Question 1:
I'm building a custom kernel with XEN 2.0.5 source install
but when trying to boot it says it can't boot
dom0 becuase there is not enough RAM.
I have 1024MB in this server, and have tried specifying a
smaller amount of RAM in boot params like so:

title           Xen 2.0 / XenLinux 2.6.10 TEST A (800MB)
kernel          /xen.gz dom0_mem=800M
module          /vmlinuz-2.6.10-xen0 root=/dev/sda2 ro console=tty0
savedefault 0

title           Xen 2.0 / XenLinux 2.6.10 TEST B (512 MB + VGA FB)
kernel          /xen.gz dom0_mem=512M
module          /vmlinuz-2.6.10-xen0 root=/dev/sda2 ro console=tty0 vga=0x313

but to no avail.
Any ideas?

Question 2:

Can I specify the 'panic=30' boot parameter on a xen kernel?
So that if it fails to boot a kernel, it will automatically reboot
and not hang there?

Thanks
Paul
