First Experience with Xen3 on amd64 (Thanks, Bouyer!)
Hello world,
I must confess I have been waiting for the release of the amd64 port for
asome months now... to be precise since I bought this Xeon 5120 in this
PowerEdge 1900 server, around june I guess.
Since the release I have built up a testing environment using -daily
from 20071215 (kernel 4.99.42). And the latest xenkernel3 and xentools3
packages. I did make my own kernel with VT100, Veriexec and CGD support,
based on the config of the XEN3_DOM0 kernel.
For this test I have:
kern.securelevel=-1
kern.veriexec.setric=0
So far so good. The problem appears when trying to bring the first DomU
up, with the following config file:
kernel = "/netbsd-INSTALL_XEN3_DOMU.gz"
memory = 128
name = "machine"
vif = [ '' ]
disk = [ 'file:/mnt/virtual/netbsd-common.img,hda1,w' ]
When bringing up xend, in the logs I have:
xend-debug.log:
