We are going with a lot of Linux Guests under VM. Close to 20 per IFL and are wondering about the experiences with the basevol/guestvol scenario. How many People accually use this scenario? How much DASD does this really save you? Is it worth the time and effort it takes to set this up? Could you just setup Links to specific disks in VM for a Guest like if you just wanted to share the binaries for say Oracle, or the /usr directory or /home directory? Wouldn't this accomplish the same thing? What would be the best way to go about this? It seems that you would definately save on DASD, but how much is the Question. Does SUSE support the basevol/guestvol out of the box, or are their some packages that need installing to make this work? How stable is it running under this basevol/guestvol scenario? hopefully this is not too much to ask question wise. Thanks in advance Hope you all can help.

Some people on the mailing list have implemented the "basevol/guestvol" scheme described here http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/sg246824.html Also, Bill Scully has a presentation for a simplified version of this at http://linuxvm.org/present/misc/basevol.html There's also a chapter on cloning Linux images in this Redbook http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/sg246299.html Mark Post -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Griffin, John G Sent: Wednesday, July 07, 2004 9:54 AM To: [EMAIL PROTECTED] Subject: Linux under VM and Cloning We have just installed vm 4.4 and are running Linux (SuSE 8). Our 1st linux virtual machine (directory entry) runs as follows :- vadd description size volume ------ ------------------------- -------------- ---------- 191 standard minidisk 0050 cyls 440w02 301 linux root 3338 cyls lxpb01 302 linux boot 0029 cyls lxpb01 303 linux opt 2145 cyls lxpb01 304 linux usr 1500 cyls lxpb01 305 linux var 1500 cyls lxpb01 306 linux home 1500 cyls lxpb01 My questions is we want to have one volume that all linuxes use their software from (both kernel and third party software, as on our linux we have db2 and some candle products) and 1 volume that is user specific so that when we are required to clone another linux vm we can just clone the volume that the system software is on. As for directory entries we use vmsecure so any automation we setup would have to take this into account.
