Re: [Fedora-xen] xen domain creation problem

I think the first error (about the ballooning) happens because there isn't enough RAM for your VM. Once you fix that, you should be able to run the installer properly. You may need to set your dom0 memory to your total memory minus 32MB (for xen) minus 256MB (for the fc5 installer). I have 512MB of RAM and it wouldn't work until I set the dom0 memory to 192MB. There's a line in my grub.conf that I modified to look like this:
  kernel /xen.gz-2.6.15-1.2054_FC5 dom0_mem=196608

As for the second problem, about the boot loader.... I'm trying to figure that out myself.

Hello. I am having problems getting xen setup and working on a FC5

What is the name of your virtual machine? vmxen
 How much RAM should be allocated (in megabytes)? 256
  What would you like to use as the disk (path)? /home/vmxen

 What is the install location?

If your install has exited, you can restart your guest by running
'xm create -c vmxen'.  Otherwise, you can reconnect to the console
by running 'xm console vmxen'
[root client ~]# xm create -c vmxen

I have attached xend-debug.log and xend.log files.

Any hints on what I should look at next ?
