Re: [Xen-devel] kernel Bug after upgrading to 3.0.2-2

["Brian Hays" <brian.hays@xxxxxxxxx>]

Already have it set. Here's my grub.conf settings ...

title Xen 3.0 / 2.6.16
        kernel /xen.gz dom0_mem=200000
        module /vmlinuz-2.6.16-xen0 root=/dev/sda2 ro

Thank you,
Brian

Please can you try booting setting dom0_mem explicitly on the xen
command line rather than relying on the the 'auto ballooning'
dom0_min_mem setting in the xend-config.sxp file.

Thanks,
Ian
