I managed to get xvdN devices working. Not sure what I did but they are
working. But when I switch file from file: to tap:aio it still failes.
I get this error:
2007-01-15 19:12:20 xend 4975] DEBUG (blkif:24) exception looking up
device number for xvda1: [Errno 2] No such file or directory:
'/dev/xvda1'
Here is the config (note this is fedora 6 instance 4):
name = 'fedora4'
memory = '256'
disk = [ 'file:/xen-build/fedora4/xen-D0.img,xvda1,w' ,
'file:/xen-build/fedora4/xen-swap.img,xvda2,w' ]
#disk = [
'tap:aio:/xen/fedora4/xen-D0.img,sda1,w','tap:aio:/xen/fedora4/xen-swap.
img,sda2,w' ]
root = '/dev/xvda1 ro'
vif = [ 'mac=00:16:e6:CD:49:5B' ]
kernel = '/xen/xen-3.0.4/boot/vmlinuz-2.6-xen'
#kernel = '/boot/vmlinuz-2.6.18-1.2869.fc6xen'
on_reboot = 'restart'
on_crash = 'restart'
extras = 'console=xvc0'
Any ideas?
Also, when I use the FC6 kernel the DomU just simply kernel panics. But
if I use the xen provided 32bit PAE then it works, just not real well.
