I forgot mention - reboot after changes.
If you want more memory to dom0, you can change it via xe
vm-memory-target-set for Control Domain for your host (you can get dom
uuid from xe vm-list with 'control domain' in name-label).

Thanks for your assistance. Tried it, but still makes no difference.

1) don't use xend (or it configs). xapi or xend, not both.
2) Proper setting is
/etc/default/grub
# Start dom0 with less RAM
GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=1024M"
and do update-grub after changing default.

Hi,
I've installed xcp (xcp-xapi) on Ubuntu 12.04 - installed, but
have gotten no further. What's stopped me dead in my tracks is
that Xen appears to grab most of my 6GB of memory - well,
*something does* - leaving only 1GB for me to run my desktop on.
Very slow and painful to use. (It would be ideal to run this on
a test server, but nothing is available.)
First, do I understand correctly that "dom0" is just the host
system? In other words, when I boot the Xen kernel, that's dom0, yes?
Here's what I've tried up to this point.
Edited /etc/default/grub
GRUB_CMDLINE_XEN="dom0_mem=2G,max:2G"
also tried
GRUB_CMDLINE_XEN="dom0_mem=512M,max:512M"
... followed by update-grub command.
Edited /etc/xen/xend-config.sxp
--------------------------------------
xend-config.sxp:(dom0-min-mem 2048)
(enable-dom0-ballooning no)
All mods followed by reboots, of course. None seems to make any
difference. The performance monitor application and "free" command
show just under 1GB available when booted under the Xen kernel,
6BG when booted under normal Ubuntu.
Xen reports the proper memory stats:
# xe host-list params=all | grep memory
memory-overhead ( RO): 83017728
memory-total ( RO): 6372888576
memory-free ( RO): 5120520192
memory-free-computed ( RO): <expensive field>
Have I missed some basic concept somewhere? Anyone have similar
problems?
Cheers,
Lyn
