[Xen-users] unable to start more than two PVM hosts on one host

["Sebastian Reitenbach" <sebastia@xxxxxxxxxxxxxxxxxxxx>]

Hi,

I am using xen 3.1.0 on opensuse 10.3, for more details see below. 

When I try to start the third domU, then this will not work, I get the 
error: Error: Boot loader didn't return any data!
When I shutdown an other one, I can successfully start the machine that 
failed, see my log below. The xen configuration files are all similar to 
this one:

name="FTP"
ostype="opensuse"
uuid="da5e9cfa-1fba-72f5-9750-18c78d5a4e41"
memory=208
vcpus=1
on_crash="destroy"
on_poweroff="destroy"
on_reboot="restart"
localtime=0
builder="linux"
bootloader="/usr/lib/xen/boot/domUloader.py"
bootargs="--entry=xvda1:/boot/vmlinuz-xen,/boot/initrd-xen"
extra="xencons=tty "
disk=[ 'file:/vms/sys_ftp,xvda,w', 'file:/vms/swap_ftp,xvdb,w',
'file:/vms/log_ftp,xvdc,w',
'file:/vms/openSUSE-10.3-GM-DVD-x86_64.iso,xvdd:cdrom,r', ]
vif=[ 'mac=00:16:3e:6a:64:07,bridge=xenbr0', ]
nographic=1

Anybody knows what happens here, and maybe how do I get all four virtual 
machines running?


Kind regards
Sebastian
