Memory problem between network and Xen

7 12 2010
It appears that dom-0 is taking all of the memory “not being used” so that when the memory runs out well before I have all of my VMs running. It can be fixed by assigning a static amount of ram on the dom0.

"xen_net: Memory squeeze in netback driver"

For fix the problem:

  1. Edit /boot/grub/grub.conf:
    On the “kernel /xen-3.0.3-1-amd64.gz″ line, add the following to the end of the line: dom0_mem=512M.
    (kernel /xen-3.0.3-1-amd64.gz dom0_mem=512M).
  2. Edit /etc/xen/xend-config.sxp and change the following:
    (dom0-min-mem 256) to (dom0-min-mem 0)

Once the dom0 server is rebooted, this issue will be fixed.
