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