John, Not yet, although there has been some discussion of how that might be implemented. The closest you can come right now is to define a vdisk as a paging device. If a page stays on the vdisk long enough, it will get put out to real VM paging volumes, otherwise it stays in expanded storage. A number of people (myself included) have played with this with good results.
Mark Post -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED]]On Behalf Of McKown, John Sent: Friday, December 13, 2002 9:42 AM To: [EMAIL PROTECTED] Subject: Linux/390 and z/VM interactions. I know that I should "use the code, Luke", but I'm not that familiar with the kernel et al. Does Linux/390 take advantage of any of the VM facilities when running under VM vs. in an LPAR? I'm thinking especially of the "handshaking" that is possible with paging. I.e. Linux thinks the page is in memory, but VM has it paged out. I think this is done with VSE and I remember it back in the OS/VS1 days as well. What about other VM-only facilities? More curious than anything else. -- John McKown Senior Technical Specialist UICI Insurance Center Applications & Solutions Team +1.817.255.3225
