The code builds more-or-less cleanly with gcc-4.0; it is released as example code only — there is no guarantee it works reliably (or at all). The hypervisor is fairly specific to HP zx6000 machines in its drivers: it assumes a LSI MPT '909 fibrechannel disk driver. The guest patches are for Linux 2.6.18.
To build the hypervisor just type
the top-level directory.
To build a linux guest, apply the patch
gcc4.0.patch to a clean checkout of Linux (last tested on
the kernel build tree, and build with:
make ARCH=ia64 CROSS_COMPILE=ia64-linux- AFTERBURNER=$THIS_DIRECTORY/afterburner vmlinux
The easiest way to run the system is to use tftp booting. To run the hypervisor plus guest(s) set up elilo.conf as
image=/tftpboot/vnuma label=vnuma initrd=/tftpboot/vmlinux root=/dev/nfs read-only append="nomca maxcpus=8 simscsi=sd simeth=eth0 nfsroot=/srv/nfsroot ip=192.168.100.10:192.168.100.4:192.168.100.4:255.255.255.0:nodename"
for the master node, where
vnuma is the hypervisor built
vmlinux is the patched afterburnt linux
append= line is whatever's necessary for NFS root for your
system. In this case it says that the node's IP address is
192.168.100.10, the NFS server is on 192.168.120.4, the default route
is via 192.168.100.4, and the netmask is 255.255.255.0. Also this
host's name is nodename.
On slave nodes, elilo.conf is:
Vnuma initialises itself by broadcasting to find other nodes. so you need to boot all nodes within a few seconds of each other. Boot the slaves first, then the master.
