This takes us back to the wonderful world of Logical IOCS vs Physical IOCS. In the Mainframe world there as always been a diference between Logical I/O (the program's write of 80 bytes) and the Physical I/O (the writing of a 4K data block to a device by an operating system). In the PC world

Thanks for verifying that. So here is what I'm currently seeing. During the install I can see the Linux installer pinging my nfs server and it replys back but never reaches my Suse VM. I put a static route in the nfs server to point to the VM4.3 machine for the IP of the Suse install. This

It occurs to me that since the filesystem is what actually controls the buffer cache that one could write a filesystem for Linux on VM that ignores the buffer cache and does logical IOCS. Or maybe you need a DASD driver that does logical IOCS. The filesystem would probably need to do

No, it's the routers between you and the VM system. Unless that last router has a static route in it to pass the packet to the VM system, it will try to do an arp. When it gets no reply, it will drop the packet. This is because the IP address is in the same subnet as the router's NIC, so it

To do this, you need to enable PROXY ARP on VM TCP/IP. Check the VM list archive http://listserv.uark.edu/archives/vmesa-l.html for posts from Alan Altmark on PROXY ARP for intelligent explanations. -Original Message- From: Doug Griswold [mailto:[EMAIL PROTECTED] Sent: September 17, 2004

If you are correct and it can be done at the filesystem level, then maybe you don't even have to write a whole new one. I recall reading about the new ReiserFS 4 being modular, maybe you could just write a plugin. -jmc On Fri, 17 Sep 2004 09:06:18 -0700 Fargusson.Alan [EMAIL PROTECTED] wrote:
