<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div>
Hello,<br><br>I am trying to install Xen, and I followed the directions at:<br><a rel="nofollow" target="_blank" href="http://www.howtoforge.com/ubuntu-7.10-server-install-xen-from-ubuntu-repositories">http://www.howtoforge.com/ubuntu-7.10-server-install-xen-from-ubuntu-repositories</a><br><br>The physical machine and Dom0 boot fine.<br><br>However, I can't seem to get any DomU to start.<br><br>
To clarify:<br><br>After I issue the "xm create xen_domu_name"
command, no errors are returned, and the "xm list" command shows
something like this:<br><br>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<br>Name ID Mem VCPUs State Time(s)<br>Domain-0 0 239 1 r-----
279.0<br>xendomu 7 128 1 -b---- 27.5<br>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<br><br>However,
I am unable to ssh into the VM, and typing anything at the "xm console"
screen yields no response. (Though, the "xm console" does show the
scroll back listed below.)<br><br>Any help would be appreciated.<br><br>Thank you,<br>Allen<br><br>Various outputs attached below:<br><br>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<br>DomU config<br>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<br>#<br># Configuration file for the Xen instance xendomu, created<br># by xen-tools 3.5 on Fri Nov 23 15:19:59 2007.<br>#<br><br>#<br># Kernel + memory size<br>#<br>kernel = '/boot/vmlinuz-2.6.22-14-xen'<br>ramdisk = '/boot/initrd.img-2.6.22-14-xen'<br>memory = '128'<br><br>#<br># Disk device(s).<br>#<br>root = '/dev/hda1 ro'<br>disk = [ 'file:/home/xen/domains/xendomu/disk.img,hda1,w',
