Re: [Xen-users] Not enough memory to relocate the dom0 kernel image

Hi.

I have 32G total RAM in the box.

I try to suppress dom0_mem= parameter at config at tftpserver, in this case free says:

# free -h

      Âtotal    used    free   shared  Âbuffers   cached

Mem: Â Â Â Â Â 28G Â Â Â 277M Â Â Â Â28G Â Â Â Â 0B Â Â Â Â37M Â Â Â 120M

-/+ buffers/cache: Â Â Â 119M Â Â Â Â28G

Swap: Â Â Â Â Â 0B Â Â Â Â 0B Â Â Â Â 0B

I have trouble with xen booting on IBM System x3620 M3. My system is
gentoo. I use gpart and howtos to create partitions, I use grub2 as
bootloader. I try xen stable and unstable with same error (see attach).

How much total RAM do you have in the box?

Have you tried to suppress completely dom0_mem= parameter? In that case, how much RAM does your Dom0 see ("free")? And the Hypervisor ("xm list", "xm top")?
