK

It's in MAILABLE format because it's actually a package of several
files.
Download the MAILABLE file to your VM system. RENAME the file to
SWPG0803 EXEC and run it to extract the 11 encoded files. Use and
enjoy.
I've removed the extraneous line end from the copy on
www.sinenomine.net. Should be happy now.
(crossposted to Linux-390 and IBMVM, since many folks support either
Linux systems or VM systems or both)
Posting a recent update to SWAPGEN prompted several people to contribute
additional goodies, so I've posted a new version of SWAPGEN (version
0803). The file SWPG0803 MAILABLE
