Re: xen in FC5 install

I have performed a basic FC5 install for the purpose of texting Xen. The machine is a Compaq Evo P4-1.5GHz with 384M of RAM.

I downloaded a CentOS 4.3 Xen image from the above URL for the purpose of testing, the CentOS image in question was designed for 128M of RAM so should run nicely on a machine with 384M.

kernel = "/boot/vmlinuz-2.6.15-1.2054_FC5xenU"
memory = 128
name = "centos.4-3"
dhcp = "dhcp"
disk = ['file:/xen/centos.4-3.img,sda1,w', 'file:/xen/centos.swap,sda2,w']
root = "/dev/sda1 ro"

Above is the contents of my /etc/xen/centos config file. Below are the errors I get in my /var/log/xend-debug.log file. The command "xm create -c centos" gives the error "Error creating domain: The privileged domain did not balloon!".
domain 0 grabbed all of memory and isn't letting it go. try adding

  dom0_mem=128000

to the end of the kernel line in /etc/grub.conf (saying kernel /xen.gz ...) and rebooting. I'd suggest going to runlevel 3 to avoid starting up X with so little memory.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
