Re: [Xen-devel] trying to debug xen4 & qemu-dm, Xen reports "core dump failed"

Hmm I could suspect parsing errors for the last comma in the disk option, or 
the empty vif ?


cat /etc/xen/vm/test.cfg

builder      = 'linux'
bootloader   = '/usr/lib/xen/boot/domUloader.py'

disk         = [
'phy:/dev/VG0/boot,xvda,w','phy:/dev/VG0/swap,xvdb,w','phy:/dev/VG0/root,xvdc,w',]
boot         = 'c'   #d is cdrom boot, c is disk boot
root         = '/dev/xvdc1'
vif          = ['']
vfb          = [ 'type=vnc, vncdisplay=102, vnclisten=127.0.0.1' ]
extra        = 'textmode=1 xencons=xvc0 elevator=noop'
maxmem       = 4096
memory       = 4096
vcpus        = 4
cpu_cap      = 100
cpu_weight   = 256
localtime    = 0
netif        = 'yes'
on_shutdown  = 'destroy'
on_reboot    = 'restart'
on_crash     = 'destroy'
